I could be wrong but I feel like they mainly did it just for the fuel economy numbers "on paper" as they say. We all know it isn't guaranteed to have better real world MPG but automakers have been putting lower powered, or smaller displacement, engines in some models to improve their fleet fuel economy average. It's also the reason they put auto stop/start in damn near everything. JUST to look better by the numbers.
@@JasonYergin I remember hearing that the engine was intended for the Colorado, but the development of the third gen was delayed so they ended up putting it in the Silverado and some Cadillacs.
2022 silverado 3.0L diesel I6 owner here, just today I did a run for about 106 miles at around 68-70 miles an hour, got 31.7 mpg out of it, shit’s crazy and so damn smooth cuz of that 10 speed transmission, best of both worlds
5k miles in on my 2023 LZ0 Duramax. It has been absolutely fantastic. I live in Colorado, and that turbo diesel is the way to go to maintain power at elevation. It tows amazingly in the high country, and the fuel economy is otherworldly for a full size
I love diesels, but with the emissions and the corrosive as hell def. I will never buy another one. Every issue with emissions costs a ton of money. And here's the kicker. 25 years ago you wouldn't even know it happened. Cis that shit wasn't on there
6.2 all day long, got one in my 22 Denali and absolutely love it, my second choice would be that Duramax my buddy has one in a Trail Boss and is getting 30.4 mpg and he loves his
I bought a 2.7 back in May. Granted its my first truck, but I truly have no complaints on how it drives or performs. I got the six seater and took a family trip and everyone was comfortable. The gas mileage is amazing if you aren't driving like a manic.
I had one but traded it in. The 2.7 had no issues other than lag, but why tax 4 cylinders when you can use 8 cylinders to split the workload. PSI and RPM kills engines. To each their own. 2.7 has plenty of power, but I got 23mpg in the city. 16 with the 5.3.
Yeah me too love the 6.2 think it's the best non supercharged v8,. That is unless Ram decides to put a 6.4 392 engine. Hello Ram make it and I will buy it.
@@thorpower1015 I put a 6.4 SRT in my single cab short bed ram…. They should’ve done it from the factory for sure! Way more power than my 6.2 chevy but they both have their purpose.
I have the 3.0 in my 2022 GMC Sierra (refresh) AT4. Have under 7k miles and I average 28-30 on the highway. My best 50 mile range is 34.4 mpg!!! Was going to get the 6.2 but during production they ran out of inventory so I chose the 3.0 diesel; great choice. Love this engine!!
The new diesels are awesome, but the emissions are trash. I personally know 2 people who own them and they'll never waste another dollar on them ever again. FCK man my personal favorite for the real Duramax obviously the 6.6 is 04-07 when emissions weren't nearly as disastrous, it actually destroys the engines, shuts them down entirely so wtf? Junk! I have a 2011 Sierra lc9 which is already legendary for bulletproof reliability but! What brings it down? Emissions the EVAP system is/was notorious for always being on, FCKNG bllsht but GM was forced to comply for EPA credits meeting the federal mandate somehow. Just goes to show you can have the most reliable (legitimately with the 11 lc9 5.3 ) yet 1 little "flaw" brings down the entire vehicle. I know how to cheat the system for a sticker but a lot of city boys don't so wtf. And the LC9 5.3 EVAP issues is NOWHERE as bad as the tiny new 3.0 inline 6 diesel, I feel for you man honestly. Do as you wish, as I truely wish you the absolute best of luck no matter what, but dump that whore for a proper 5.3 or a nasty 6.2 they're damn near bulletproof engines still in a world of unreliable Garbage. Even Honda, Toyota (that never make powerful engines) are having severe reliability issues making a tiny engine push too big a vehicle. The Honda problem is their legendary 1.5 l direct Injection Turbo, there's so much pressure being forced into the engine that the fuel bypasses rings which dilutes the oil popping them in less than 50k!!! In a dam Honda!!! Only GM has cracked the code, the 2.0 direct Injection Turbo is reliable but some have in fact had issues but it is accepted as a very reliable engine. The other will copy them, if not already buying GM tech like toyota, Ford, Honda and others lol
@@SkinnerFurniture awesome to hear 👍 I assume youve had good luck this far? Straight up wish you the best of luck Man, the rediculous cost of trucks today cannot be reasoned with other than pure greed pure and simple. Which then requires the dealer/GM to step the fck up and fix their product if required. This is what/when good or bad dealers are made
Ben remember these trucks run on different fuel. Diesel better mileage but higher fuel cost. 6.2 premium 5.3 87 octane and 2.7 regular octane. More RUclipsrs need to explain this to people
We've put alot of miles on a pair of 6.2s buying 87 octane. You hear the occasional pinging if you listen real close. Fuel economy is about the same as 91 empty. Towing 91 is better i would say.
Agree. Cost per mile is the real key, but isn’t consistent with upgraded fuel having different markups in different locations. For example, diesel is $1.5 more than regular in NC right now.
@@BabyGators This is insanity, how gas can be cheaper than Diesel today, I remember 30 yeasr ago when people consider diesel as disposal waste and cost less than $2 per gallon. hope this not continue for so long.
@@sam79357 it is insanity, but you can thank absurd regulation for the swap in fuel prices. The amount of taxes on diesel don’t help either. It’s a shame because it’s much better, more energy dense fuel.
I have a 2019 5.3 8-speed DFM Silverado. So far I really love the truck. In my opinion this engine hits the sweet spot of efficiency, power, sound, and drivability. GM has done a great job of coming up with a lineup of engines that seem to suit the needs of just about anyone's needs. I do like the diesel but between the premium cost to get it, plus the extra cost per gallon of fuel along with DEF fluid and the fact that maintenance will probably cost more than a gas engine, I would probably steer away from it unless towing were the main concern. The 6.2 makes great power but really requires premium gasoline. The 4 cylinder is an interesting option. I would like to see how it fairs for reliability over the coming years.
Exactly, people need to get over the fact that the cylinder count is small. That is light a deep latent bias, that is not really valid when I have seen turbo'd 4's produce well over 500HP. The cylinder count thing changes with technology. Even the heftiest diesels are often just 6 cylinders. And then there is the durability argument. Sure Turbo's run hotter and durability will be an issue, but when, 200,000 miles. Do most people even drive the rigs that long and for that many years? Mostly "no". The Turbo Diesel 3.0L seems to be the sweet spot.
My duramax 3.0 does exactly what I bought it for. 34 mpg on the highway all day long. Towing is amazing with the low end torque..... 25 mpg around town & it's a 4x4...... rst 4x4 standard bed Z71. I haven't had any mechanical issues so far. Love my truck
@@flandrescarlet486 I have 80k Miles living in MN. I have never had a problem with the winter. Many times I havent plugged it in and it has started at -1 to -20.
I bought the Duramax end of May, and it's the best at towing, and I averaged 24 mpg hwy/city last tank. Obviously it goes down when towing, but it's still way better than gas!
if you don't mind me asking how many miles per tank avg ? and are you worried about oil pump belt replacement on the gear train at the back of the motor?
I have A 5.3 Tahoe pulling a 19’ bass boat, and have just upgraded to a 6.2 Denali Yukon with Cat back exhaust. Have to say the extra HP is appreciated ! And the sound is GREAT!
Guess I'm the only one here with a 2.7 silverado (2021). But, I love it. It has not disappointed me at all yet, with 28K miles on it. It's so easy to drive, and I almost forget it's smaller
I have a Silverado with the 6.2 and Max Tow package and tow a 12000 lbs boat. No problem whatsoever towing the boat. I was amazed when I was on flat terrain I was only turm 1750 RPM at 72 MPH
As much as I love the low end torque of the 3.0 duramax, it can't beat the sound of a 6.2 v8, that's probably the motor I would be going with if I didn't already have my 3.5 ecoboost expedition, great comparison ben!
6.2 seems like a great choice at the surface level but week to week, pumping premium fuel into the 6.2 doesn't seem like a great choice, especially because the 5.3 is a great option and is tuned for regular fuel.
@@aldenklemmrx18 I don’t think they are tbh I looked at a jd power consumer report so far no reports on the 22 or 23 trucks but tons on the 2021 n some older models.
I got the 2.7 cause I got a Custom blacked out for 38 grand brand new. Sharp looking truck, interiors kind of basic, The ones in the vidoe are much nicer but its work truck mate. Ive gone from the 5.7 to the 5.3 to the. 4.3 and now the lil turbo and so far its my favorite.
I bought my truck in 2020 so it has 45 more horsepower and 35 more ftlbs of torque. Tow rating of 9800 pounds which is 3000 higher than the 2.7 of 2020. I also don't worry if the open deck design of the 2.7 will handle the 20-30 pounds of boost without cracking the engine block or failing a head gasket. Fords open deck 1.3, 1.6, 2.0 and 2.3s have had these issues for the past decade but whatever.
I test drove a 2022 with the 3.0 Duramax right after I bought a 2017 with the 6.2 and I'm here to tell you that 6.2 torque feels alot like the diesel, loving the gasser.
Just bought a 2023 ZR2, traded in my Silverado 1500 with the 5.3. The 6.2 is the only flavor offered in that trim, but I'm not disappointed whatsoever. Fuel economy could be a bit better but all things considered, I think it's the best choice for me. Definitely should have opted in on the available Borla cat back exhaust. I see upgrades coming :)
I have a 24 duramax. My first diesel. Love this motor. It drives effortlessly. Smooth quiet and can tow almost anything. 30 mph on long trips. Seems like a no brainer.
I drive a Denali Duramax with the LML. I've had an LLY previously. I live at 5600 feet. love the power of the Duramax. I also am building a 37 Chev PU with an LT!/L83. and a 6L80E. It'll be interesting to see what it does in the mountains.
Great comparison video Ben! Also, thanks for showing us the payload and towing stickers. Please do that in all your videos with vehicles able to tow. Thanks!
@@streetrider4130able So, the manuals all say "Zero break in period. Tow at full GVWR immediately?" Porsche is the only engine maker that I'm aware of that does engine break-in at their factory. Each engine gets a full hour on the engine dyno, after which all fluids are dumped. Then each car is taken for a test drive up to 80% of top speed on the autobahn before final shipping to dealers. Chevy ain't doing that bro. 😂
@UpsForDays diesel will always have more expensive service and maintenance. If you are getting a 2022 and older model there is a rather pricey service at 140k-160k for a belt that needs to be changed and takes a ton of labour. But 2023 they re-engineered it to dodge that labour cost.
@@upsfordays4662 maintenance is not bad at all. The gas milage and longevity will pay for itself. It like driving Honda civic that tows 9500lb…lol. I have two vehicles with 3.0 durumax no regrets.
I'm the proud owner of a 2006 1500 with a pre-AFM 5.3l engine. The thing is rock solid, plenty of power and nice gas mileage. Every time i go to the dealer for an oil change (They often have the best price these days), they offer to buy my truck. They tell me that I don't have to buy anything from them, they just want my truck.
Last time I was at the Chevy dealer a salesman told me they were instructed to push the 2.7 because nobody wants one. It's pretty much all they had on the lot anyway. As for me, I made my decision in 2019 and went with the 6.2 with the 3.42 axle and max trailering package. The thing tows like a beast.
I think a lot of people are skeptical of the 4 cylinder engine. Many remember the “Iron Duke” Camaro’s from the 80’s, and assume that the new 4 cylinder trucks are underpowered and virtually useless when it comes to towing a trailer and doing truck things. They’re definitely not underpowered. But Chevy needs to convince people to try them!
My local dealer had six of the 2.7s on their lot when new vehicles were hard to come by. The salespeople were literally begging people to take them. I'm personally less scared of the 2.7 and more scared of the 8 speed that they pair it with.
The 4 cylinder is a brilliant option. What do I mean when I say that? It's for a large portion of people that want a truck but don't actually need a truck. I see way too many people in office parks with top trim trucks that will probably never tow anything or carry anything in the bed more than a small trip to Home Depot.
If you’re going for fuel mileage, then Duramax is the way to go. I personally have always had the 6.2 L. You can’t beat the sound the feel of a 6.2 L V-8 I just couldn’t bring myself to get a diesel especially with the price of gas and people running out of diesel this year. Great review all good comments but I’ll keep the growl of my V8 😂😂
2.7 HO or the 3.0 Duramax all day for me. I've got a 2022 refresh with the 2.7 HO and its fantastic. Came from a few GM V8s and a Colorado 2.8 Duramax prior to it. The torque it delivers is meaty throughout, and the 5049lbs curb weight (crew cab short box 4x4) more than makes it peppy. Plus engine construction wise its all forged bottom end and tri metal bearings just like its diesel brethren. Your comparison on the 2.7 vs the 5.3 I've had the opportunity to verify on GPS based 0-60 timing. My 2019 old body 5.3 double cab (just shy 5400lbs curb) was good for 6.85 seconds to 60mph. My 2.7 HO (5049lbs) was 6.9 seconds.
In july, I bought a 2020 RST with the 3.0 Duramax with 35,900 miles. I love it. I do a lot of highway driving. The fuel economy is incredible. Im averaging 22-24 mpg all over the northern half of Arizona. I live in the Phoenix area.
The one thing that disturbs me about the Duramax is they use a wet belt to drive the oil pump at the back of the engine. The timing chains are also back there.
I'm more interested in the longevity aspect of these engines. I'm a mechanic on a fleet of around 30 Isuzu box trucks with the GM 6.0 engines. Half of which have over 300,000 miles on them. I have my doubts we'd have the same results with them turbo 4 cylinders.
That 6.0 gas was one of GMs best engines ever. Darn near bulletproof. Almost bought a 06 1500 Hd with the 6.0 once. I should have. I’m curious to see how the new 6.6 gas in the 2500 is going to fair long term.
Additives, additives, additives. If I treat my fuel and oil I don't get the DPF related check engine lights. I used Hotshots EDT in the fuel and FR3 in the oil.
The added emi$$ion$ required by big brother on the diesels, plus gas being cheaper than diesel by about a buck a gallon in the NE, would have me opt for the 5.3. And I’m a diesel lover too.
These modern diesels are all like this. Dealers do a TERRIBLE job of not explaining that they absolutely cannot just be driven around town. If you're not on the highway a lot, or at minimum driving in an area where you get long stretches without a traffic light or stop sign, then you are just asking for DPF issues. And you have to keep the oil changed at least twice as much as the manufacturers say you do...I never go more than 6,000 miles without an oil change.
I switch from the 6.2 to the Duramax 3.0 and I have to say Duramax in a half ton truck has been the best decision GM has ever made! that engine is solid I don't think I would ever go back to the 6.2!
I’ve had 3 F150’s for the past 8 years (I drive a lot for my job so I trade in often) and consistently get 21-23mpg with my 5.0. I’m considering a GM product in the future but man the fuel mileage on the V8’s are pretty horrible compared to the competition, I’d be look at the diesel personally.
I have a 23 Denali Ultimate I just got this week with the Duramax. I like it so far but I don't really have enough time with it to know much but I have had plenty of the v8s and it sure seems I have pretty much always gotten better mileage then what is claimed. I know I get better numbers in my Suburban then what is claimed. Even running flex fuel pretty sure I get better numbers and I am positive you loose like 15-20% economy with flex fuel only reason I ever buy it is its normally $1 cheaper per gallon but the last time I bought it, it was only like $0.25 cheaper. Gas has went up so much the last month here it was $2.99 like 3 weeks ago now its $3.40 range and diesel is only $0.45-0.55 more.
Hi Ben , big fan of your channel. Here’s a suggestion for a in the future, down the road video. Re-do this comparison test with all four power train options and give a update of j h ow they aged in feel, drive ability, and mileage. Plus see if you can determine how each power train held up and their costs. Just a thought….. Bill
It seems like they put the 2.7 liter 4 banger in some Silverado's just for the fuel economy numbers "on paper" as they say. We all know it isn't guaranteed to have better real world MPG but automakers have been putting lower powered, or smaller displacement, engines in some models to improve their fleet fuel economy average. It's the same reason they put auto stop/start in damn near everything. JUST to look better by the numbers, according to the EPA's official fuel economy rating.
A lot of people are upset over the 2.7's fuel economy. And what I mean by that is that there's a class action lawsuit brewing because the promise of 20+ highway has generally been unmet. Which is pretty sad because the 5.3 actually can, and will last 3 times longer as long as you defeat the cylinder deactivation. I suspect the real reason for its existence is as an insurance policy for when diesel fuel becomes prohibitively expensive and/or unavailable over the next few years.
I test drove a 2.7 sierra a couple weeks ago. Wasn't impressed. Turbo sounded like a Jetsons car so I wonder if all was working right. Heard a tapping with revs... Couldn't tell if it was injector noise or lifter noise. Either way, it didn't do anything to convince me it was worth any attention. Real world mpg isn't much better than 5.3, often worse. Towing mpg is easily beaten by every other engine option. Extra complexity of a turbo makes me worry about long term reliability.
I just traded my 2018 Sierra 5.3L loved it until start consuming oil at 60k miles now I have 2023 Silverado 3.0L Duramax 2nd generation and love everything about this baby diesel
I am here as the 4cyl 2.7HO 8spd whipping-boy. With my 1 month "ownership" of a 23 LT, I can say that I absolutely love the daily drive...fast, tight and decent efficiency. It tows my 5500lb TT very nicely up 6% grades. My particular 8 speed in my silverado though.....it feels kind of clunky from 3 down to 1st when stopping. It also feels that when I am in traffic, it lurches a bit around d 2nd to 4th? Not sure, it's new to me compared to my 02 silverado and my 08 tahoe, both with 4L60s. All said, my '23 LT is pretty bitchen.......(boomer alert)
I have the 5.3 but installed Pulsar LT to disable DFM AFM. Straight 8 all the time. The gas mileage sucks but it’s got all the power I need. Can spin 33s no problem
I went with the (GMC) 5.3L. This was after owning the 6.6L Duramax in my 06 2500HD. Honestly LOVED that 6.6L and if I thought I'd do even half the towing I used to, I would of gone with probably the 3.0 Duramax. I'll admit the spike that Diesel took also scared me off.
Good review when I first thought of a new 22 Silverado I thought of getting the 2.7 after having 2 previous 5.3 but the fuel economy wasn't really any better than the 5.3. In Canada the 5.3 is about $2k over the 2.7, the 3.0 is about $700 more than the 5.3 but if you factor in that it comes with a block heater which is a $195 option on both the 2.7 and 5.3, $500 more is a no brainer to get the 3.0. My 22 order was never picked up but got a 23 with the LZ0 time will tell if it's as trouble free as my previous 5.3' s were but agree it's probably the best all around power train in a half ton pickup right now.
Diesel for MPG‘s and if you’re driving a lot, 6.2 for fun, 5.3 maybe best overall and 2.7 for low cost and low emissions. If you’re worried a about lifters, first or last.
They already have. US car manufacturers are about to have a very very rude awakening. 2023 will be one of the worst years on record for GM, Ford & Dodge.
@@leftycosta1899 Unfortunately for the consumer gm has finally figured out the law of supply and demand. They are no longer flooding the dealers lots, keeping supply low keeping them from throwing money on the hood to move inventory.
My husband is a Chevy guy. We currently have a 2021 with the 6.2. We were Leary of it as we alway had the 5.3s. What I can say is our 6.2 gets better gas mileage than our last with the 5.7. The 10 speed transmission does make a difference. We have been pleasantly surprised!
@@ktpinnacle on a recent trip to the coast we averaged 24 mpg. Around town around 20 mpg. We had an Avalanche (2012) that we loved with the 5.3 and were lucky at times to get 20 on highway trips. 17 in the city.
after watching mechanic reviews of the duromax, especially the fact that engine is set basically backwards where all the maintenance issues are on back of motor, and the fuel pump will need replacing every 100k,, and Def, and diesel costing an average of 50 cent more plus the fuel filter cost,,, I m sticking with V8 gas 6.2
I'm pretty satisfied with my 5.3...I know it's basically the same as the one from 2007, but the 10spd really improves the drivability. That said, I didn't have many options available when I bought it last summer. If I'd had I suspect the 2.7 would be in my garage now. I'm trying to not find an excuse to drive one as long as I'm happy with the 5.3! 😆
MY 07 and my 13 Silverado with the 5.3 both used oil like I owned a well. 2-3 quarts between 5000 mile oil changes. The dealership told me that was normal oil useage. Now I drive a Toyota Tundra.
I have a 6.2 and a 3.0. I wouldn't recommend the 3.0 for your average short trip grocery getter. The 6.2 is really fast and it sounds great with a cat back. The 10 speed in my 3.0 grenaded at 54k. I run the 3.0 as a work truck, it gets a 150+ miles a day and idles all day. It's perfect for that.
Every engine has "problems" arise. Not sure the Duramax has many issues. They did a revision to make it better but none of the reported issues were big. The 6.2...if I am not mistaken may be in a class action suit for lifter issues. Could be the 5.3 as well? But if true...thats a "problem"
One question that might be a good point about this motor on GM trucks is range. If range matters and GM still hasn't kept up with the competition with a larger fuel tank offering, this is the only way to get a longer range. So, if that matters, this is another benefit and/or factor in the ROI discussion
The Pulsar LT is a nice tool for throttle sensitivity. But a tuner will give you that same option while actually adding power. I love my Superchips tuner on my '21 6.2 Trail Boss!
@@thorpower1015 they claim up to 45 horse to the tires in the mid range on 93 octane, peak about 17 horse. I don't have 93 around here so around 35 horse for me. I can definitely feel the difference though!
Ive had an 09 Denali with the 6.2 AWD and i cant imagine having any other powerplant. Im in the market for something else right now and not looking for anything other than a 6.2. Hell of a good engine. Right before they put AFM b.s. in em.
Spent 3 years driving my 2020 with the 2.7 and never missed the V8. In over 22k, the truck averaged 20.1MPG total. New 23 is also a 2.7 but the extra 82flbs of torque are immediately noticeable. For me, with the current price of these trucks, the deals on the 2.7 were an easy choice. That being said, I lease so no warranty issues but I would be concerned about long term ownership. Also, the reprogrammed 8 speed trans is definitely improved over the 2020 version.
@@jnmcs You didn't save anything. Leasing guarantees you will have a car payment forever. You are burning money to borrow a vehicle. My V6 Toyota SUV gets 28 mpg average, 30+ on the highway. These smaller engines are cheaper to produce, get worse gas mileage and will die far sooner than a proper V6 or V8.
The LT based small blocks (6.2 & 5.3), despite the DFM lifter issues are the most solid choices for the average person. The 2.7 is a solid engine but towing or hauling it would be pushed to its limit, excess stress on an engine does not help longevity at all. The 3.0 diesel seems to be the most risky choice, good on fuel yes, solid torque output for towing and hauling, but the engine seems to have the most issues out of all of them with EGR and high pressure fuel pump failures.
I had the 2022 2.7 ho custom, and do to a couple events I ended up trading in for a 2023 1500 LT Z71 5.3. And can honestly say I still respect the 2.7 ho but the 5.3 feels like a way more solid truck. I have some video clips of my 2.7 (I pulled almost max weight and put 7k miles on it before trade in) I plan to do a real comparison for real everyday use and ownership
@@justinh1258 and plenty of people other then yourself have owned and then like them. And you most be a slow learner if it took 3 to make you say they suck. But I only keep my trucks while under warranty so I’m not worried. And you know you don’t have to put a engine down to enjoy the one you have. I’ve owned and pulled max with my old 2.7 ho, like I said I had no complaints with the 2.7. I honestly looked at a 2.7 lt but I don’t like the 8 speed. But we all have opinions.
I have a 2020 Sierra w/ 5.3, seems very good all around and my consistent mpg Ave is about 16.5 , which I think is weak. If I would do it over I’d go w 6.2. The 4 c turbo probably seems cool at first but just sounds like a long term problem that will be very expensive
If GM would have put a 3.5 V6 TT instead of a 4cy T it would be alot more sellable. Just feels a 4cy doesn't go on a Full Size Truck even with power adders
I have a BMW diesel and did a lot of research before taking the plunge. There’s a lot of similarities here. Many people reporting dead vehicles with low miles. To make a long story short - a lot of short trips will kill a modern diesel engine. They need a good hour long hot run at highway speeds periodically to properly complete a regen cycle of the dpf and it just generally seems to do the engine good. So get the engine fully warmed up and then have about a 30-45 minute highway run above 40 mph without stopping. There likely is a way you can use a scan tool to see when the last time a regen cycle was completed successfully. Just sharing lessons learned from another in-line 6 cylinder diesel that now is nearing 200k miles and still puts a smile on my face….
If diesel prices were relevant to gasoline prices at the pump, 3.0 all day.... but they aren't. Diesel costs almost twice as much at the pump where I live, I really don't understand why people are so excited about their 3.0 MPG's. If the fuel costs you twice as much to get you those MPG's, and the engine costs more from the factory as well as the regular maintenance, DEF Etc... Definitely doesn't make much sense to get the 3.0L. Its a simple math equation, cost of ownership over a year(s). I don't care if a truck gets 100 MPG, if the fuel cost is $1,000 dollars/gallon it doesn't really matter does it? You'd have to put on a LOT of miles for the MPG benefit of diesel to make sense financially, much more than average annual mileage for most people. At that point... do you really need a full size truck if you're putting on those kind of miles? 5.3L makes the most sense to me financially, and you're still getting a V8 with capability/sounds good.
I have a 3.0 -used to run 6,2 - will not go back - my 2023 Sierra Denali is due -20 days - Also a 3.0 but significant bump up and torque compared to the one I have now
When talking about the miles per gallon, you really need to do a cost per mile. Yes, the diesel gets more miles per gallon but when you factor in the cost per gallon of diesel and the additives, then it’s a closer call.
Every body always talks about the greater fuel economy of diesel motors but ignores all the other costs associated with diesels. If you do the math, especially including the massive purchase price increase, diesels will always cost you more when you include the other expenses. By a significant margin too. However, if you are towing large heavy trailers frequently, then yes the diesel is the best option. Very few people driving 1500's will ever recoup the money of buying diesels. In fact I bet in 1500's, 99% will never recoup the money.
When I bought my '21 Sierra 1500 with the duramax, the duramax was less than $2500 more than the 5.3. Not to say the fuel economy will make up for it, but it's not the massive $10k-$12k upcharge you see on the heavy duty trucks.
So is the Diesel reliable for up to 200k? I hear it’s more expensive to get fixed. Do you have to do particular things to keep it running and cold start it in winter weather?
Not really, my neighbor has a 2021 and is getting 34 mpg. Even with diesel being $1.20 more per gallon it is 10-15 mpgs better than the others and that will end up being cheaper.
Would this depend a lot on the kind of driving though,i could see it making a difference on long trips etc,does your neighbor do that as that’s great mileage
I’ve got a 2018 Denali with the 6.2 and my twin brother has a 2020 at4 with the 3.0. We both pull bass boats and they both do that no problem. When it’s time to pass another vehicle I’ve got more confidence getting eastbound and down with my gas vs his diesel. Yes, he gets better fuel economy, but my 6.2 has gotten 26mpg @ 65mph on the I40 which ain’t bad and the trade off with premium fuel vs cost of diesel I still come out ahead and if it’s any kind of drag race…
I traded my 22 Raptor for a 23 1500 At4 Diesel and couldn’t be happier. The raptor felt extremely cheap for an 85k truck. Also had a bunch of issues with it. Ford needs to get their stuff together or they’ll be in serious trouble.
I don’t doubt the 2.7 is a good engine, but the fact they put a four-cylinder in a full-size pick up truck just doesn’t sound right imo
I could be wrong but I feel like they mainly did it just for the fuel economy numbers "on paper" as they say. We all know it isn't guaranteed to have better real world MPG but automakers have been putting lower powered, or smaller displacement, engines in some models to improve their fleet fuel economy average. It's also the reason they put auto stop/start in damn near everything. JUST to look better by the numbers.
@@JasonYergin agreed
yeah i agree. They either need a V8 or a diesel i6
What does sound right is that it tows more that the 5.3 and people still think the 5.3 is a good engine😂
@@JasonYergin I remember hearing that the engine was intended for the Colorado, but the development of the third gen was delayed so they ended up putting it in the Silverado and some Cadillacs.
2022 silverado 3.0L diesel I6 owner here, just today I did a run for about 106 miles at around 68-70 miles an hour, got 31.7 mpg out of it, shit’s crazy and so damn smooth cuz of that 10 speed transmission, best of both worlds
I'm planning on picking up 3.0 diesel Silverado as well, I was wondering if you broke it in easy or just drove it normally?
@@Racer18crf i bought it used with only 12000 miles on it.
Besides the 10 speed transmission, I6 engines are well known for their smooth and quiet operation.
That 3.0 diesel has a servicable oil pump belt with only 12 hours of labor to replace it w transmission removal
This is what has me looking at the 3.0. Can do the DD duty with great mpg and towing the race car duty no issues.
5k miles in on my 2023 LZ0 Duramax. It has been absolutely fantastic. I live in Colorado, and that turbo diesel is the way to go to maintain power at elevation. It tows amazingly in the high country, and the fuel economy is otherworldly for a full size
How good is it in cold weather
I love diesels, but with the emissions and the corrosive as hell def. I will never buy another one. Every issue with emissions costs a ton of money. And here's the kicker. 25 years ago you wouldn't even know it happened. Cis that shit wasn't on there
@@codyfarmer1 Yeah the diesel are nice engine for fuel economy and power, but i agree the emission stuff is complicated.

Yea shure Ya do !!!
until you have two engine failures and have to replace the motor at 60k miles.
I bought a 2.7 back in May. Granted its my first truck, but I truly have no complaints on how it drives or performs. I got the six seater and took a family trip and everyone was comfortable. The gas mileage is amazing if you aren't driving like a manic.
Me too, I love it. Turbos and gas mileage are all about how you drive them. I average a lil over 20 mpgs
I had one but traded it in. The 2.7 had no issues other than lag, but why tax 4 cylinders when you can use 8 cylinders to split the workload. PSI and RPM kills engines. To each their own. 2.7 has plenty of power, but I got 23mpg in the city. 16 with the 5.3.
I'm a MOPAR guy but have always loved that 6.2. She's a beast and would be my first and last choice.
Yeah me too love the 6.2 think it's the best non supercharged v8,. That is unless Ram decides to put a 6.4 392 engine. Hello Ram make it and I will buy it.

I e had three trucks with the 6.2 amd and it’s a beast ! 3.0 is great on mpg though. The only downfall of the 6.2 is it has to have 93 octane
I’m gonna go for the 6.2 because of its remarkable performance and sound!!
Yea and Buy all that 93 octane Gas ! You Be lucky to afford the 4 banger !
I have the 3.0 in my 2022 GMC Sierra (refresh) AT4. Have under 7k miles and I average 28-30 on the highway. My best 50 mile range is 34.4 mpg!!! Was going to get the 6.2 but during production they ran out of inventory so I chose the 3.0 diesel; great choice. Love this engine!!
The new diesels are awesome, but the emissions are trash. I personally know 2 people who own them and they'll never waste another dollar on them ever again.
FCK man my personal favorite for the real Duramax obviously the 6.6 is 04-07 when emissions weren't nearly as disastrous, it actually destroys the engines, shuts them down entirely so wtf? Junk!
I have a 2011 Sierra lc9 which is already legendary for bulletproof reliability but! What brings it down? Emissions the EVAP system is/was notorious for always being on, FCKNG bllsht but GM was forced to comply for EPA credits meeting the federal mandate somehow. Just goes to show you can have the most reliable (legitimately with the 11 lc9 5.3 ) yet 1 little "flaw" brings down the entire vehicle. I know how to cheat the system for a sticker but a lot of city boys don't so wtf. And the LC9 5.3 EVAP issues is NOWHERE as bad as the tiny new 3.0 inline 6 diesel, I feel for you man honestly. Do as you wish, as I truely wish you the absolute best of luck no matter what, but dump that whore for a proper 5.3 or a nasty 6.2 they're damn near bulletproof engines still in a world of unreliable Garbage.
Even Honda, Toyota (that never make powerful engines) are having severe reliability issues making a tiny engine push too big a vehicle.
The Honda problem is their legendary 1.5 l direct Injection Turbo, there's so much pressure being forced into the engine that the fuel bypasses rings which dilutes the oil popping them in less than 50k!!! In a dam Honda!!!
Only GM has cracked the code, the 2.0 direct Injection Turbo is reliable but some have in fact had issues but it is accepted as a very reliable engine. The other will copy them, if not already buying GM tech like toyota, Ford, Honda and others lol

Ben remember these trucks run on different fuel. Diesel better mileage but higher fuel cost. 6.2 premium 5.3 87 octane and 2.7 regular octane. More RUclipsrs need to explain this to people
We've put alot of miles on a pair of 6.2s buying 87 octane. You hear the occasional pinging if you listen real close. Fuel economy is about the same as 91 empty. Towing 91 is better i would say.
Agree. Cost per mile is the real key, but isn’t consistent with upgraded fuel having different markups in different locations. For example, diesel is $1.5 more than regular in NC right now.
@@BabyGators This is insanity, how gas can be cheaper than Diesel today, I remember 30 yeasr ago when people consider diesel as disposal waste and cost less than $2 per gallon. hope this not continue for so long.
@@sam79357 it is insanity, but you can thank absurd regulation for the swap in fuel prices. The amount of taxes on diesel don’t help either. It’s a shame because it’s much better, more energy dense fuel.
@@sam79357 $2 30 years ago is around $4-5 today. So your point means nothing when that’s about where diesel is at now
I have a 2019 5.3 8-speed DFM Silverado. So far I really love the truck. In my opinion this engine hits the sweet spot of efficiency, power, sound, and drivability. GM has done a great job of coming up with a lineup of engines that seem to suit the needs of just about anyone's needs. I do like the diesel but between the premium cost to get it, plus the extra cost per gallon of fuel along with DEF fluid and the fact that maintenance will probably cost more than a gas engine, I would probably steer away from it unless towing were the main concern. The 6.2 makes great power but really requires premium gasoline. The 4 cylinder is an interesting option. I would like to see how it fairs for reliability over the coming years.
Transmission will go maintain i have put 2
The 4 cylinder has been around since 2019, so its proven itself already
I hated the 8 speed transmission, would have rather had the 6 or 10. Less than 30,000 miles on my 2020 RST and it started shifting rough in gears 1-3
Have the 5.3 and use it for work will be going the 6.2 next
I’m a retired G.M tech. I test drove the 4 cylinder Silverado and it is a pretty surprising engine.
Exactly, people need to get over the fact that the cylinder count is small. That is light a deep latent bias, that is not really valid when I have seen turbo'd 4's produce well over 500HP. The cylinder count thing changes with technology. Even the heftiest diesels are often just 6 cylinders. And then there is the durability argument. Sure Turbo's run hotter and durability will be an issue, but when, 200,000 miles. Do most people even drive the rigs that long and for that many years? Mostly "no". The Turbo Diesel 3.0L seems to be the sweet spot.
Did you cut your balls off as well?

6.2 seems like a great choice at the surface level but week to week, pumping premium fuel into the 6.2 doesn't seem like a great choice, especially because the 5.3 is a great option and is tuned for regular fuel.

I bought my truck in 2020 so it has 45 more horsepower and 35 more ftlbs of torque. Tow rating of 9800 pounds which is 3000 higher than the 2.7 of 2020. I also don't worry if the open deck design of the 2.7 will handle the 20-30 pounds of boost without cracking the engine block or failing a head gasket.

5.3 with a good AFM delete. Towing package with lower gears to help protect the trans
I'm the proud owner of a 2006 1500 with a pre-AFM 5.3l engine. The thing is rock solid, plenty of power and nice gas mileage. Every time i go to the dealer for an oil change (They often have the best price these days), they offer to buy my truck. They tell me that I don't have to buy anything from them, they just want my truck.
Last time I was at the Chevy dealer a salesman told me they were instructed to push the 2.7 because nobody wants one. It's pretty much all they had on the lot anyway. As for me, I made my decision in 2019 and went with the 6.2 with the 3.42 axle and max trailering package. The thing tows like a beast.
The 6.2 is quite fun also!
I think a lot of people are skeptical of the 4 cylinder engine. Many remember the “Iron Duke” Camaro’s from the 80’s, and assume that the new 4 cylinder trucks are underpowered and virtually useless when it comes to towing a trailer and doing truck things. They’re definitely not underpowered. But Chevy needs to convince people to try them!
My local dealer had six of the 2.7s on their lot when new vehicles were hard to come by. The salespeople were literally begging people to take them. I'm personally less scared of the 2.7 and more scared of the 8 speed that they pair it with.
The 4 cylinder is a brilliant option. What do I mean when I say that? It's for a large portion of people that want a truck but don't actually need a truck. I see way too many people in office parks with top trim trucks that will probably never tow anything or carry anything in the bed more than a small trip to Home Depot.
Also, I currently own a 22.5 AT4 refresh in which the 3.0l is the base option with the 6.2l being the upgrade. But with the lifter issues... I'm good.
If you’re going for fuel mileage, then Duramax is the way to go. I personally have always had the 6.2 L. You can’t beat the sound the feel of a 6.2 L V-8 I just couldn’t bring myself to get a diesel especially with the price of gas and people running out of diesel this year. Great review all good comments but I’ll keep the growl of my V8 😂😂
2.7 HO or the 3.0 Duramax all day for me. I've got a 2022 refresh with the 2.7 HO and its fantastic. Came from a few GM V8s and a Colorado 2.8 Duramax prior to it. The torque it delivers is meaty throughout, and the 5049lbs curb weight (crew cab short box 4x4) more than makes it peppy. Plus engine construction wise its all forged bottom end and tri metal bearings just like its diesel brethren. Your comparison on the 2.7 vs the 5.3 I've had the opportunity to verify on GPS based 0-60 timing. My 2019 old body 5.3 double cab (just shy 5400lbs curb) was good for 6.85 seconds to 60mph. My 2.7 HO (5049lbs) was 6.9 seconds.
In july, I bought a 2020 RST with the 3.0 Duramax with 35,900 miles. I love it. I do a lot of highway driving. The fuel economy is incredible. Im averaging 22-24 mpg all over the northern half of Arizona. I live in the Phoenix area.
The 6.2 Never Fail,No Contest,Unless There's A 3.42, A Max Tow Package With A 10 Speed,l Love The 6.2.
Same here
The one thing that disturbs me about the Duramax is they use a wet belt to drive the oil pump at the back of the engine. The timing chains are also back there.
I'm more interested in the longevity aspect of these engines. I'm a mechanic on a fleet of around 30 Isuzu box trucks with the GM 6.0 engines. Half of which have over 300,000 miles on them. I have my doubts we'd have the same results with them turbo 4 cylinders.
That 6.0 gas was one of GMs best engines ever. Darn near bulletproof. Almost bought a 06 1500 Hd with the 6.0 once. I should have. I’m curious to see how the new 6.6 gas in the 2500 is going to fair long term.
I have the 3.0L Duramax in my GMC and I love it. What I don't love is the check engine has come on three times already in one year of ownership.
Always use #2 diesel and max 5000 miles oil interval.
Additives, additives, additives. If I treat my fuel and oil I don't get the DPF related check engine lights. I used Hotshots EDT in the fuel and FR3 in the oil.
The added emi$$ion$ required by big brother on the diesels, plus gas being cheaper than diesel by about a buck a gallon in the NE, would have me opt for the 5.3. And I’m a diesel lover too.
@@breadn5556, terrible advice.
These modern diesels are all like this. Dealers do a TERRIBLE job of not explaining that they absolutely cannot just be driven around town. If you're not on the highway a lot, or at minimum driving in an area where you get long stretches without a traffic light or stop sign, then you are just asking for DPF issues. And you have to keep the oil changed at least twice as much as the manufacturers say you do...I never go more than 6,000 miles without an oil change.
I switch from the 6.2 to the Duramax 3.0 and I have to say Duramax in a half ton truck has been the best decision GM has ever made! that engine is solid I don't think I would ever go back to the 6.2!
What are some of the noticeable differences
I’ve had 3 F150’s for the past 8 years (I drive a lot for my job so I trade in often) and consistently get 21-23mpg with my 5.0. I’m considering a GM product in the future but man the fuel mileage on the V8’s are pretty horrible compared to the competition, I’d be look at the diesel personally.
I have a 23 Denali Ultimate I just got this week with the Duramax. I like it so far but I don't really have enough time with it to know much but I have had plenty of the v8s and it sure seems I have pretty much always gotten better mileage then what is claimed. I know I get better numbers in my Suburban then what is claimed. Even running flex fuel pretty sure I get better numbers and I am positive you loose like 15-20% economy with flex fuel only reason I ever buy it is its normally $1 cheaper per gallon but the last time I bought it, it was only like $0.25 cheaper. Gas has went up so much the last month here it was $2.99 like 3 weeks ago now its $3.40 range and diesel is only $0.45-0.55 more.
I have a 2018 5.3 and couldn't be any happier with this truck
Hi Ben , big fan of your channel. Here’s a suggestion for a in the future, down the road video. Re-do this comparison test with all four power train options and give a update of j h ow they aged in feel, drive ability, and mileage.

Whatch out for the AFM. It will collapse lifters and possibly roach the cam. Had it happen in my 6.2. Bought the 3.0 this time.

It seems like they put the 2.7 liter 4 banger in some Silverado's just for the fuel economy numbers "on paper" as they say. We all know it isn't guaranteed to have better real world MPG but automakers have been putting lower powered, or smaller displacement, engines in some models to improve their fleet fuel economy average. It's the same reason they put auto stop/start in damn near everything. JUST to look better by the numbers, according to the EPA's official fuel economy rating.
A lot of people are upset over the 2.7's fuel economy. And what I mean by that is that there's a class action lawsuit brewing because the promise of 20+ highway has generally been unmet. Which is pretty sad because the 5.3 actually can, and will last 3 times longer as long as you defeat the cylinder deactivation. I suspect the real reason for its existence is as an insurance policy for when diesel fuel becomes prohibitively expensive and/or unavailable over the next few years.
Better emissions is the only benefit. But I'll take my 6.2 any day of the week.
Bought a 22 Silverado and got the 6.2 and I couldn't be happier. I was tempted by the diesel but I love it
I test drove a 2.7 sierra a couple weeks ago. Wasn't impressed. Turbo sounded like a Jetsons car so I wonder if all was working right. Heard a tapping with revs... Couldn't tell if it was injector noise or lifter noise. Either way, it didn't do anything to convince me it was worth any attention. Real world mpg isn't much better than 5.3, often worse. Towing mpg is easily beaten by every other engine option. Extra complexity of a turbo makes me worry about long term reliability.

My particular 8 speed in my silverado though.....it feels kind of clunky from 3 down to 1st when stopping. It also feels that when I am in traffic, it lurches a bit around d 2nd to 4th? Not sure, it's new to me compared to my 02 silverado and my 08 tahoe, both with 4L60s.

I have the 5.3 but installed Pulsar LT to disable DFM AFM. Straight 8 all the time. The gas mileage sucks but it’s got all the power I need. Can spin 33s no problem
2022s, 5.3 do not have DFM…6.2 does
I went with the (GMC) 5.3L. This was after owning the 6.6L Duramax in my 06 2500HD. Honestly LOVED that 6.6L and if I thought I'd do even half the towing I used to, I would of gone with probably the 3.0 Duramax. I'll admit the spike that Diesel took also scared me off.
What a waste of money. Rolling pile of crap.
Return it or sell it. Lifter will go out before 100k and kill your engine
Price,horse power,fuel mileage. . Take your pick ... Price is it for me. Fuel ,insurance, cost of ownership... 2.7lt RST thanks for the comparison.
Good review when I first thought of a new 22 Silverado I thought of getting the 2.7 after having 2 previous 5.3 but the fuel economy wasn't really any better than the 5.3. In Canada the 5.3 is about $2k over the 2.7, the 3.0 is about $700 more than the 5.3 but if you factor in that it comes with a block heater which is a $195 option on both the 2.7 and 5.3, $500 more is a no brainer to get the 3.0. My 22 order was never picked up but got a 23 with the LZ0 time will tell if it's as trouble free as my previous 5.3' s were but agree it's probably the best all around power train in a half ton pickup right now.
What is your fuel economy in Canada with the 5.3
Diesel for MPG‘s and if you’re driving a lot, 6.2 for fun, 5.3 maybe best overall and 2.7 for low cost and low emissions. If you’re worried a about lifters, first or last.
The days of charging msrp are about to come to an end.
They already have. US car manufacturers are about to have a very very rude awakening. 2023 will be one of the worst years on record for GM, Ford & Dodge.
@@leftycosta1899 Unfortunately for the consumer gm has finally figured out the law of supply and demand. They are no longer flooding the dealers lots, keeping supply low keeping them from throwing money on the hood to move inventory.
21rst 6.2 extended cab with the performance package. Absolutely love the truck!!!
My husband is a Chevy guy. We currently have a 2021 with the 6.2. We were Leary of it as we alway had the 5.3s. What I can say is our 6.2 gets better gas mileage than our last with the 5.7. The 10 speed transmission does make a difference. We have been pleasantly surprised!
What mileage do you get?
@@ktpinnacle on a recent trip to the coast we averaged 24 mpg. Around town around 20 mpg. We had an Avalanche (2012) that we loved with the 5.3 and were lucky at times to get 20 on highway trips. 17 in the city.
@@loriguinan2206 Really impressive for a 6.2. No lead foots in that family. My 2001 Yukon has a 5.3 that I have to hypermile to get 17 on the highway.
Yep def you should see how good mpgs can be with 5.3 with dfm. Pretty good for a crew cab truck and running 87 octane.
You can thank Ford for that 10 speed
How are they putting v4 to full size but not v8 to colorado size.
Not a v4
Great video. Do you think the DFM is responsible for the lifter issues the 5.3 and 6.2 have been experiencing?
Could be
Definately, happened to a family members 2022 GMC with the 6.2, it only had 36,000 miles on it.
The guy works for a Chevrolet dealer. He's not going to tell you anything negative about the product if he wants to keep his job. Duh.....
@@wesfudge Thank you for clarifying that for me.
after watching mechanic reviews of the duromax, especially the fact that engine is set basically backwards where all the maintenance issues are on back of motor, and the fuel pump will need replacing every 100k,, and Def, and diesel costing an average of 50 cent more plus the fuel filter cost,,, I m sticking with V8 gas 6.2
I'm pretty satisfied with my 5.3...I know it's basically the same as the one from 2007, but the 10spd really improves the drivability. That said, I didn't have many options available when I bought it last summer. If I'd had I suspect the 2.7 would be in my garage now. I'm trying to not find an excuse to drive one as long as I'm happy with the 5.3! 😆
Same experience for me, went from 5.3 8spd to 10spd and it’s AMAZING how different the trucks feel.
@Matthew B what year was your 5.3 8 speed?
Pretty sure the 5.3 has had a bump in hp and tq since 07 though.
MY 07 and my 13 Silverado with the 5.3 both used oil like I owned a well. 2-3 quarts between 5000 mile oil changes. The dealership told me that was normal oil useage. Now I drive a Toyota Tundra.
Wow..had my.04 5.3 for 12 yrs. Dosent burn any oil,or.leak..4 speed trans.. wonder how the 8 speed would work with that.
I have a 6.2 and a 3.0. I wouldn't recommend the 3.0 for your average short trip grocery getter. The 6.2 is really fast and it sounds great with a cat back. The 10 speed in my 3.0 grenaded at 54k. I run the 3.0 as a work truck, it gets a 150+ miles a day and idles all day. It's perfect for that.
Heard there’s problems with the diesel engines so I ordered a 6.2 with my new high country 👍🏻
Every engine has "problems" arise. Not sure the Duramax has many issues. They did a revision to make it better but none of the reported issues were big. The 6.2...if I am not mistaken may be in a class action suit for lifter issues. Could be the 5.3 as well? But if true...thats a "problem"
Good choice
One question that might be a good point about this motor on GM trucks is range. If range matters and GM still hasn't kept up with the competition with a larger fuel tank offering, this is the only way to get a longer range. So, if that matters, this is another benefit and/or factor in the ROI discussion
Love my 6.2 but unfortunately everyone must install a pulsar Lt to feel the power. I've had it for over a year and it is a rocket.
Or just drive it in L9 instead D (in fact I'm doing this for 6 months now. I can feel the difference when I shift back to D to drive short distances)
The Pulsar LT is a nice tool for throttle sensitivity. But a tuner will give you that same option while actually adding power. I love my Superchips tuner on my '21 6.2 Trail Boss!
@@craigstark2712how much horse power did you gain, I've dealt with tuners a bit before with mixed reviews.
@@thorpower1015 they claim up to 45 horse to the tires in the mid range on 93 octane, peak about 17 horse. I don't have 93 around here so around 35 horse for me. I can definitely feel the difference though!
@@craigstark2712 cool I may check it out
Ive had an 09 Denali with the 6.2 AWD and i cant imagine having any other powerplant. Im in the market for something else right now and not looking for anything other than a 6.2. Hell of a good engine. Right before they put AFM b.s. in em.
Spent 3 years driving my 2020 with the 2.7 and never missed the V8. In over 22k, the truck averaged 20.1MPG total. New 23 is also a 2.7 but the extra 82flbs of torque are immediately noticeable. For me, with the current price of these trucks, the deals on the 2.7 were an easy choice. That being said, I lease so no warranty issues but I would be concerned about long term ownership. Also, the reprogrammed 8 speed trans is definitely improved over the 2020 version.
The v8 will almost the same mileage. Much more reliable and long lasting
@@freedomliberty7611 I agree, but I'm leasing it. I saved about 3K because it's the turbo.
@@jnmcs You didn't save anything. Leasing guarantees you will have a car payment forever. You are burning money to borrow a vehicle.
My V6 Toyota SUV gets 28 mpg average, 30+ on the highway. These smaller engines are cheaper to produce, get worse gas mileage and will die far sooner than a proper V6 or V8.
@@tx611 Opinions vary.
@@tx611 Your Toyota is junk though, just like you.
What happened to the 4.3 V6?? I have one in my 2019, very satisfied with it!
I just bought a 2023 Silverado RST with the 5.3 V-8. I Like the 10 speed and the fuel economy.
Picking up a 22 high country 1500 5.3L tomorrow!
Duramax makes sense for this type of vehicle.
The LT based small blocks (6.2 & 5.3), despite the DFM lifter issues are the most solid choices for the average person. The 2.7 is a solid engine but towing or hauling it would be pushed to its limit, excess stress on an engine does not help longevity at all. The 3.0 diesel seems to be the most risky choice, good on fuel yes, solid torque output for towing and hauling, but the engine seems to have the most issues out of all of them with EGR and high pressure fuel pump failures.
I tow with it everyday, stop fucking lying to people
I love my 2.7, plenty of power.
lack of power and shit for fuel economy
I traded my 2018 5.3 Chevy to a 2018 6.2 GMC. Love the power in the 6.2.
6.2 💨💨💨
I had the 2022 2.7 ho custom, and do to a couple events I ended up trading in for a 2023 1500 LT Z71 5.3. And can honestly say I still respect the 2.7 ho but the 5.3 feels like a way more solid truck. I have some video clips of my 2.7 (I pulled almost max weight and put 7k miles on it before trade in) I plan to do a real comparison for real everyday use and ownership
The 5.3 sucks
@@justinh1258 lol
@@tattoomagic6110 lol all you want, I’ve owned 3 of them
@@justinh1258 and plenty of people other then yourself have owned and then like them. And you most be a slow learner if it took 3 to make you say they suck. But I only keep my trucks while under warranty so I’m not worried. And you know you don’t have to put a engine down to enjoy the one you have. I’ve owned and pulled max with my old 2.7 ho, like I said I had no complaints with the 2.7. I honestly looked at a 2.7 lt but I don’t like the 8 speed. But we all have opinions.
@@tattoomagic6110 I’ve never had major problems with a 5.3, it’s an old and underpowered motor made unreliable and worse by afm. Cope
Awesome video this helped me decide on which size pickup I'm going with, thanks for the video review.
I have a 2020 Sierra w/ 5.3, seems very good all around and my consistent mpg Ave is about 16.5 , which I think is weak. If I would do it over I’d go w 6.2. The 4 c turbo probably seems cool at first but just sounds like a long term problem that will be very expensive
viking guru
I have the 1st generation lm2 3.0 duramax 277/460. I regularly see 30+ mpg's
(32 -37) on the highway cruise set @ 70mph.
If GM would have put a 3.5 V6 TT instead of a 4cy T it would be alot more sellable. Just feels a 4cy doesn't go on a Full Size Truck even with power adders
I love my 2024 ltz 5.3 feels a crap ton more powerful those 10 speeds put in work
6.2 with the Borla Atak cat back = 😁
Loved my 6.2 L Trailboss
U don't buy a truck for fuel economy!
New to diesel, but I'm guessing the GMC 3.0 duramax is the same as Chevy 3.0?
Thinking about getting the GMC 3.0 1500.
6.2 >>>> ALL
I have a BMW diesel and did a lot of research before taking the plunge. There’s a lot of similarities here. Many people reporting dead vehicles with low miles. To make a long story short - a lot of short trips will kill a modern diesel engine. They need a good hour long hot run at highway speeds periodically to properly complete a regen cycle of the dpf and it just generally seems to do the engine good. So get the engine fully warmed up and then have about a 30-45 minute highway run above 40 mph without stopping. There likely is a way you can use a scan tool to see when the last time a regen cycle was completed successfully. Just sharing lessons learned from another in-line 6 cylinder diesel that now is nearing 200k miles and still puts a smile on my face….
If diesel prices were relevant to gasoline prices at the pump, 3.0 all day.... but they aren't. Diesel costs almost twice as much at the pump where I live, I really don't understand why people are so excited about their 3.0 MPG's. If the fuel costs you twice as much to get you those MPG's, and the engine costs more from the factory as well as the regular maintenance, DEF Etc... Definitely doesn't make much sense to get the 3.0L. Its a simple math equation, cost of ownership over a year(s). I don't care if a truck gets 100 MPG, if the fuel cost is $1,000 dollars/gallon it doesn't really matter does it? You'd have to put on a LOT of miles for the MPG benefit of diesel to make sense financially, much more than average annual mileage for most people. At that point... do you really need a full size truck if you're putting on those kind of miles? 5.3L makes the most sense to me financially, and you're still getting a V8 with capability/sounds good.
In Utah diesel is a little more than gas. No where near double.
I have a 3.0 -used to run 6,2 - will not go back - my 2023 Sierra Denali is due -20 days - Also a 3.0 but significant bump up and torque compared to the one I have now
When talking about the miles per gallon, you really need to do a cost per mile. Yes, the diesel gets more miles per gallon but when you factor in the cost per gallon of diesel and the additives, then it’s a closer call.
Every body always talks about the greater fuel economy of diesel motors but ignores all the other costs associated with diesels. If you do the math, especially including the massive purchase price increase, diesels will always cost you more when you include the other expenses. By a significant margin too. However, if you are towing large heavy trailers frequently, then yes the diesel is the best option. Very few people driving 1500's will ever recoup the money of buying diesels. In fact I bet in 1500's, 99% will never recoup the money.
You’re forgetting the diesels have higher resale value than their gasoline counterparts
When I bought my '21 Sierra 1500 with the duramax, the duramax was less than $2500 more than the 5.3. Not to say the fuel economy will make up for it, but it's not the massive $10k-$12k upcharge you see on the heavy duty trucks.
I ordered a Denali Ultimate a month ago and the 6.2 is a $995 option, the diesel is cheaper in the higher trim levels.
So is the Diesel reliable for up to 200k? I hear it’s more expensive to get fixed. Do you have to do particular things to keep it running and cold start it in winter weather?
The price of diesel and the price for the engine is probably prohibitive compared to mileage ?
True
The 3.0 is actually the cheaper engine, it’s a ~$995 option for the 6.2 in the higher trim levels.
Not really, my neighbor has a 2021 and is getting 34 mpg. Even with diesel being $1.20 more per gallon it is 10-15 mpgs better than the others and that will end up being cheaper.
@i did that”
Would this depend a lot on the kind of driving though,i could see it making a difference on long trips etc,does your neighbor do that as that’s great mileage
I’ve got a 2018 Denali with the 6.2 and my twin brother has a 2020 at4 with the 3.0. We both pull bass boats and they both do that no problem. When it’s time to pass another vehicle I’ve got more confidence getting eastbound and down with my gas vs his diesel.
Yes, he gets better fuel economy, but my 6.2 has gotten 26mpg @ 65mph on the I40 which ain’t bad and the trade off with premium fuel vs cost of diesel I still come out ahead and if it’s any kind of drag race…
I traded my 22 Raptor for a 23 1500 At4 Diesel and couldn’t be happier. The raptor felt extremely cheap for an 85k truck. Also had a bunch of issues with it. Ford needs to get their stuff together or they’ll be in serious trouble.
Same but traded my raptor for a TRX
What about the notorious transmission shudder with the 8 speed? I have that issue off and on in my Colorado.
