@@chargerscatslim6711 it’s bc if you break boost the 10 speeds the tranny lags, throw it in 4x4 and sport mode and press the gas from a. Stand still it will launch so much harder
@@danielstacy4788 that's about what I get with my 6.2, buddy of mine gets about the same with a 5.3. The only difference is the 6.2 recommends premium gas, which is a little more expensive.
@@danielstacy4788 same here, put a corsa exhaust on it when I got it. One of the best exhausts I've heard, kinda like it better than my camaro exhaust.
In a PERFECT world I would like to have gotten the 6.2 but, I'm honestly happy with my 5.3... and you're right the10 spd makes a big difference. my 16 had the 8sps.
I agree! I was at a Toyota dealership and found my 2017 GMC Sierra SLT 5.3L as a trade in there. Was the only GMC on the lot and I love it. If I was able to choose which engine came in it, I'd have taken the 6.2 but the 5.3 is great as well. Maybe I'll procharge it at some point and make up that extra power lol. But mine came with the 8 speed which is great, has a sunroof, heat/cooled seats, etc. Practically every upgrade you can think of. Big upgrade from the things I've owned before haha. And I'm only 22 so there's plenty of time to upgrade later.
It's cheaper to add a turbo or supercharger yourself. I have a modest turbo and some tuning on mine, and pull 12 sec quarter mile times at just over 120mph.
@Boguardis Maybe. I had a 1 of 1 2010 6.2L Z71 shipped to a North AL dealership, where they installed an Edelbrock supercharger at the factory, tuned literally everything to what they called 'perfection,' making right at 840whp, and it lasted only 47K miles. And, it honestly had an easy life. We put in a brand new motor, and I installed a Paxton, and a canned tune, and she has 288K miles on her, and still jerks this camper and bassboat around like they are empty balloons. Haha. Almost 300K miles, and still rocking right at 750hp. Not too bad.
@Boguardis Oh, and for clarification, my 12 sec truck is a 2021 6.2L on 35s. 😅. Just once, I'd like to put on some slicks at the track, and see what it can really do, but my conscience says something will break. Haha.!
One of the BEST side-by-side comparisons I've watched on RUclips, bar none! You've given me some great info to consider as I decide on the engine for my next Z71 Tahoe/Suburban.
GREAT video...nicely done. My last two GM trucks had the 5.3L. My new truck (2021 GMC Sierra AT4) has the 6.2L. BIG difference. It also has a CAI, Borla muffler (flapper delete), Pulsar LT, and stock wheels (with one size taller Bridgestone Revo 3 A/T tires). No added weight with the tires. I call my current AT4 "a Corvette with four wheel drive". I didn't buy it for fuel mileage, or being in the slow lane. 91 octane is good. 93 octane is hard to find here in Oklahoma...but, it is def better. Thanks for doing an excellent real world video comparo. The 6.2L (to me) is the way to go and brings a smile to my face every time I wanna drive like Dale Earnhardt Sr.
Which Borla muffler do you have? I'm thinking straight pipe in the 22 Trail Boss 6.2 I just got! Keep the resonators on of course for drone. I'm down by Texoma and can't find 93 fuel anywhere.
@@yustinaaron - Congrats on your new truck! I have the Borla ATAK muffler (and flapper valve removed). It is "alright" with some highway drone. Prob better/cheaper to do a straight pipe/muffler delete...but, to each their own. As for finding 93 in Oklahoma...good luck! Texas, Arkansas, Missouri, no problem. I find the "winter blend" Shell 91-octane pretty decent. I have run 94-octane (VP racing fuel here in Oklahoma City) -- def fun. But $5+ a gallon.
@@yustinaaron -- Best $500 I ever spent. No, it doesn't void the warranty (Pulsar says to remove it before taking a truck into a dealer for warranty work). Also, leaves no bread crumb trail. Yes, I have mine set on "3" and it is fun!
@@blast4me754 the 6.2 is literally over a second faster in the quarter mile and 0-60 which is huge in performance. 6.3 seconds vs 5.1 and 15.2 vs 14.1. The first day I picked up my Escalade, me and my gf were driving in separate vehicles and she was in her 2018 5.3 sierra ..she was pissed because I kept walking away from her on the highway lol…no, you don’t need the extra power, but it’s plenty noticeable.
Dude! This is such a great video! I've debated myself on the merits of the 6.2 versus the 5.3 . Wow, this is very informative. 6 2 is the way to go if you want performance, and, if you can afford it, is the better choice. It performs better, it sounds better, and has a much more visceral experience while going up through the gears. And a 13.86 is an awesome quarter mile time for a truck! Very competitive. Kudos to you for this video. And kudos to Chevrolet for still offering a large displacement V8. And for raising the top speed governor on these trucks to 112 mph on 2021's and after! Yeow!
I have a 5.3 2018 sierra with the 8 speed. How much did you pay for the engine swap? Including the engine what was the total price? This 5.3 is reliable but it's just not as fast as I want it to be lol.
This is the case in my 5.0L F150 as well. If you try to brake torque it, it actually feels like it bogs or doesn't give power for a split second when you mash it.
I have a 19 6.2 high country with 22inch rims. I had a 17 5.3 and I can feel the difference. Purchased the truck used but the drivetrain (motor, camshaft) had been replaced. Engines brand new lol I’m basically breaking it in right now. I’m happy with the vehicle
Totally agree. The 5.3 is a good solid engine (but do frequent oil changes, don't go below 30% oil life). That being said, I got my 2019 AT4 with the 6.2 because... Just because. It's badass!
@@alexs.5675 Yeah. The issue is the way the oil flows over the top of the heads from the rear of the engine. Eventually the valves start sticking until eventually you have a valve failure. PITA to replace. Not devastating to the engine (you will lose that cylinder), but really tough to get to.
Yeah, the lifter issues were bad for MY 21-22. If you have one of those, consider contacting your dealership before the engine goes kaboom. Before or after should be fine. They changed their lifter design, and then went back I understand.
I might be the only one saying this but I MUCH prefer the look of your truck with the lightweight wheels and tires. It probably performs better in every conceivable scenario with the smaller tires as well.
Great review, I have an ‘18 5.3 6 speed that’s just my luxury daily driver. But my son’s’19 5.3 8 speed is a world different. Smoother, faster, quicker & 25 mpg driving across country!
Count your blessings you have the 6 speed. GM has a huge issue with 8 speed, very unreliable. Pay attention to shifting in your 6 speed. These transmissions have weak torque converters. They slowly come apart and metal filings will get into the solenoids causing occasional hard shift when slowing down. Once you notice that, immediately change out torque converter. You have roughly 6 months till transmission fails from that point if you don’t change out the converter. GM rebuilds are around $5000. 8 speed is even worst. More prone to failures.
great video, thanks for sharing. 1 second faster in the 1/8th mile is a big difference. I live in Wyoming and the elevation here is 7,000 feet above sea level. I've been wanting a Chevy with a 6.2 LS/LT engine for a while because of the power difference between the 5.3 and the 6.2 and this illustrates that perfectly.
Can't tell you how much I appreciate these videos. I ended up buying a 5.3 and while waiting for it to come in I saw this video. Ended up breaking the contract and getting a 6.2l and man I'm glad I did. These videos saved me
Awesome video, I got the 5.3L for a steal and added a Magnuson TVS-1900 and pretty much took care of power difference between them. The 6.2s are harder to come across but the price difference really isn’t bad between them if you find one.
@@Sabertooth_54 City 18-20 with highway 23-28mpg That’s the reason I chose the Mag was because the gas mileage I was told wasn’t really going to change. At cruise there’s like a 1/3hp parasitic loss because of cruising bypass valve. I do need a better Trq converter however in the future lol
@@mikerdz75051 The other considerations taken were the driveshaft (OEM is thin with a 115mph critical speed failure) and the transmission is next on the list. Unfortunately GM made the torque converters and transmission pumps very poorly in general so replacing is guaranteed. These components are cheap for GM and will fail as mine has begun to do. I do wish I’d have changed the torque converter earlier on but it’s a gamble if the trans pump fails.
I had a 16 silverado 5.3, 6 speed i loved it. I tuned it with black bear performance, and I installed long tube headers. i also made it E85, CAI, and deleted the auto shut off. It's such a sweet truck it was night and day after those mods
6.2 is great, I used to have one. I have a 5.3 now, and I’ve had several, and for me it’s plenty. Runs great, enough power for my needs. I don’t really lust for the 6.2. Call me crazy. Maybe I’m just getting old and boring.
My 2018 Tahoe has a 5.3. I believe 3.73 rear end. It has a 6” suspension with 33x12.50 ….. maybe its just me lol but i feel like the truck moves. Im very happy with it. No problems catching up with traffic, merging on to highways etc
I have been very fortunate with GM! My 04 z71 with the 5.3 is still running like a top. Original everything except for plugs, wires and coil packs and runs like a scalded dog. Also very fortunate with my 15’ Denali with the 5.3. I have 6 inches of lift w/ 35’s and 26’s and can absolutely roast them down when I turn the stabilitrack off and it’s stock besides putting .410 gears front and rear. I also love the 6.2 but the 5.3 to me is one of the most well built engines/blocks ever produced
@ I agree with you for sure. The 14-18 5.3’s have lifter issues bc of that flex fuel 4 cylinder bs and the transmissions are GARBAGE!! Two easy fixes tho. AFM/DFM disabler and the updated trans temp sensor. Factory trans temp sensor kicks on at 194°…that’s just shy of boiling and cooks the trans fluid and wears it out prematurely. New one kicks on at 154°. Factory trans fluid in the 14-18’s is also trash!!
Great Video! I think the reason they raised the price so much for 2022 on the 6.2 is because they need money to pay for all the 2021 engines that had to be rebuilt!!!
With the +/-1mpg difference it was a no brainer for me. 2020 TB with the 6.2l is quick. Most everybody who gets in is shocked how fast it is... Love it!
@@ripperlipper1016 I got a 2011 coyote mustang. Thats the only reason why i didnt get the f150. Wanted to try something different I guess. The v6 with afm in the chevy isn't my cup of tea. But it does the job for now.
I engined swapped my 15 Chevy from a 5.3 to a 6.2 with stage 3 cams(including pushrods lifters springs and valves)long tube headers,3600 torque converter,and dyno tuned made 610 hp and 451whp it sounds like and launches like a beast
I have a 2020 sierra 5.3 x31 elevation zero problems! gas mileage is awesome. I have 22k miles on it. used regular gas from the beginning. I have never felt my truck is underpowered. the 8 speed is awesome zero problems. happy i went with the 5.3.
I'll pretty much say everybody with the 5.3 would rather have the 6.2 in a perfect world. If I told you the 5.3 is just fine (which it is) doesn't mean they wouldn't rather have the 6.2. I do have the 5.3 and it is just fine but..... would rather have the 6.2. My brothers ecoboost is amazing as well but i like v8 push rods . But I am old
I drove both and the 6.2 needing premium and being terrible on fuel i opted out. Getting 10mpg with the 5.3 until it got some miles on it was bad enough. Personal preference but if you cant pass someone in a 5.3 with a 10spd the 6.2 might not either.
Great comparison video. Straight to the chase and informative. Would LOVE to see a similar idea but comparing your 6.2 to a newer 5.0 f150 or 5.7 ram 1500
5.7 would get slaughtered, its closer to a 5.3 in terms of performance than it is the 5.0/6.2. The 5.0 vs 6.2 honestly seems to depend on the driver they are really close.
I had a new gen 19 ram with 5.7 and 3.92 gears and it ran a 9.25 in the 1/8th for comparison, My 5.7 tundra ran a 9.54, My stock 2017 2.7 ecoboost ran a 9.04 and an 8.32 tuned, stock 2020 3.5 ecoboost ran an 8.91 and tuned ran a 7.79, and my stock 98 ls1 auto camaro ran an 8.89.
Looking to pick up a 2021 AT4 with the 6.2 this week. Nervous about filling the tank with at least 91 octane going forward. Its gonna be fun, but pricey.
That's really good. I have a 71 Camaro and your truck is right in par with it. I have about 330hp in a 3,400 car and my best 1/4 mile on street tires was 13.8@99.15 mph w/2.00 60ft. Granted, I only paid about $4,000 for that car back in 2004 so I can't complain too much. 😎👍
@@trashbandit2449 LoL Thanks 👍 I was just happy to be able to drive it home. There was a lot of sketchy stuff done to the car I didn't even know about until after I started to fix the obvious stuff. I guess I forgot to add, that 1/4 mile time was back in 2004. I haven't had the car back to the strip since then.
I had new 5.3L Silverados in 2008, 2012, and 2016. I bought a new 2019 with a 6.2L. The 6.2L get better mileage than the 3 previous trucks. The required 93 octane for the 6.2 costs 20% more, but it gets about 10% better MPG than the 5.3's. Probably due to the 10 speed transmission.
I still can’t see the value in the 6.2. At the end of the day it’s still a truck, not a sports car. You’ll pay more for the engine option and here in eastern PA you’ll pay .80$ more a gallon. It’s not apples to apples. If they both ran in the same fuel, then I’d talk. With the 5.3 truck it weighs just a hair over 5k pounds and has 355hp, that’s not weak like most of you guys are saying.
@@chrishansen7004 the ford 5.0 makes 395 horsepower stock, and the 5.3 makes 355, the difference is negligible. I've seen many stock chevy 5.3s keep up fairly well with ford 5.0s and beat Ram 5.7s easily. And the 5.0 requires 93 octane like the 6.2, but will still get mopped by a 6.2, meanwhile the 5.3 you can run on e85.
Drive ability for me. I had a 2009 5.3 then a 2012 Denali with the old 6.2 and I had a 15 5.3 and now a 2020 with a 6.2. I prefer the 6.2 just for the feel. I don’t have to be racing around which I don’t it just feels better. Takes less throttle and doesn’t feel as pokey. Also when I go to merge onto the interstate or overtake a slow moving vehicle it feels better to have more power. I agree though technically the 5.3 isn’t really slow it’s actually putting up numbers “sports” cars did years ago.
I had a 2017 Silverado crew cab 4x4 LTZ 6spd auto with the 5.3. It was good. But it always felt like it needed more. I put an cold air intake on, tune & a exhaust system. Better, but still seemed a little lacking.... Now I have another 2017 Silverado crew cab 4x4 LTZ with the 8spd auto & the 6.2l. Much much better overall. It is noticeably faster but surprisingly it gets slightly better fuel economy than the 5.3. I'm guessing the 8 vs 6spd has to help, but it is just a way better experience now. Imo it is a very worthwhile option if your in the market.
I appreciate your vids. I got the pulsar because of YOUR vid. I have the pulsar intake also because of YOUR vids. I appreciate your knowledge and experience, thank you. I have the 6.2 custom 2022 trail boss...I LOVE IT
Don’t know about that. I brought a brand new 2021 5.3 RST and within the first year the engine lifters failed. Had them replaced but still did not feel good about the truck. Traded it in for a 5.7 tundra. Love the look and design and comfort of the Chevy Silverado but the reliability sucks.
I have the 2022 refreshed Z71 Trail boss LT midnight edition with a basically 7 foot bed, and I love it! My truck runs great for personal use, for work, and off-road. If I needed more power, I might get the 6.2, but I can also do some upgrades that will give me that power.
I have a 2020 5.3 Silverado with a 63 series K & N cold air intake, D.F.M. shut off, Flowmaster Outlaw series 3 inch dual exhaust, 2WD, JET Pro Tuned Mass Air Flow sensor and the thing launches. Definitely not the same setup as your 5.3, but just giving props to what the 5.3 is capable of while still keeping some fuel economy.
I have a '19 Sierra Denali 6.2 with CAI, exhaust, 22" wheels, 275/50 tires. I got 22.5 mpg (trip average) on an 85 mile 65-70 mph highway trip climbing 1600 ft elevation (~4700 ft-> ~6300ft), passing a few people, full bed, full tank, with wife and 3 kids, and then 28 mpg (trip average) on the way back all on 91 octane. I also pulled an 8,000 lb travel trailer 20 miles (flat no change in elevation) and ended with 16 mpg (trip average) on 87 octane (would have used 91 if I knew I was going to tow). This morning on my way to church 6.5 miles away (flat) my trip average was 24.1 mpg and 25.1 mpg on the way back and there's 7 stop lights, 2 stop signs, and a roundabout with 35 - 50mph speed limits (87 octane). So glad I got the 6.2. I wrestled with getting a truck for years, for fuel economy and practicality reasons, kept trying to cram everything into our SUV that I could get 25 mpg - 30mpg. I have zero regrets now.
Ended up with the 5.3 and it is a good motor but I still remember the 6.2 that I test drove. If I could have found the configuration I needed with the 6.2 that’s what I would rather have had. Though I am glad I don’t have to run 93. Great vid!
I have had the 6.2 in every truck I have owned since it was offered, and I never run 93. No issues in any of them, my wife's Denali will ping a touch in high heat but she does not drive like me, so have not worried about it as all oil samples are in-line.
@@trooper5157 I run 87 exclusively unless it is from a hole-in-the-wall gas station. I try to avoid that happening, but when it is unavoidable, I will run the mix of high/low grades in most of south TX, which results in 91 advertised, but I think it is closer to 90. The oil reports for both current 6.2's wear metals are as expected for the mileage. I know both are likely down on power (some timing pulled), but they have so much more torque than the 5.3; even using 87, there is really no comparison. My truck does not show the same higher heat load ping as the Denali. I am guessing the weight of the SUV is playing a factor there.
I've never put 91 in my 6.2. Runs great. 24000 miles on a 2021. From full weight towing to just normal driving. Got mechanic friends that work on them Everyday and swear the 91 isn't needed. I'm a believer. Love my 6.2. It does haul@$$
It just pulls a lot of timing so youre not getting near the power available. It would knock bad otherwise. I wouldnt tow with it a lot like that. Science
I'm currently on my 4th 6.2 now, almost always run 87, maybe a tank of 91 every once in a blue moon if I just got paid or something but I've never really noticed a difference. The yukon and sierras I've had all made it well over 100k without any pings or other issues besides the 8 speed that shit the bed around 170k but that's got nothing to do with octane. My dad was a chevy mechanic for decades and always told me it was a scam unless you've got a vehicle that knocks without it. My '72 c20 on the other hand...
@@carterantebi8776 Yeah it will run on 87. Just very decreased power and the mileage to go with it. Its about science. Very high compression with low octane means a lot of pulled timing which decreases power. Couple that with towing, pulled timing, low rpms its just not what it was designed for. Direct injection only helps so much
Thanks for this video! I traded my custom 19 trail boss 5.3 for a 21 custom tb 6.2 10 speed. (Actually got the new one for 44,500) and traded the 19 for 43,500 lol) I clocked my 6.2 at 5.08 a month into owning it. Much lighter due to less options compared to the LT. Love these trucks.
You did a great job comparing the two..not hating on your truck but it looks new again with the factory wheels on it..love the bull dog look with factory wheels and little bigger tires all within the confines of the wheel wells..I love wide wheels and big tires but late model trucks have wider tracks than older trucks and to me they look right just adding bigger tires and leveling them, they just look newer longer
I can't lie from MY perception you drove your truck more aggressive than the other plus there are mods done even exhaust makes a difference in performance but all in all great video‼️
Owned the 6.2 and it was a great motor. But I don't miss having to put 91 octain in and the 5.3 consistently get 2 mpg better. To be fair the right foot could have been a little heavier with the 6.2 😂
On longer trips I have found the 6.2 gets awesome mpg. On one 100 mile trip with a tail wind I hit 29mpg avg in my Denali. avg I get about 24 if I'm gentle.
@@foxwithshades7080 I just don't like doing so being that it's a direct injection engine and it also has to compensate timing and other things due to the lower octane fuel. Edit: what do you get for mpg?
I was a BIG 5.3 Fan, However bought a sierra with a 3.0 Duramax, and I love it. Yes it has issues, Long crank and 150K oil pump belt. But I've had ZERO issues with it and now have over 20K on it. About to change fuel filter with next oil change.
The worst thing about the 6.2 is the recommended 93 octane. Mine definitely prefers 93. Lose on acceleration and some fuel knock with 87. Other than that they are great.
I recently test drove identical Trail Boss's, one in 5.3 and 6.2. after putting my foot too it, I opted for the 6.2. Later I learned that the sales dude set the 5.3 in normal throttle mode and the 6.2 in sport. Regardless, the 6.2 is a monster after 10 years of driving me 4.7 Tundra. As far are fuel economy goes, I commute around 45 miles each way on hilly 2-lanes running 87 octane. The 50-mile average MPG is just shy of 17. I ran a couple of tanks of 91 octane as we don't have 93 in my area. I didn't see a noticable difference. At least not enough to justify the extra $ at the pump.
Be careful running 87 in a 6.2, I did 87 and 93 about 50/50, had a bad engine misfire after putting 87 in one day and was told that can happen running 87. The CEL stayed on until I ran the tank empty, put in 93 and it almost immediately went away.
@@rook3364 “from what I heard” Then you don’t actually have any experience. Got it. The manual states it can run on 87. Straight from GM. Typically I’d put 93, but on occasion I’d put 87 to compare mpg and performance. In my SS I never put in anything below 93, but you’re not driving a 6.2 truck like an SS camaro. Especially on the highway
I have the 6.2 in a Black Widow Chevy 1500. With the upgrades in HP to almost 500 it rips, even with 22’s. I can break the 22’s loose without an issue at a standstill. When I put it in 4wd it just squats and takes off like a rocket. Love the truck.
I've owned both. Had a 2014 ltz z71 that I got before the 6.2 was available in that model. Was happy with it. Did a cat back exhaust and cai with tuner. Was a fun truck. I finally traded it in. Picked up a 2021 Sierra Denali with the 6.2. Drove straight from the lot to the exhaust shop. Had it for about 6 months and it's a huge difference in power. Cai coming soon and waiting for a good tuner. I'm sure it'll really come to life then. Go with the 6.2 if it's in the budget!
1st.....War Eagle! Second, I own both, both loaded Denali crew cabs. The 6.2 is not only way more fun, but tows and hauls better, and if you keep your foot out of it actually gets slightly better mileage on the same trip with all other things being equal.
The 5.3 Is pretty good but with a few Upgrades Some headers, Cold air system, Custom exhaust, And the biggest upgrade I did was 4.10 Gears It has a 6" left and 35" MT With all that power now Believe it or not I can turn those 35s Thanks for the video.
I have 2018 6.2 with 200 000 miles on it now. Premium fuel for every mile. It is a pilot truck we run big loads only 24 feet or wider is our specialty it runs pedal to the floor no mercy from one wide spot to the next, all day. I smile just like you every time I floor it. My Dad refuses to run Premium in his he has had some sensor issues. But he says he will buy the 6.2 again. He bought a new 2018 with a 5.3 I bought the 6.2 he drove mine when his was about 2 months old got in his went to town and came home with a 6.2!!!!
Ive had both, love the 6.2 and I usually run 89-91 in it (depending on gas prices🤐) but with my experience I do find that my 6.2 is actually better on gas vs my 5.3 I had previously
@@RobertoHernandez-cd9bs If you run 91 the 6.2 gets better millage than if you run 87. I'm not sure if that would translate to beating a 5.3 on 87, but if you're driving conservative it might. My 6.2 gets about 1.5mpg more on 91 and it is noticably more sluggish on 87.
E85 only makes a difference if you have a tune and even then its not the biggest difference e85 is better for boost turbos and superchargers, so settle down beast boy if anything you gain 5 hp
Honestly, my 2023 silverado with the 2.7 turbo, 310 hp and 430 lb.-ft. of torque. Payload 2,020 lbs trailering 9,000 lbs, is good for me. It has a hell of a hole shot too. Glad I got it.
The 6.2 with the max tow 3.73 rear end is just flat out amazing. If you leave the traction control on you literally will still get great times. Well, at least if the road is dry. The 5.3 is a strong motor as well but it just doesent compare. 100 hp will do that to you. Throw in an exhaust and a CAI and not only will you tow like a beast you will surprise the hell out of guys who think their civics and subarus are fast. The 6.6 in the 2500 is stout "running that now" But with the extra weight of the 2500 its nowhere near as fast as the 6.2 in a 1500. Bottom line Spend the money, get the 6.2. More power!!!! argh argh argh :D
Ya problem with gm tuning gains are limited, Ford's 5.0 you can tune gain 100hp from tune, intake and cai. Ecoboost huge gain but of coarse boosted unfair comparison
I’m still salty I didn’t get my hands on a 6.2 but I blame China for Covid. Literally every dealership in my area all had 5.3’s only. It sucks but, I still love my RST.
I just got back from a 2200 mile drive from Portland to Los Angeles and back with my 2021 6.2 gmc at4 and it was a blast. It was a dream to pass all The Prius’s clogging up the passing lane. I also ended up with my best gas mileage at 25.9 miles to the gallon.
Late to the comments on this one but looking at a 2021 AT4 with the 6.2. You really get almost 26 mpg with yours? 91 or 93 octane been a stinger at the pump?
The 6.2 also gets better mileage because it’s literally never really working in normal driving conditions. I love the 5.3 as an absolute workhorse, ultra reliable motor, but the 6.2 is worth every cent on the sticker.
I have a ‘19 5.3 LTZ with the max tow Pkg. So it comes with a 3:42 posi . Runs good, gets good fuel economy and I don’t need to run premium… My ‘19 C7 Grand sport feeds my need for speed….
I had a bunch of these….. 1982 3/4 ton 2WD Suburban with a 350 (hot rodded up a little bit) 1994 3/4 ton 4WD Suburban with a 350 (stock as a rock) 1999 3/4 ton 4WD Suburban with a 454 (7.4L) (hot rodded up a bit) 9” of lift with 36” tires 2002 1/2 ton 4WD Tahoe with a 5.3L (completely stock) 2006 1/2 ton AWD Yukon Denali XL with a 6.0L (stock) 2013 1/2 ton AWD Yukon Denali XL with a 6.2L (stock) Current vehicle. It tows great and would absolutely kick butt on any of the others that I have owned. It’s really a great vehicle. I’m all about the power!!!!!!
Guys i love these trucks with the 5.3, not degrading them at all. Just a fun comparison video between the two engines!
i got a 19 trailboss with a 5.3 because surprisingly it tows more and I needed that

DAMN I GOT THE WRONG ENGINE JUST NOW
In a PERFECT world I would like to have gotten the 6.2 but, I'm honestly happy with my 5.3...
and you're right the10 spd
makes a big difference.
my 16 had the 8sps.
My 09 has a 4 speed, literally my least favorite thing about my truck lol...
I agree! I was at a Toyota dealership and found my 2017 GMC Sierra SLT 5.3L as a trade in there. Was the only GMC on the lot and I love it. If I was able to choose which engine came in it, I'd have taken the 6.2 but the 5.3 is great as well. Maybe I'll procharge it at some point and make up that extra power lol. But mine came with the 8 speed which is great, has a sunroof, heat/cooled seats, etc. Practically every upgrade you can think of. Big upgrade from the things I've owned before haha. And I'm only 22 so there's plenty of time to upgrade later.
But less electeical@@TGravy-wp4rc
I wished Chevy would start offering the trail boss with 6.2 supercharged from the factory with about 750 horsepower.
It's cheaper to add a turbo or supercharger yourself. I have a modest turbo and some tuning on mine, and pull 12 sec quarter mile times at just over 120mph.
@@ISeeYouToo-Ido Almost always better to have it from the factory.
@Boguardis Maybe. I had a 1 of 1 2010 6.2L Z71 shipped to a North AL dealership, where they installed an Edelbrock supercharger at the factory, tuned literally everything to what they called 'perfection,' making right at 840whp, and it lasted only 47K miles. And, it honestly had an easy life. We put in a brand new motor, and I installed a Paxton, and a canned tune, and she has 288K miles on her, and still jerks this camper and bassboat around like they are empty balloons. Haha. Almost 300K miles, and still rocking right at 750hp. Not too bad.
@Boguardis Oh, and for clarification, my 12 sec truck is a 2021 6.2L on 35s. 😅. Just once, I'd like to put on some slicks at the track, and see what it can really do, but my conscience says something will break. Haha.!
I love the smirk! You’re the right guy for the job. I have the 3 0 diesel. The only reason I didn’t get the 6.2 is the high test thing.
It is OK to run on 87 per the manual.
These trucks are fast for being as big and heavy as they are wow I'm impressed
One of the BEST side-by-side comparisons I've watched on RUclips, bar none! You've given me some great info to consider as I decide on the engine for my next Z71 Tahoe/Suburban.
GREAT video...nicely done. My last two GM trucks had the 5.3L. My new truck (2021 GMC Sierra AT4) has the 6.2L. BIG difference. It also has a CAI, Borla muffler (flapper delete), Pulsar LT, and stock wheels (with one size taller Bridgestone Revo 3 A/T tires). No added weight with the tires. I call my current AT4 "a Corvette with four wheel drive". I didn't buy it for fuel mileage, or being in the slow lane. 91 octane is good. 93 octane is hard to find here in Oklahoma...but, it is def better. Thanks for doing an excellent real world video comparo. The 6.2L (to me) is the way to go and brings a smile to my face every time I wanna drive like Dale Earnhardt Sr.
Which Borla muffler do you have? I'm thinking straight pipe in the 22 Trail Boss 6.2 I just got! Keep the resonators on of course for drone. I'm down by Texoma and can't find 93 fuel anywhere.
@@yustinaaron - Congrats on your new truck! I have the Borla ATAK muffler (and flapper valve removed). It is "alright" with some highway drone. Prob better/cheaper to do a straight pipe/muffler delete...but, to each their own. As for finding 93 in Oklahoma...good luck! Texas, Arkansas, Missouri, no problem. I find the "winter blend" Shell 91-octane pretty decent. I have run 94-octane (VP racing fuel here in Oklahoma City) -- def fun. But $5+ a gallon.
@@ChrisDIYerOklahoma I see from your previous comment that you have the Pulsar. Does it void the warranty? Do you mess with the throttle setting?
@@yustinaaron -- Best $500 I ever spent. No, it doesn't void the warranty (Pulsar says to remove it before taking a truck into a dealer for warranty work). Also, leaves no bread crumb trail. Yes, I have mine set on "3" and it is fun!
@@ChrisDIYerOklahoma thanks for the info!
we need more of these again!! clearly people loved it man
I’ve had two 5.3 trucks and now a 6.2..huge difference. But still like the 5.3...it’s a solid engine.
How much more different¿ and how does it do in and off road differences?
When they're racing each other the 5.3 is literally a second right behind the 6.2...Unless you're just racing everyday the 6.2 is not needed..
@@blast4me754 the 6.2 is literally over a second faster in the quarter mile and 0-60 which is huge in performance.
6.3 seconds vs 5.1 and 15.2 vs 14.1. The first day I picked up my Escalade, me and my gf were driving in separate vehicles and she was in her 2018 5.3 sierra ..she was pissed because I kept walking away from her on the highway lol…no, you don’t need the extra power, but it’s plenty noticeable.
that baby seat was weighing down that 5.3! Good video man! i have owned both and i love the 6.2 for towing!!
I agree the 10 speed is the biggest help to the 5.3L. I think it still has more in it with a gear change

Smoked the last 10 speed 5.3 I raced. Yes they are an improvement.
Dude! This is such a great video! I've debated myself on the merits of the 6.2 versus the 5.3 . Wow, this is very informative. 6 2 is the way to go if you want performance, and, if you can afford it, is the better choice. It performs better, it sounds better, and has a much more visceral experience while going up through the gears. And a 13.86 is an awesome quarter mile time for a truck! Very competitive. Kudos to you for this video. And kudos to Chevrolet for still offering a large displacement V8. And for raising the top speed governor on these trucks to 112 mph on 2021's and after! Yeow!
I have a 5.3 2018 sierra with the 8 speed. How much did you pay for the engine swap? Including the engine what was the total price?
This 5.3 is reliable but it's just not as fast as I want it to be lol.
112mph*...that's where mine used to shut off but I've had that taken care of.
6.2 needs Premium Fuel. But worth it.......
1 million dollars
Until the push rods go on it. That seems to be their issue.
I love this dude, drag racing with the car seat in the back. Lmao. Love the video.
My 5.3 Silverado dosnt stand a Chace against my 6.2 Yukon Denali, the difference is night and day. Once again great video man!
Same here my wife has the yukon denali and here I am with the 5.3 trail boss lol
In my 5.3 I definitely get a better and faster launch from just stepping on it rather than holding the brake.
I noticed that as well
This is the case in my 5.0L F150 as well. If you try to brake torque it, it actually feels like it bogs or doesn't give power for a split second when you mash it.
You have to rev it to a certain rpm. Hold ur traction control till it turns off advanced track
@@evictioncarpentry2628 You own a Ford ? 😂😂😂😂😂 I feel sorry for you.😅
Agreed, these oem converters like to be flashed off the launch rather than stalled.
I have a 19 6.2 high country with 22inch rims. I had a 17 5.3 and I can feel the difference. Purchased the truck used but the drivetrain (motor, camshaft) had been replaced. Engines brand new lol I’m basically breaking it in right now. I’m happy with the vehicle
Totally agree. The 5.3 is a good solid engine (but do frequent oil changes, don't go below 30% oil life). That being said, I got my 2019 AT4 with the 6.2 because... Just because. It's badass!
30%? Damn
@@alexs.5675 Yeah. The issue is the way the oil flows over the top of the heads from the rear of the engine. Eventually the valves start sticking until eventually you have a valve failure. PITA to replace. Not devastating to the engine (you will lose that cylinder), but really tough to get to.
I have at4 6.2 and i always have to change before the time , it gets low too fast without leaking
YUP, especially the 6.2. Lifter issues, valves and rods break. It requires very careful maintenance
Yeah, the lifter issues were bad for MY 21-22. If you have one of those, consider contacting your dealership before the engine goes kaboom. Before or after should be fine. They changed their lifter design, and then went back I understand.
I might be the only one saying this but I MUCH prefer the look of your truck with the lightweight wheels and tires. It probably performs better in every conceivable scenario with the smaller tires as well.
Great review, I have an ‘18 5.3 6 speed that’s just my luxury daily driver. But my son’s’19 5.3 8 speed is a world different. Smoother, faster, quicker & 25 mpg driving across country!
Count your blessings you have the 6 speed. GM has a huge issue with 8 speed, very unreliable. Pay attention to shifting in your 6 speed. These transmissions have weak torque converters. They slowly come apart and metal filings will get into the solenoids causing occasional hard shift when slowing down. Once you notice that, immediately change out torque converter. You have roughly 6 months till transmission fails from that point if you don’t change out the converter. GM rebuilds are around $5000. 8 speed is even worst. More prone to failures.
great video, thanks for sharing. 1 second faster in the 1/8th mile is a big difference. I live in Wyoming and the elevation here is 7,000 feet above sea level. I've been wanting a Chevy with a 6.2 LS/LT engine for a while because of the power difference between the 5.3 and the 6.2 and this illustrates that perfectly.
Can't tell you how much I appreciate these videos. I ended up buying a 5.3 and while waiting for it to come in I saw this video. Ended up breaking the contract and getting a 6.2l and man I'm glad I did. These videos saved me
A year or so in now with the new 6.2 ... hows it been keeping it gassed up with 91+ octane? Still feel you did right getting it over the 5.3?
Love my 6.2 it’s daily driver pulling a trailer everyday all day for work ! Awesome
Awesome video, I got the 5.3L for a steal and added a Magnuson TVS-1900 and pretty much took care of power difference between them. The 6.2s are harder to come across but the price difference really isn’t bad between them if you find one.
What’s your gas mileage after putting in the super charger?
@@Sabertooth_54 City 18-20 with highway 23-28mpg That’s the reason I chose the Mag was because the gas mileage I was told wasn’t really going to change. At cruise there’s like a 1/3hp parasitic loss because of cruising bypass valve. I do need a better Trq converter however in the future lol
I literally had to gap my piston rings😩🤒... Found out the hard way 🤦🏾♂️, blow by... I think I'm saying that correct 😬🤷🏾♂️
What other considerations did you need to take care of after installing the supercharger? Transmission, rear end, suspension?
@@mikerdz75051 The other considerations taken were the driveshaft (OEM is thin with a 115mph critical speed failure) and the transmission is next on the list. Unfortunately GM made the torque converters and transmission pumps very poorly in general so replacing is guaranteed. These components are cheap for GM and will fail as mine has begun to do. I do wish I’d have changed the torque converter earlier on but it’s a gamble if the trans pump fails.
I had a 16 silverado 5.3, 6 speed i loved it. I tuned it with black bear performance, and I installed long tube headers. i also made it E85, CAI, and deleted the auto shut off. It's such a sweet truck it was night and day after those mods
6.2 tows a lot better and gets better milage than the 5.3 while towing. Definitely less stressed and lower rpm while towing.
Just bought the 6.2 LTZ. Loving it power is insane
6.2 is great, I used to have one. I have a 5.3 now, and I’ve had several, and for me it’s plenty. Runs great, enough power for my needs. I don’t really lust for the 6.2. Call me crazy. Maybe I’m just getting old and boring.
You’re getting old !
I have a 5.3 on a Tahoe but now I want to do a single cab short bed Silverado with a 6.2
Nah you're just getting smarter, better mpg with the same capabilities. 5.3 is no slouch but the 6.2 requiring premium 93 and worse mpg is a no go
My 2018 Tahoe has a 5.3. I believe 3.73 rear end. It has a 6” suspension with 33x12.50 ….. maybe its just me lol but i feel like the truck moves. Im very happy with it. No problems catching up with traffic, merging on to highways etc
I have been very fortunate with GM! My 04 z71 with the 5.3 is still running like a top. Original everything except for plugs, wires and coil packs and runs like a scalded dog. Also very fortunate with my 15’ Denali with the 5.3. I have 6 inches of lift w/ 35’s and 26’s and can absolutely roast them down when I turn the stabilitrack off and it’s stock besides putting .410 gears front and rear. I also love the 6.2 but the 5.3 to me is one of the most well built engines/blocks ever produced
Except for arm/dod , fuel injectors ,
After vortec ls the engines became low mileage
@ I agree with you for sure. The 14-18 5.3’s have lifter issues bc of that flex fuel 4 cylinder bs and the transmissions are GARBAGE!! Two easy fixes tho. AFM/DFM disabler and the updated trans temp sensor. Factory trans temp sensor kicks on at 194°…that’s just shy of boiling and cooks the trans fluid and wears it out prematurely. New one kicks on at 154°. Factory trans fluid in the 14-18’s is also trash!!
Great Video! I think the reason they raised the price so much for 2022 on the 6.2 is because they need money to pay for all the 2021 engines that had to be rebuilt!!!
Exactly and I had one of those 2021 engines. Blown lifters.
With the +/-1mpg difference it was a no brainer for me. 2020 TB with the 6.2l is quick. Most everybody who gets in is shocked how fast it is... Love it!

Can we just appreciate the Chevy Silverado line for a moment. Great video
I'll pretty much say everybody with the 5.3 would rather have the 6.2 in a perfect world. If I told you the 5.3 is just fine (which it is) doesn't mean they wouldn't rather have the 6.2. I do have the 5.3 and it is just fine but..... would rather have the 6.2. My brothers ecoboost is amazing as well but i like v8 push rods . But I am old
A cam headers and a tune a 5.3 will not be beat by a stock 6.2😉
Right, and the same goes for the guys with the 6.2...im sure they would rather have a 6.2 super charged ming 800 hp lol.
I drove both and the 6.2 needing premium and being terrible on fuel i opted out. Getting 10mpg with the 5.3 until it got some miles on it was bad enough. Personal preference but if you cant pass someone in a 5.3 with a 10spd the 6.2 might not either.

Great comparison video. Straight to the chase and informative. Would LOVE to see a similar idea but comparing your 6.2 to a newer 5.0 f150 or 5.7 ram 1500
5.7 would get slaughtered, its closer to a 5.3 in terms of performance than it is the 5.0/6.2. The 5.0 vs 6.2 honestly seems to depend on the driver they are really close.

@@h1tman-640 not really. Closer than you think.

That ghost white 6.2 is glorious!
I had new 5.3L Silverados in 2008, 2012, and 2016. I bought a new 2019 with a 6.2L. The 6.2L get better mileage than the 3 previous trucks. The required 93 octane for the 6.2 costs 20% more, but it gets about 10% better MPG than the 5.3's. Probably due to the 10 speed transmission.
Having 4 more gears definitely helps lol
I put the L92/Vortec 6200 in my 05 Yukon XL SLT 2 wheel drive and i love it!!
well said. I love my 21 tb with the 5.3 and ten speed. Tows great. exhaust, intake and pedal commander do help ;)
The 6.2 is almost as fast as my F150 3.5 HyBrid Powerboost. If they could fix the interior, I would consider switching. Fun video, keep them coming.
I totally agree the interior is not for me
I still can’t see the value in the 6.2. At the end of the day it’s still a truck, not a sports car. You’ll pay more for the engine option and here in eastern PA you’ll pay .80$ more a gallon. It’s not apples to apples. If they both ran in the same fuel, then I’d talk. With the 5.3 truck it weighs just a hair over 5k pounds and has 355hp, that’s not weak like most of you guys are saying.
It ain't weak but it sure is the weakest in the truck segment, ford makes 400HP with a 5 liter and Chevy can't hardly make 400HP with a tuned up 5.3
@@chrishansen7004 the ford 5.0 makes 395 horsepower stock, and the 5.3 makes 355, the difference is negligible. I've seen many stock chevy 5.3s keep up fairly well with ford 5.0s and beat Ram 5.7s easily. And the 5.0 requires 93 octane like the 6.2, but will still get mopped by a 6.2, meanwhile the 5.3 you can run on e85.
Drive ability for me. I had a 2009 5.3 then a 2012 Denali with the old 6.2 and I had a 15 5.3 and now a 2020 with a 6.2. I prefer the 6.2 just for the feel. I don’t have to be racing around which I don’t it just feels better. Takes less throttle and doesn’t feel as pokey. Also when I go to merge onto the interstate or overtake a slow moving vehicle it feels better to have more power. I agree though technically the 5.3 isn’t really slow it’s actually putting up numbers “sports” cars did years ago.
@@ThenotMrNiceGuy0109 you’ve seen plenty of stock 5.3s keep up with stock 5.0s? Maybe the gen 1s. Gen 3 5.0s mop up 5.3s all day stock for stock.
6.2 isn't about value. It's about power
I had a 2017 Silverado crew cab 4x4 LTZ 6spd auto with the 5.3.
It was good. But it always felt like it needed more. I put an cold air intake on, tune & a exhaust system. Better, but still seemed a little lacking.... Now I have another 2017 Silverado crew cab 4x4 LTZ with the 8spd auto & the 6.2l. Much much better overall. It is noticeably faster but surprisingly it gets slightly better fuel economy than the 5.3. I'm guessing the 8 vs 6spd has to help, but it is just a way better experience now. Imo it is a very worthwhile option if your in the market.
My 2019 5.3 is about all the tires can handle and personally I bought it for comfortable ROAD TRIPS
I appreciate your vids. I got the pulsar because of YOUR vid. I have the pulsar intake also because of YOUR vids. I appreciate your knowledge and experience, thank you. I have the 6.2 custom 2022 trail boss...I LOVE IT
Max trailer tow package on the 5.3 changes the rear axle ratio..
Think it makes a substantial difference having the 3.42s
That lt1 putting in work! Man I miss my 2019 camaro ss
Both are great engines and have plenty of aftermarket support
Don’t know about that. I brought a brand new 2021 5.3 RST and within the first year the engine lifters failed. Had them replaced but still did not feel good about the truck. Traded it in for a 5.7 tundra. Love the look and design and comfort of the Chevy Silverado but the reliability sucks.
I have the 2022 refreshed Z71 Trail boss LT midnight edition with a basically 7 foot bed, and I love it! My truck runs great for personal use, for work, and off-road. If I needed more power, I might get the 6.2, but I can also do some upgrades that will give me that power.
I know this isn’t what the video is about… but the black trailboss looks absolutely sick with the 24s!
That smile when you launched the 6.2 said it all

Definitely not the same setup as your 5.3, but just giving props to what the 5.3 is capable of while still keeping some fuel economy.

Shit for the money you put into the 5.3 you could’ve had a 6.2
I have a '19 Sierra Denali 6.2 with CAI, exhaust, 22" wheels, 275/50 tires. I got 22.5 mpg (trip average) on an 85 mile 65-70 mph highway trip climbing 1600 ft elevation (~4700 ft-> ~6300ft), passing a few people, full bed, full tank, with wife and 3 kids, and then 28 mpg (trip average) on the way back all on 91 octane. I also pulled an 8,000 lb travel trailer 20 miles (flat no change in elevation) and ended with 16 mpg (trip average) on 87 octane (would have used 91 if I knew I was going to tow). This morning on my way to church 6.5 miles away (flat) my trip average was 24.1 mpg and 25.1 mpg on the way back and there's 7 stop lights, 2 stop signs, and a roundabout with 35 - 50mph speed limits (87 octane). So glad I got the 6.2. I wrestled with getting a truck for years, for fuel economy and practicality reasons, kept trying to cram everything into our SUV that I could get 25 mpg - 30mpg. I have zero regrets now.
Ended up with the 5.3 and it is a good motor but I still remember the 6.2 that I test drove. If I could have found the configuration I needed with the 6.2 that’s what I would rather have had. Though I am glad I don’t have to run 93. Great vid!
I ended up with the 5.3 also during this shortage I feel like the only 6.2s I saw were high countries
I have had the 6.2 in every truck I have owned since it was offered, and I never run 93. No issues in any of them, my wife's Denali will ping a touch in high heat but she does not drive like me, so have not worried about it as all oil samples are in-line.

I try to avoid that happening, but when it is unavoidable, I will run the mix of high/low grades in most of south TX, which results in 91 advertised, but I think it is closer to 90. The oil reports for both current 6.2's wear metals are as expected for the mileage. I know both are likely down on power (some timing pulled), but they have so much more torque than the 5.3; even using 87, there is really no comparison. My truck does not show the same higher heat load ping as the Denali. I am guessing the weight of the SUV is playing a factor there.
Here in west Texas you don't find 93 octane only 91
I've never put 91 in my 6.2. Runs great. 24000 miles on a 2021. From full weight towing to just normal driving. Got mechanic friends that work on them Everyday and swear the 91 isn't needed. I'm a believer. Love my 6.2. It does haul@$$
It just pulls a lot of timing so youre not getting near the power available. It would knock bad otherwise. I wouldnt tow with it a lot like that. Science
I'm currently on my 4th 6.2 now, almost always run 87, maybe a tank of 91 every once in a blue moon if I just got paid or something but I've never really noticed a difference. The yukon and sierras I've had all made it well over 100k without any pings or other issues besides the 8 speed that shit the bed around 170k but that's got nothing to do with octane. My dad was a chevy mechanic for decades and always told me it was a scam unless you've got a vehicle that knocks without it. My '72 c20 on the other hand...
@@carterantebi8776 Yeah it will run on 87. Just very decreased power and the mileage to go with it. Its about science. Very high compression with low octane means a lot of pulled timing which decreases power. Couple that with towing, pulled timing, low rpms its just not what it was designed for. Direct injection only helps so much
Thanks for this video! I traded my custom 19 trail boss 5.3 for a 21 custom tb 6.2 10 speed. (Actually got the new one for 44,500) and traded the 19 for 43,500 lol)
I clocked my 6.2 at 5.08 a month into owning it. Much lighter due to less options compared to the LT.
Love these trucks.
My 01 2500hd is about 6.8 ish seconds 4 speed but I get like 8 mpg city 12 highway
6.0 vortec only 1500 miles on the engine 40k on everything else
@@treyworth8842 quick trucks. My father had an 05 2500 with a 8.1 496ci and immediately put a whipple on it. Truck was nasty
@@Buyonegettwo exactly the 8.1 is an amazing engine I'm actually interested in getting a new truck as I want a crew cab probably the new small duramax
Nice! Excellent job on the comparison. 6.2 is a beast.
You did a great job comparing the two..not hating on your truck but it looks new again with the factory wheels on it..love the bull dog look with factory wheels and little bigger tires all within the confines of the wheel wells..I love wide wheels and big tires but late model trucks have wider tracks than older trucks and to me they look right just adding bigger tires and leveling them, they just look newer longer
I can't lie from MY perception you drove your truck more aggressive than the other plus there are mods done even exhaust makes a difference in performance but all in all great video‼️
I love my 6.2 I got my fully loaded 2018 SLT z71 for 46K new. I test drove a 5.3 back in 2018 and it couldn't find its way out of a wet paper bag.
I love the way these V8 trucks sound especially the Hemi Rams!
Owned the 6.2 and it was a great motor. But I don't miss having to put 91 octain in and the 5.3 consistently get 2 mpg better. To be fair the right foot could have been a little heavier with the 6.2 😂
I saw the same thing but closer to 4 mpg
On longer trips I have found the 6.2 gets awesome mpg. On one 100 mile trip with a tail wind I hit 29mpg avg in my Denali. avg I get about 24 if I'm gentle.
Put 86 in my 6.2L honestly don't notice a difference in mpg or horsepower.
@@foxwithshades7080 I just don't like doing so being that it's a direct injection engine and it also has to compensate timing and other things due to the lower octane fuel.
Edit: what do you get for mpg?
I was a BIG 5.3 Fan, However bought a sierra with a 3.0 Duramax, and I love it. Yes it has issues, Long crank and 150K oil pump belt. But I've had ZERO issues with it and now have over 20K on it. About to change fuel filter with next oil change.
The worst thing about the 6.2 is the recommended 93 octane. Mine definitely prefers 93. Lose on acceleration and some fuel knock with 87. Other than that they are great.
My first thought when he announced comparing the two. For the next three years at a minimum the pain at the pump will be real
we run our 17 with 87 all the time, never heard any knock
That’s dangerous to not put 93 in
@@Yoursistersazz we dont even have 93 here
@@deek431 same here and never had a problem
I recently test drove identical Trail Boss's, one in 5.3 and 6.2. after putting my foot too it, I opted for the 6.2. Later I learned that the sales dude set the 5.3 in normal throttle mode and the 6.2 in sport. Regardless, the 6.2 is a monster after 10 years of driving me 4.7 Tundra. As far are fuel economy goes, I commute around 45 miles each way on hilly 2-lanes running 87 octane. The 50-mile average MPG is just shy of 17. I ran a couple of tanks of 91 octane as we don't have 93 in my area. I didn't see a noticable difference. At least not enough to justify the extra $ at the pump.
Be careful running 87 in a 6.2, I did 87 and 93 about 50/50, had a bad engine misfire after putting 87 in one day and was told that can happen running 87. The CEL stayed on until I ran the tank empty, put in 93 and it almost immediately went away.
Don’t put 87 dude wtf wrong with u in a 6.2 u need 93 fuel in the 6.2 sooner or later you’ll engine will be knocking from what I heard
@@rook3364 “from what I heard”
Then you don’t actually have any experience. Got it. The manual states it can run on 87. Straight from GM. Typically I’d put 93, but on occasion I’d put 87 to compare mpg and performance. In my SS I never put in anything below 93, but you’re not driving a 6.2 truck like an SS camaro. Especially on the highway
Great video. My 21 6.2 AT4 has way more power than my 18 Silverado 5.3. Once again great job
I have the 6.2 in a Black Widow Chevy 1500. With the upgrades in HP to almost 500 it rips, even with 22’s. I can break the 22’s loose without an issue at a standstill. When I put it in 4wd it just squats and takes off like a rocket. Love the truck.
I had a black on black GMC Denali with a 6” lift and a 6.2. I now have a Chevy Silverado Black Widow with a 6” lift and 5.3. I really miss the 6.2. ☹️
I've owned both. Had a 2014 ltz z71 that I got before the 6.2 was available in that model. Was happy with it. Did a cat back exhaust and cai with tuner. Was a fun truck. I finally traded it in. Picked up a 2021 Sierra Denali with the 6.2. Drove straight from the lot to the exhaust shop. Had it for about 6 months and it's a huge difference in power. Cai coming soon and waiting for a good tuner. I'm sure it'll really come to life then. Go with the 6.2 if it's in the budget!
1st.....War Eagle! Second, I own both, both loaded Denali crew cabs. The 6.2 is not only way more fun, but tows and hauls better, and if you keep your foot out of it actually gets slightly better mileage on the same trip with all other things being equal.
I like how you used the same wheel tire combo for the testing
The 5.3 Is pretty good but with a few Upgrades Some headers, Cold air system, Custom exhaust, And the biggest upgrade I did was 4.10 Gears It has a 6" left and 35" MT With all that power now Believe it or not I can turn those 35s Thanks for the video.
What it cost to do the regearing to 410 cost you and who does it
I have the 6.2
Do the same to the 6.2 and it’s the same outcome, 6.2 sits on top.
Or save money and get a 6.2. Same outcome.
Night and day. Over a second in the 1/4 mile is enormous. Great video!!!
I love tests like this.
looking at the black trail boss with the 24s looks good shoulda bought a black one
Black has a tendency to show more dirt on the body.
I have a 5.3 6 speed 3:42 rear and have it running nice right up to when it fell on its face at 98 mph
The 6-2 definitely sounds better. And with those bigger wheels and tires you have a lot more rotational torque to overcome.
I have 2018 6.2 with 200 000 miles on it now. Premium fuel for every mile. It is a pilot truck we run big loads only 24 feet or wider is our specialty it runs pedal to the floor no mercy from one wide spot to the next, all day. I smile just like you every time I floor it. My Dad refuses to run Premium in his he has had some sensor issues. But he says he will buy the 6.2 again. He bought a new 2018 with a 5.3 I bought the 6.2 he drove mine when his was about 2 months old got in his went to town and came home with a 6.2!!!!
Ive had both, love the 6.2 and I usually run 89-91 in it (depending on gas prices🤐) but with my experience I do find that my 6.2 is actually better on gas vs my 5.3 I had previously
How's that possible? I just bought a 6.2 Boss
Get great mpg for 6.2….21.5 - 24.5 depends on wind,temp etc but I’m very happy
My 17 Suburban with 5.3 got much better gas mileage than my 21 high country 6.2 around town. Highway mileage it is much closer though
@@RobertoHernandez-cd9bs If you run 91 the 6.2 gets better millage than if you run 87. I'm not sure if that would translate to beating a 5.3 on 87, but if you're driving conservative it might. My 6.2 gets about 1.5mpg more on 91 and it is noticably more sluggish on 87.
Two days ago bought the 2022 Silverado RST 6.2L verses the 5.3L. I drove it about 200 miles home, nice smooth ride. Happy with the 6.2
Love my 2011 6.2. It’s a blast to drive daily on 93 fuel. But goes into total beast mode when I run E85 occasionally, since it’s flex fuel 😉
E85 only makes a difference if you have a tune and even then its not the biggest difference e85 is better for boost turbos and superchargers, so settle down beast boy if anything you gain 5 hp
@@rafaelmendez4477😂
"Beast Boy"🤣🤣
Honestly, my 2023 silverado with the 2.7 turbo, 310 hp and 430 lb.-ft. of torque. Payload 2,020 lbs trailering 9,000 lbs, is good for me. It has a hell of a hole shot too. Glad I got it.
How about doing the same runs on the 6.2 with the 24” and see how that affect the numbers you already have. I really want to see the difference.
I agree. I want to see what the big wheels cost for performance
I have an 06 SS 6.0 2wd and when I take traction control off she’s a blast! I can only imagine these 6.2s. Not letting go of my baby though.
The 6.2 with the max tow 3.73 rear end is just flat out amazing. If you leave the traction control on you literally will still get great times. Well, at least if the road is dry. The 5.3 is a strong motor as well but it just doesent compare. 100 hp will do that to you. Throw in an exhaust and a CAI and not only will you tow like a beast you will surprise the hell out of guys who think their civics and subarus are fast.
The 6.6 in the 2500 is stout "running that now" But with the extra weight of the 2500 its nowhere near as fast as the 6.2 in a 1500.
Bottom line Spend the money, get the 6.2. More power!!!! argh argh argh :D
Ya problem with gm tuning gains are limited, Ford's 5.0 you can tune gain 100hp from tune, intake and cai. Ecoboost huge gain but of coarse boosted unfair comparison
You can't get the 6.2 with 3.73 gears for a few years now
I have the Silverado with the Intruder package 6.2L and I love it.
I’m still salty I didn’t get my hands on a 6.2 but I blame China for Covid. Literally every dealership in my area all had 5.3’s only. It sucks but, I still love my RST.
5.3 still a great truck!
I'd waited
Great video bud I don't own either but I was curious keep up the great work
The 6.2 laughs when you fill up the gas tank!!!! Gas prices suck under Joe Biden

I just got back from a 2200 mile drive from Portland to Los Angeles and back with my 2021 6.2 gmc at4 and it was a blast. It was a dream to pass all The Prius’s clogging up the passing lane. I also ended up with my best gas mileage at 25.9 miles to the gallon.
Late to the comments on this one but looking at a 2021 AT4 with the 6.2. You really get almost 26 mpg with yours? 91 or 93 octane been a stinger at the pump?
The 6.2 also gets better mileage because it’s literally never really working in normal driving conditions.
I love the 5.3 as an absolute workhorse, ultra reliable motor, but the 6.2 is worth every cent on the sticker.
I have a ‘19 5.3 LTZ with the max tow Pkg. So it comes with a 3:42 posi . Runs good, gets good fuel economy and I don’t need to run premium… My ‘19 C7 Grand sport feeds my need for speed….
The small rear ends really hold them back as well. Both will need transmissions before 100k also.
A friend of mine has a 19 Sierra AT4 his trans shit the bed at 10,000 miles
@@charliegugino8047 I had a 2012 and a 16 that both had trans replaced before 30k

By the way you’ve got a really great video.
I really want the TB + 6.2 but the tiny fuel tank is a deal breaker.
Thank you I'm old and 5.3 is good with me great review
