Charlie, I like the way you cleverly slipped in a HD Pickup parking tutorial at the start of the test. The mpg itself is rather impressive but as an old timer, I am reminded that low emission Diesel engines are very much a work in progress. It is like we are reliving the first decade catalytic converters were introduced to gasoline engines. 🤔
So true!
Something else to consider, winter diesel has a different formulation to prevent gelling and will give you slightly less efficiency. Interesting to see the same test in the summer. Good video
Thanks for the info, i have a 3500 hd Gmc 2014 edition and get 17-18mpg on my duramax
loved the video, very underrated channel
I have a 2022 2500HD LT Silverado and this is the mileage I am seeing at 75 mph. I tow our trailer through the Rockies and no problems getting 12 - 15 mpg as long as we keep it at 65 mph or less. Best I ever got 36.4 mpg at 45 mph.
I drove one of those 2800 miles this week, 19-20 with no load, and with 2000lbs in it 17-18
I daily drive a 2020 on the highway in Texas. Unloaded I average 14. That’s going 80+. Don’t expect to average 20 at highway speeds.
Awesome 👏 video
Very torn on what to get. I don’t tow at all and debating to get 24’ 2500 duramax or just get the gas model instead. Seems like the duramax has wide mpg numbers from 15-20 depending on driving. I’ll mostly do city driving
Thanks
I'd be really curious how it does at 80
I have a 2022 Denali Duramax and I have owned 8 duramax trucks since 2005 and this truck does have plenty of power but MPG is not good at all compared to previous models. I average 11.6 in the city and maybe 15 on the Hwy and towing my side by side I get 11.4. which really stinks . I have also had a 2020 1500 Duramax and it was getting 15 MPG pulling the same trailer and side by side and it didnt struggle pulling it. .
Have 2 2023s. Same thing. Crappy mileage. My raptor gets better mileage towing my smaller trailers.
I want one so bad, i don’t tow anything but id still like one just cause how it sounds 😂
Dont let this fool anyone shopping on of these. They average 14 mpg running around.
I have this exact truck and it can easily get 17+ with city driving when unladen. However, a 50 mile sample that had a regen in it would be a different story.
@@GSNpaladinZero lol,ok.
Running around? As in like, city driving? Not interstate driving?
I have the same truck and I avg. between 17 and 19.5 most of the time with normal driving, around town and county back roads. 55-65mph, no highways near by.
Thanks
As soon as you slow down and speed up a few times it drops to 15 then you stop at a stop sign and it’s at 14 and stays there…highway mpg doesn’t hold long add a small 5x8 cargo trailer-13 mpg-6x12 cargo-12 mpg.like clock work for 13,000 miles this is what I get
Or better yet, just do a calculation over a couple-week period, 1 whole tank, but SOMETHING better than perfect conditions for 50 miles. All the channels do this; it’s pretty frustrating!
The MPG is suppose to get better by like 1 or 2 mpg once the truck is broken in so you should do the test again in like 5k miles and see if the result is the same or not.
Mine did and it was noticeable. I've also been using Hot Shot's Secret EDT and am seeing an increase of about 1 mpg at 30K miles.
@@robertcolpitts4534 Didnt know that stuff actually worked thats cool
@@anthonyj810 - It does. Only takes an ounce every time I fill up. The engine runs noticeable quieter and smoother with a slight increase in mileage. I was skeptical at first but it does work.
The at4 half ton has a 2 inch lift from the factory. the hd version’s don’t have a lift they are the same as all the other gm hd’s with the x31 off road package. Basically all it is a skid plate package rancho shocks very tame all terrain tires oh and red tow hooks lol
EXACTLY!
And no ugly chrome.
That truck did not even feel the hill going I 70 to Denver , idled up steepest grade,
I average 22 mpg at 80mph in the city average of 14-15 and combined 17-18
I’d like to see an F-450 that’s the next truck I’m looking at getting
22 mpg at 80??? In what?
@@jaysson1151 2021 GMC Sierra 2500 Duramax
2020 Sierra 2500, yes 22mpg at 80mph. Drops to 11mpg when i hook ANY trailer, have 5 from 1,000 to 14,000lbs.
I was just saying compared to what they got on their highway loop. I’m getting phenomenal fuel economy for as heavy as it is
gets better mpg then my ram 1500 lol i get 16 on the highway
I average city and interstate 28.6 mpg in my 04 lb7 gmc 2500hd. The "low emission" stuff is a bunch of crap the government doesn't need to be involved in.
Why is the mpg that good did u do a muffler up grade ?
I have an lb7…do you have a tune because if I go 55 downhill I can get 22-23mpg
@@jonnyg9330yes. the tune makes a huge difference, disconnected/uninstalled I get around the same numbers your saying.
@@roxastherogue what tune
Fantasy land .
really pretty good MPG, this is what diesels do best. Just make sure you actually need it lol. they're expensive to buy, expensive to run and expensive to fix.
cold air intake would get like 3-4 more mpg
There’s something about pumping diesel that makes it fizz so the pump goes off sooner than it should. So that may be why you go the higher mpg number on the calculator
In theory, the three-click method should allow fizz to die down, but it’s possible.
It should fizzle when it was filled up last too though in theory. As long as it is filled to the same level the numbers should be precise no?
Try filling until the nozzle clicks then wait 30 sec, then top off until it clicks. That's what TFL Trucks does. It works.
The high tire pressure is causing your instability on highway
24.3 mpg hiway in my 2018 ford f-150 2.7L w/ 3.55 axle. Keeping it at 65 to 70 mph.
I don't know where you live and drive but down here in the South, you'd get ran off the road going that slow. Is your truck a 4wd? I'd be lucky to get 19 in my 2012 3.5 Ecoboost 4wd with 3.73s in the summer time. Plus I don't see a difference when going 70 and 77. If you go too slow while it's in overdrive, you lug the engine, forcing the turbos to push a lot of boost without locking out an overdrive gear. When you go too fast, the wind resistance really starts taking its toll. There's like a balanced sweet spot where you're hardly pushing any boost and the NA horsepower is enough to run efficiently without working too hard against the wind.
Lol
But the fuel savings will be offset by the blown headgasket 😂
Some of these people are getting different # s with same year trucks. Fantasy land? 14 around town . 18 on highway is where it's at
If this is stock, These trucks are not lifted from the factory.
hi, are you 100% sure it didn't have adaptive cruise control, its on the steering wheel. if you have the tech package with the 15 cameras I know it comes included.
You can NOT get adaptive cruise control on current GM HD trucks.
Certainly not on an 04?
whats price tag in this ?
$2000000 pesos
20 MPG in the diesel, is the diesel worth the $10K extra over the gas engine with the gas engine getting 15 MPG? Even with diesel being $5 per gallon?
That's the $50 million question! I guess it's only worth the diesel if driving range per tank is what you're more worried about. There's nothing worse than have to pull your bigass trailer into the "pedestrian" gas pumps with all the other cars and mom-mobiles instead of the truck lanes every 200 miles. Plus there are aftermarket fuel tanks available but for diesel only.
Diesel means more torque + diesel exhaust brake. It's also fuel economy when towing + when empty. That gas version also has a shitty 6 speed that can't compete with the new 10 spped Allison in terms of smootness. Can't compare only fuel price.
@@liberteenfamille3191 Right but you also have the $10 higher starting price plus the maintenance costs of a diesel. I guess if you tow over 10K lbs every week the diesel probably is the way to go.
@@liberteenfamille3191 yes the gas version is hamstrung by that 6-speed as well as the 3.73s. At least the old 6.0L Vortec had 4.10s with the 6-speed. That was a bulletproof combination. If they would at least offer the 10-speed Allison and more gear ratio options the same way Ford does with the 10R-140 Torqshift with the 7.3 Godzilla V8, then it would be a much more capable truck.
If you're not planning on towing heavy for long distances and you're just needing a 3/4 ton for its payload and better towing compared to a 1/2 ton, then the gas engine will do fine. A diesel is overkill if you're gonna occaaaaasionalllllyyy tow something more than 10K but less than 16k, especially on mostly flat terrain. Just look how the 2020 F250 7.3 GAS V8 with the 4.30 just manhandled a 20K lb trailer up AND down the Ike Gauntlet. You're gonna tell me that's weak sauce?
@@311hitwall I am a diesel mechanic and do some light excavation on the side, my trailer loaded is 18k lbs and guess what? Gasser all day. I have a 12valve too but normally 3-4 times a week use the gasser. Emissions diesels are for people willing to pay the costs for no return on investment unless you are a hotshot trucker where the fuel savings really adds up doing 100k miles a year.
I have at4 2022 at 65mph 105 km/h i get 22.3mpg 10.3 l/100km. Making range of Diesel anything over that speed of 65mph will loose econo... also i'm in the northern ontario we have grade A feul mabe that has to do with something.... cheap southern diesel dont run here from november till may mabe that effect the rating...
Bull everyone gets same mpg 14 around town 18 on highway going over 70 miles an hour . Fantasy land
ICE BERG
Math don't lie trucks do
That's not real world, try using a full tank of fuel
This further proves my point that the Tacoma is junk. A midsize truck with a v6 got 20 at best. And this HD gets 20. Had a 2018 megacab 3500 that could go over 500miles on a tank. Tacoma…barely 300
The interior looks quite ugly compared to the new refresh!!
Refresh is coming in 2024
If this truck is so awesome why is it always in third place in sales every year.
Is it really 3rd place? In my area there's so many of these. I ordered an AT4 2500 a month ago after spending a lot of time looking at all 3. I really felt the GM/Chevy with the duramax was the best package out of them, that's just my opinion though.
@@kruegermachiningltd4355 You're right, especially with that new 10 speed Allison.
Well I don't worry about fuel mileage. I had the money to buy my 2500 hd denali so fuel mileage isn't a concern. If you are worried about fuel mileage join Biden an the communist democrat party an drive electric an pay twice as much in electric costs.
I got an old diesel honestly for the mpg. Towing and not, I average 28 with mostly highway driving.
Biden plans to phase out gasoline and diesel motors. A lot of gas equipment is starting to get banned i.e California and the rest follow.
@@roxastherogue ive never really checked mine. I drive a big truck and im gone 3 to 4 months at a time. My GMC is 9 months old an I've only put 700 miles on it. Its my retirement pickup. Lol
@@thomaswilson8634 enjoy good sir I hope it treats you well!
Using about 200kwh a month a tesla only cost on average 30$ a month to drive about 600miles! Your math is about as bad as the Trumps!
@@ponce1521 thats good I like The Trumps. Made me a lot of money. I lost money with Obama so im a Trump fan for sure. Love that math
I'm thinking if you can't even run through an entire tank or two, you're not really trying. This is just for you to have a video. Not a good video
An entire two tanks of fuel at steady state highway speeds within one week of having the vehicle? I'd never make my money or time back.
I'd be really curious how it does at 80
