🔥Great Job Guys, Love the Entertainment🙏
It would be even more entertaining to see them all climb in and parachute out of those trucks.
The prices of these trucks and most new vehicles are absolutely insane!
I see this comment all the time… guess what ppl reckless politicians have driven the value of our currency to shit and prices across the board aren’t coming down. Make more $ to keep up or get left behind. That or get out the pitch forks
And yet they’re selling as fast as they hit the lots.
@@khakiswagno longer true. The trucks I’ve been targeted with have been sitting on lots for a while now. I had to pay adm on a raptor during the pandemic and now there are ones sitting on lots at msrp or slight discounts. The at4x diesel I looked 3 months ago is still sitting on a dealer lot with about a 10k discount
@@khakiswag sales are way down. Big discounts and sales incentives will be coming very soon.
@@herbwheeler4470Nah, they are just cutting production.
Over the last 20 years I've leveled more trucks and Jeeps than I can remember and 33 to 35" tires usually go on immediately afterward. The MPG loss on all of them has been 1.5 to 2.0 each time. Doesn't sound like much, but at $3.50 a gallon it does add up quickly over time.
It does. I've done the calculation before and in 300,000 miles you can spend an extra $21,000 for a 5mpg difference. I tried telling that to the Tundra owners getting 13 mpg that they weren't saving any costs in the end.
Usually you're going from a street focused tire to a dirt focused tire at the same time.
One factor to consider is in the winter they blend diesel fuel to avoid gelling. I find my mpg is about 3 to 4 mpg less on my 3.0 GMC with this current winter blend. It would be interesting to see this same loop with the same truck when they switch back to summer blend. I average 23 mpg in winter and 26 to 27 in summer. (GMC AT4 I'm south of you guys in Pueblo area) You can check with distributor to see when they switch between winter and summer blend. Agree with most subscribers...always great content from you guys.
I wonder if the whole country gets the winter blend or just areas that stay below freezing the majority of winter.
It's my understanding the distributors switch to winter blend based on area weather conditions...I know when living in Alaska they would blend 50/50 #1 and #2 diesel about the end of October. Got terrible mileage. Your though is correct, I would bet that Colorado they do mix it. I can remember one year (90's) we had a cold snap in Alaska before winter fuel deliveries and there must have been 10 to 15 Dodge Cummins gelled up on the side of the road.@@JonBecker81
lol glad you brought this up, my 06 runner gets terrible mpg in the winter to and from work, last time i calculated it was about 13-14mpg, normally get close to 17. No highways on my way to work lol. my best mpg in the summer highway was about 22 driving like a grandmom.
@@JakesPlaying06 Runner like 4Runner? Is it a diesel?
The cold ambient air (IAT or intake air temperature) plays more of a role in your winter fuel economy that winter diesel ever would. Cold weather and worse fuel economy go hand in hand for both gas and diesel engines. Your engine requires more fuel to maintain operating temperature regardless of which of those it is. A winter front would likely restore some of the lost fuel economy you are experiencing. TFL if you are reading this maybe you could try this test again after blocking off the radiator in both trucks leaving just a small amount open for air to pass or block the front grille completely. If the engine runs a little bit warmer the ECM will pull fuel similar to how it does when EGT's become too high. I'm in Western Canada and when it is very cold this helps increase fuel economy a little on my 2015 F350 with a tuned 6.7 Powerstroke diesel in it.
The next question is how much are the modern emission systems costing in fuel. I've heard of people getting 5-6 mpg better after a delete.
On my deleted Ram, I’m only getting maybe a 1 mpg increase on mileage. But never hear all the weird codes come in when it’s cold outside anymore. 5-6 mpg extra would be a stretch in my opinion…
The 2008-2011 trucks saw a huge gain because they were the first generation of emissions trucks. Modern emissions engines barely gain any mpg from deleting.
@jellyfrosh9102 probably true to some extent, but I know of a 3rd generation 6.7 powerstroke that is getting at least 5 mpg better after delete and tune.
Love these mpg comparison vids !!
The added drag makes that tiny 3.0 engine have to work a lot harder. On that monster truck with the 6.7 liter, the added drag is almost shrugged off by an engine that powerful. Like what is the mpg difference on a 747 if you tape a brick to the belly vs taping a brick to seagull.
I watch this show even though I don't live in the US and will probably never sit in or drive an American truck.
take a vacation and rent one man!
Come visit. You don’t need all these trucks are offering to enjoy America. Perhaps you could rent a Jeep and drive the American West? Whatever you decide to do, I hope you come and check out the country.
I miss watching the IKE Gauntlet test.
With Mr. TRUCK AND NATHAN
@@Wicked_RotF30 Back when we could all dream of buying the trucks presented... tough times.
whats to miss they do it every weekend
Interesting. Was the differential ratio the same between this GM truck and the one you compared to?
Thank you for the video!
Morning TFL!!! Was just listening to ZZ Top-under pressure when this notification came up
I was listening to Laura Branighan- Self Control and when they said the prices of the trucks, all I heard was Hall and Oates- Can't Go For That😂
@@Wicked_RotF30 Friend called me yesterday...said he dropped $89.000 on a new truck..traded in his 2015 F150.
You guys should try the duramax 6.6
That AEV truck handily beats the EPA rating for a Diesel Trail Boss. I would really like to see a similar test done with 1500 (1/2ton) vs 2500 (3/4ton): if you're going to put a small lift and 35s on a half-ton, are you better off just starting with an HD truck, especially if both have gas V8s. The price gap between comparable light vs HD trucks is very small, and econ might just be a wash once lifted.
Anyone who will spend $88k on a 1/2 ton truck needs their head checked
Any different to $88k on an SUV, sedan or coupe?
Mary Barra is on crack.
Anyone making less than $150k needs to get their head checked; these trucks are targeting the new middle class, not the farmers/new lower class
@@Cloud30000 and how sir do you go about doing so
@@Cloud30000 Most people are buying these new as contractors or trades people for a business expense at $1200 per month at 6 year financing with $5000 down and getting the usual IRS/CRA 20% Gas Mileage and Business Expenses writeoff per year so in effect you're effectively only paying $988 per month for these trucks. That is doable for the average $60,000 USD ($80,000 CDN) per year 10+ years in business contractor or Journeyman hourly-paid skilled trades person!

Weather makes a HUUUGE difference on the 3.0L diesel. When it’s 45 or below I get 23-25mpg. The minute it jumps into the 50s I get upper 20s to low 30s easy.
Don't forget that when you put bigger tires on a higher gear ratio changes the gear ratio completely. Same thing goes for the other way around. Look on the internet for the gear ratio and tire size calculator
It wouldn't matter in this scenario. because it was a know distance traveled and a measured amount of fuel used. If they were going by an "un-corrected" odometer, it certainly would. It was also a much bigger issue on the old the speed trans, todays 10 sps, like in these trucks, are very adept at finding the right gear for the speed and load to stay in the sweet spot.
@@rts3613I think he was saying bigger tires will affect MPG because it effectively lowers the gear ratio.
Bigger tires is more weight, more rotating mass that requires more energy to get moving and keep moving. And stop. Yes, it effects your braking performance as well. This is physics 101. That's not even taking in to account added aerodynamic drag.
Great video guy's 👍 i wish you would of had a regular f250 against the tremor i think that would of been like the gmc conversion 👍
80k for a 1500 truck is crazy they should be in the 50 maybe 60k range
I get what you're trying to say, but let's be real, there is way too much technology and custom parts on that 1500 from GM to justify selling it for 50 or 60K lol!
😂when will boomers stop cryin
@@lonerider5315idk a lot of people in their 20s and 30s crying about things too. Like their Camaro dying off, Hemi gone, the Mustang not making dyno numbers, not being allowed to Carolina squat their trucks…
Taxes, emissions, regulations etc.
Agreed. I’d love to get a work truck variant with the 3.0 extended cab under 40k. I don’t want or need all the extra tech in these newer trucks. Heck, my current daily is a ‘15 Silverado with the 5.3 base model and I added a few things to make it better at towing. I mean at one point, before I did any modifications to it, I was routinely getting 24-25mpg from that truck. Granted that’s running 50mph too on back roads. But if the baby max can regularly get 30+mpg, I need a stripped down model.
EOG makes some incredible customized trucks
I wish they'd offer that style of AEV wheels for Fords. They look so good on the GMCs and Rams.
The Denver 100 reminds me so much of Calgary, Alberta, Canada that those two cities could easily be interchanged! The Highway 201 Ring Road that is entire within Calgary is 100 KM (60 miles) in length so that is our Metric Equivalent of this test.
If we want a the much more mountainous version, we have to goto Metro Vancouver in British Columbia, Canada and do the BC-1000 which is from downtown Vancouver to Whistler to Pemberton to Mt Currie to Pavilion to Savona to Kamloops to Chase to Sicamous down to Vernon and Kelowna to Merritt and Hope and then on Highway-7 back to Vancouver which is 1000 KM or 600+ miles of super-hilly, sometimes 13%-grades of twisty and windy roads that will have rain, snow, sleet, ruts and potholes and many times slippery sections them!
That 1000 KM (600 miles) is a total torture test of ALL trucks be they towing a load or not! That is one road that TFL needs to try as a lark with dually F350, F450 Superduty, RAM 3500, Chevy/GMC 3500 all towing 25,000 lbs AND the same route with the midsize versions towing 4500 lbs and the full-size versions towing 8500 lb trailers and carrying loads in the back-bedz only!
THAT would be the ULTIMATE tow and bed carry test for TFL!

Big difference in the tires in the mass of bumper on the F-250 haven't even watched this whole thing but I'm sure it's swell behind due to its aftermarket upgrades I've had multiple trucks and yes even leveling and putting 33s on a truck will eat the miles per gallon up
I love how people comment every video how pricey trucks are like they shocked they haven't changed since covid. Clearly people are still buying them so just chill. I'd love to see actual constructive comments about the actual trucks and not just guys bitching about the same thing.
I feel like such a looser. My truck isn’t lifted and leveled and loaded up with $40k in add ons. 😂😂
Is there any chance TFL could compare a regular 6.7 (non H.O.) on the same loop? Very interested if the H.O. is worse off.
If I had $120k to spend on a vehicle, I don’t probably wouldn’t think twice about fuel economy…
That's gnarly. My stock 17 Rebel is lucky to hit 15 on the hwy😂
Sold it though and now driving an LT Trail Boss Z71 with the Duramax. Average around 29-31 with steady hwy driving
Also cold and wet weather will bring your mileage down considerably. I would be interested in seeing warmer dry conditions comparison.
The price of the 1500 series trucks across the board is wild, 40-50k+ and close to 100k for top trims is insane, I can understand that for diesel 2500+ trucks that are built to run 500k+ miles, pull 20k+ and work for a living but prices are getting out of hand. In terms of the mpgs the lift does add some weight and mess up aero which hurts the efficiency a little but people forget compared to the stock road tires those LT truck 33-37" tires are like 20-30lbs or more at each corner and the tread pattern is not designed for efficiency when it comes to the rolling resistance on the road they really suffer there.
I would like to know what the Denali 3.0 would have done on the 112 loop. The 50-ish mile loop is definitely different terrain & traffic. I think the 30+mpg was uncharacteristic of normal Denver.
What about doing the super duty in Eco mode?
E-470 Thanks you for your patronage. I should do this loop with my F-350 Dually on 35s.
You should test the 6.6 duramax modified . Ciao from Italy
1st...thanks for the review!! Ford looks great.
@14:21
That analysis is inaccurate. Do gallons/100mi, not mpg difference.
However it still comes down to 27.54% vs 6.04% difference
with the price differential of $20K over the tremor the time to pay off is at least two more years of payments but your still paying $4.00 per gallon vs gas which is now about $3.50 per gallon in western Nevada!
Yet…you’re using less diesel fuel to go further.
3.99 for a gallon of diesel , here in oil rich northern Alberta we're paying about $ 7.41 a imperial gallon for diesel at most service stations .
Greetings from Lethbridge
3.55 in Texas
Here comes an issue with the MPG scale, as its logarithmic which means that the amount of fuel between each mpg is less for each mpg that you gain, so the difference between 16 and 17 mpg is probably similar amount of fuel as the 7 mpg at 30 mpg.
I do not like the bright red "Fire Extinguisher" looking liquid spring. I would prefer a brushed stainless housing. I know it would look like the others, but it works. And yes, 80k to 120k is crazy $.
So Andre… how happy are the manufacturers when they get the license plate toll bills haha
Ford definitely. Solid front axle > IFS.
We can all complain and argue that truck prices are insane, and that is true. But until all the lawyers, bankers, business executives, dealership owners, etc stop buying these luxury type trucks for themselves, wives, and kids. The prices are never going to come down. And the people who really need them like independent small businesses, ranchers, etc, won't be able to afford them. Even alot of the farmers have had to cut back on buying new trucks and equipment.
Since when has the price of vehicles ever gone down? There's a new benchmark every year and it will continue to rise.
Best way to get a lower price vehicle is to buy one when they are about to change to a new model. Right now Rams are discounted up to $20k, cause they are about to push out a new model.
Best way to look at it is cost of ownership from buying to selling. My most expensive Duramax trucks have been very affordable to drive with few problems and basic maintenance. I drive them for several years and sell them for a good price.
💡 *but when you lift your truck, the smiles per gallon actually increases* 😊 👍
Only a few people do this but curious to MPG on a truck that is slightly lowered....
Here’s a question, was the test done with Nathan using Ad-blue, if not, is this a fair test
My 2023 1500 AT4 baby duramax has lost about 3 mpg over the winter so far.
Tremor 3:55 gears 35” tires
Truck used here 3:31 gears 37” tires
Tremor with 37” tires world have been less mileage on that loop with the 3:55 gearing.
Enjoyed the video
No RUclipsrs work harder than you guys to bring us interesting content. Well done, all you guys over there.
umm this vedio ended
That loss for the GMC is not just the lift. The mud tires kill results (check out Trail Boss vs non-TB Silverado MPG), as does the 3.42 vs. 3.23.
Denver 100 logo versus 2003 Indy 500 logo 🤔😂
love the videos and all the info......but i think someone made a mistake on the half-ton measurements. 7 mpg is too much of a difference
3:31 rear end with 37” tires?! Is it idling at 55 on the highway?
Right where that 6.7 is happy.
I've never had the need to lift a truck. It's added wear on your steering components.
I left this one stock bc I barely fit into a car wash or the parking lot at work.
The prices are insane. I have a hard time believing the 31MPG
Diesel trucks when driven conservatively can get great fuel mileage.
I got 32 mpg out of that duracrap for the first week. Then all I got was 21 mpg due to the constant regeneration every 100 to 140 miles. My front dif did blow at 147 miles.
I sell the 3.0l in Silverado 1500s and lite footed old men get 30+ often on highway drives. Its the young wipper snappers who drive all crazy like that do not get that kind of fuel economy
@@michaeldemko8522 you’re completely wrong.
@@michaeldemko8522ok boomer
This was a great review, but Andre, I think you dumped some snow in the tank on the GMC fill up.
That is the DEF when it dries
It has more to do with the tire than the lift. Put standard highway tires on them and you will see a huge difference. It is the offroad tires that are causing the majority of the issue.
My dad had an F250 with a Power Stroke. Drove it pulling a huge 5th wheel for almost 20 years. Great trucks
You never mentioned the Tremor version
What time of year was the Denali Duramax run? Winter diesel is significantly worse for fuel mileage…you should know that being TFL Truck…
Whoevers truck that is owns a mini 🤏 sausage 😂
So what you're saying is you spend a lot of time thinking about other men's genitals, huh? LMAO
You compared the current 112 mile loop to a previous loop of only 56 miles. Not the same trip, not a fair comparison. Otherwise why not just always do the 56 mile test?
I've got a 2021 RAM 2500 + Carli lift on 37s. I get 19 mpg on the highway.
Yes and 22” wheels and 37” tires don’t help for rolling resistance. But you bought a huge truck, a brick on wheels, youre not really concerned with hyper-miling
If you think a F350 on 37’s feels like a luxury sedan you haven’t driven any luxury sedans lmao
That’s just about all he ever drives, where have you been? Just hyperbole for the video.
"They're not charging anything extra for this (diesel engine)" thats because they already charged 30k over the value xD you'd be losing money if you got the gas engine lol
If you remove the half acre of chin spoiler from a stock F250, your mpg might go down. Mines still on there, just waiting for a stump or a rock to do what they do.
The gmc is running a 3.23 gear not 3.42 for the duramax , not that it makes that much difference with the 10speed transmission
would have been funny if one of the trucks went into regen while in the test.. 10 mpg
I can confirm that lifting your gas F250 does absolutely ruin your MPG. I'm lucky to get anything in double digits.
winter diesel vs. summer diesel?
It is a thing. Diesel can gel when it gets too cold. Diesels are cool but they are not cheap. Unless you tow a lot, truly haul heavy things or you just got it like it, it really isn’t worth it.
That Ford is pretty awesome!
Andre is that snow, or DEF crystals around the fuel fill? If thats def. Get it out of there, you really don't want some kf those crystals in the diesel fuel.
80 psi tires sure help mpg.
Thats pretty descent gas mileage for lifted full size diesels, my ‘22 Frontier only gets about 22mpg, but thats combined.
Winterized diesel gets quite a bit less mileage than your previous tests in summer.
Winter fuel is going to massively effect this test
Absolutely stupid truck prices!
My TRX gets 10MPG on a good day.
Very cool. Meanwhile my 23 Tundra 1794 Hybrid with the TRD Offroad pkge, 3" Totoya factory lift, RCI skid plate, Icon rims, and 35x12.5R17 Falken Wildpeak RTs is averaging 13-14mpg in mixed city/light highway use. It does have a 100lb aluminum tonneau cover as well but still 13mpg? Pure highway driving gets me 17.5mpg on a good day. I need to move to 35" KO3s to lose some rolling resistance weight. Though I love the RTs. This is before I put on steel CBI front/rear bumpers and a winch. So I guess then mpg will drop to 11 combined. Something feels off lol with my Tundra. I do live in a hilly area but still.
I think most of us watch and wish ! Who can afford such trucks ! I'll stick with my 2011 RAM.
Pretty sure the AT4X AEV is heavier than the Denali tested also, so maybe there is some of the difference.
Was the gear ration the same as well?
@BigRedbabymax
earlier posted "The gmc is running a 3.23 gear not 3.42 for the duramax , not that it makes that much difference with the 10speed transmission."
Fyi liquid spring suspension starts at $20,000!
I’m genuinely curious what market these 120k trucks are targeting…is it just rich people who want a lifted heavy duty? I can’t imagine the work scenario that requires or is helped by modifying those trucks for that height. I could be wrong though
I like how he listed the base price of the F350 with no options on it. Look above his head at that sunroof, lol. At least the GMC AT4 comes fully loaded, still overpriced though.
Did you say the GMC was a 1500 anywhere in the video?
Why would he? Anybody watching this would clearly know it was a 1/2 ton truck and a 3/4 ton truck. If you don't, you have no business driving one. That is why prices are threw the roof.
These mpg loops are a joke with such short drives, better to not do them at all than generate some of the bad data they do here
You can get a fully loaded DENALI with the 6.2 in my area for $80k-85k...why on earth would you spend basically $90k out the door for the truck with the baby diesel and some offroad add ons?? Idk I don't prioritize serious offloading like some others out there so I'd much rather have the better equipped truck with the big V8 for less money. Plus the 6.2 is cheaper in the long run, the mpg isn't as good but its not far off, my uncle's '21 6.2 gets around 20 mpg but you don't have the DEF costs and increased oil and maintenance cost of the diesel either.
Why would anyone spend $80k on a Denali with a 6.2?
I bought my 2020 Duramax Denali 2500 brand new for $70k. Today same truck is $92k+. Great truck, but no way its worth that much. These prices are high because people are willing to pay it.
No mention of gearing differences. Aerodynamics and gearing probably cause the biggest drops in MPG. Weight of add-ons, not so much.
Aero figures more the faster the vehicle goes. The weight is the KILLER in city & hilly driving.
That 31 mpg was a red herring...
I’d take the v8.
A 3.31 in the Ford, that would seem undergeared. A 3.73 would be more normal.
That f350...175k canadian, that's getting into raptor territory (185k)
“A straight 6 diesel meant for highway cruising and (maybe) pulling a trailer”. Uhh come again. Yes because a semi with an x15 is meant for highway cruising 😂
Winter diesel
I think something that everyone is forgetting is that these new trucks have dozens more features than what they did 10 years ago. More features more equipment more. Cost
You can get an affordable truck at $41000.
As long You get the custom trim but every one wants all those features.
I mean come on heated steering wheel air-conditioned seats? Trucks never had that stuff now they do but You're gonna have to pay for it.
31mpg on a pu is insane were the trucks 4wd?
Every mouth breather lifts or levels their truck and puts on big ass tires. Then they commute and go to the mall.
put 3.73 gears in both and there will be on stopping you.
What it would be great is get a stock truck and then compare it to a lifted truck. But it has to be the same brand. Need to compare apples to apples and not apples to oranges. Otherwise the test will be off. Even you can explain it to the best of your ability, it still won't be an accurate/true test. Because how can you compare, for example, a duramax lifted to a powerstroke lifted. They were not made similar. One brand is made different than the other. So to make it comparable, need to get the same brand. One stock, and the other modify. To see the difference.
