#chevy #silverado #duramax - Auta a dopravní prostředky
For that big and heavy of a truck, 18.1 mpg isn’t bad at all. I have a 2022 LT Duramax and I’m at 16.9 at 10,600 miles and that includes towing. I’m usually 18-18.5 not towing. My display is pretty spot on with the pump. I really can’t complain about that. My 04’ Expedition used to get 12, so it’s still a big improvement. The 35 gallon tank seems to be a really good size and offers a lot of range. Sometimes I only fill up once a month.
Gale Banks has a great video showing the updates to the engine. One of the biggest changes is stronger valve springs for more engine braking.
Agreed. That was a cool engine video.
I watched it the other day, good video for sure
Did you see the Banks Power release where they do 3 Dyno runs with the 2024 GMC. Pretty informative !
The pistons were a lot different also
If GM wants a better engine brake they need to add more than just stronger valve springs....
Thanks TFL for making all these videos!
I get a pretty decent mpg towing for work almost daily with my 2023 Silverado HD. Helps that it's a diesel ofc. I like the looks of the 2024.
I have 6.6 duramax history In the past . I had a 2013 Chev duramax diesel. Beautiful. It drove perfect and with grace and power. I’m in the market again for a
2024 Chev 2500 diesel duramax 6.6 L !
GM has always been known for the best ride in the HD market. Independent front suspension is a big part of that!
And the reason I will never buy another GM HD truck until they change it. There’s a reason the others have trailing arm/link coil over suspension. That torsion bar shit is unbelievably outdated and is just garbage for an HD truck. I’ve owned two so I’m not just armchair quarterbacking it here ans do not have any brand loayalty. I go with what impresses me and is more sound mechanically. I’ve had a new Ram 3500 each of the last five years and they honestly were great. However, now that the Ford has changed the interior and given the Powerstroke another bump that is what got me excited. Granted my Powerstroke has 2300 miles on it but I’ve already ordered a 24’. I’m very impressed with the HO motor and that takes a lot.
@@specforged5651 I've never had a front end suspension or drivetrain issue on a GM pickup with independent front suspension and that is over half a million miles! I tow 90% of my driving anywhere between 7k and 17k lbs on a variety of trailers with the biggest being 38' Grand Design fifth wheel. Can't beat how well my independent front suspension rides instead of old outdated solid front axles!
I have a 2022 Duramax Silverado 2500 LT and I really like the independent front suspension. What sucks is Ram trying to use it for the rear axle. That’s why their payload is awful and they squat so much.
Another previous owner here, yes IFS rides better but didn't last anywhere near as long without expensive repairs, never again.
@@gabrielback5615 My experience exactly. And honestly I wouldn’t say they ride any “better.” I think better is a relative term. Better to me means solid, tight and like a one ton truck should ride. They appear to ride smoother because they have lighter duty parts in them. Not to mention they have so many connection points, bushings, rod ends, etc, etc they start to feel loose, make a lot of noise and wear tires in a short time. The Fords and Rams just feel more solid and robust. Stick your head under there and it’s easy to understand why.
Great video! And I have a suggestion. It would be nice to see a comparison chart at the end of the video of previous generation trucks. Ford and Ram as well. This could be with all your videos, including the Ike Gauntlet and anything else. Thanks!
Got me all excited thinking it was the 6.6 gas with new 10speed. Hopefully you get that video up. Thanks.
I love your CZcams channel
I drive a 2021, 6.6 Duramax. My fuel mileage got better after 25k miles.
I think that’s pretty good fuel mileage I think they get better after they get ran in
For a engine that most likely isn’t broken in not bad mileage. I see the MPG just getting better as the engine is broken in.
My 2022 Duramax mileage went up a lot after break in.
My 2022 has 10k on it, and it keeps getting better. I also dropped a titan 56 gallon fuel tank under mine. I tow a 42-foot fifth wheel and didn't care for that small tank...
@Chuck Neil what will you consider breaking in mileage? I only have 1K miles in mine..it's great to think that mpg will get better
@@Pantelifts10 My 2018 GMC 3500 HD didn’t start getting 15 MPG city and 24 MPG Highway until almost 40,000 mileage. I just got a 2023 GMC 3500HD and day 1 Highway MPG was 17 and 14 MPG city. I now have 1,100 miles on my truck. I would think that the break-in would be about the same. Keep in mind these numbers are not towing numbers. Trust me when I say you will be happier with your diesel than a gasser. I had 2 GMC 2500 gas trucks and never got more than 12 mpg city or highway. Towing mpg was never better than 5 to 6 mpg, only got 6 mpg going downhill. JK about the downhill commit.
@@Pantelifts10 If you're at a 1000 miles you should be able to start towing heavy
Great data point. I think a longer run that includes a regeneration would be more indicative of real world expectations. My guess is (like Ford) it will stretch it out on the highway and suffer when in stop and go and hills. Regenerations will definitely have an impact, but curious about how much of an impact. My 2022 Ford F350 CCLB with 6.7 has impressed me over the last 3400 miles (since new).
Seems pretty solid to me. Likely better than my '15 Sierra 1500 6.2 with level and KO2s.I'm happy when I get 18mpg on an all highway trip.
I leave a lot of negative feedback in the comments, so I always try to make sure to give positive when warranted.
This was a great video. Precise language, informative, not wasting my time rambling on about stuff of no importance, a reasonable length for the content provided.
A+. More of this
I’d like to see TFL undertake a long/term 3-5 year longevity test that focuses on HD Diesel reliability between the big three brands using real world use over an extended period. The KPI’s to include reliability, regular maintenance cost, tracked warranty issues, one-off maintenance cost, truck performance, and trouble free motoring. For $80 to $100K purchase price of todays vehicles, we consumers expect greater reliability included in these vehicles. No more junk GM, Ford and Dodge.
People would rather see content of new vehicles. Long term info likely can be found on forums with owner updates and reviews and fuel economy generally tracked on Fuelly.
Long term reliability for single items isn't really a fair comparison. If they had 20 of each, that would be a slightly better comparison
100% agree! =)
Another great vid Andre.
I’m waiting for the 6.6 gas VS the Ike 🦾🦾🦾
Yes we need that video and the towing mpg loop
I have a 22 with about 30k on it. A couple weeks ago, we drove from NC to AL, about 340 miles, and I made myself stay near the speed limit for a change. I averaged 22.6 mpg on that trip! The truck is unforgiving when I get on it though, it typically does 18.5-19-ish with city driving or steep hills. Gets 10-12 towing 15k#.
Unforgiving? Even that city/steep hills mileage and towing figure look amazing.
Try driving in a city like nyc and the mpg will look more like 13mpg it’s a shame they don’t rate the gas mileage in real cities instead they go to a small town and say that’s city mileage
@@king502NB Oh I have, there, Atlanta, Boston, my job takes me all over. And I think idling in traffic is almost as bad as hauling butt; you can see the number dropping while you sit sometimes.
@@ALMX5DP I mean the sharp drop from 20+ when things get less mellow. It does well for a 4 ton ox with a turbo V-8, but will bite you quick if you get in a hurry or want to have fun. I’ve towed several times in the mountains of KY, TN, WV, VT, NH and the uphill grades seem to subtract efficiency more than the downhill coasting adds. When I’m going downhill or level I will often turn off tow/haul to lower rpm. I calculate at the pump, too.
The manufacturer doesn’t rate the mileage. These are heavy duty trucks.
To me that mpg isn’t bad. With the emission systems the MPG can greatly change with regens. I’m also curious about the gas engine mated to the 10 spd. I see that being a great benefit to the gas engine!
I heard that the 10 speed tranny for the gasser is different than the 10 speed behind the Duramax.
Can someone in the know either confirm or dispute that one?
I haven't drove one but I feel the gasser and 10 speed would hold back the gas engine 4stroke Gas engines have a huge power band
@@VLK-73pretty sure they are the same exact transmission.
@@XploreAztorque converter will definitely not be same, the rest maybe
@@chanceheimann919definitely wrong on that. Na v8 gas engine have a horrible power band only make reasonable power above 60% of their rev range
Had a 2001 Duramax 2500hd 2wd. Got 21mpg and 31mpg with a custom tune download. She ran over 500,000 miles before needing a overall. Best truck I have ever owned ❤❤
Before the govt crippled them
My 2011 1/2 ton Sierra with small lift kit, 34 inch tires at 65 MPH on level surface can barely manage 18-20mpg. For this truck to get 18mpg is impressive.
Now do it towing 17,000lbs.
Also, you guys should do payload testing. You always test while towing but never test solely with max payload. Some people only use their trucks for hauling but dont tow.
The Canadian guy does it on his channel. I agree I have about 1500lbs permanently mounted in the bed plus I tow a mini ex and dump trailer. What brand you drive?
They did a max payload not that long ago on the ike
They do. You obviously haven’t watched any. They do tests pulling the Guntlet out west. Its literally the steepest grade to climb in the rocky mountians
My 2020 gets 8 mpg pulling 19k in the mountains....... very steep mountains
17k? How about a GCW of 37k with a SRW? Depending upon the height(wind load) of the load, I can get anywhere from 6-9mpg with my 21 F350 on I80 through Pennsylvania or up Monteagle to Chat.
Love the review!
Thank you!
My 2020 regular cab 4.3L 4X4 1500 would have pulled the same number. This is very impressive, adding 4 additional gears really helps.
I’ve always liked that 4.3 engine. They’ve always been reliable and offer decent power and efficiency. Something about a big 6 cylinder revs my engine. I loved the 4.2 inline 6 (275hp/275 torque) in my 04’ Trailblazer. It was the 4-spd auto and super long gears that held it back.
@@alanj7306 reliability was the main driver for me. I never kept cars for a long time. 2020 broke me of that bad habit! So I bought for long term instead of instant gratification. That’s why I’m looking at HDs for the next truck because of the robust nature but I have no interest in turbos unless on a oil burner.
As time goes bye it only gets better, that’s my experience with my truck.
These loop tests are instructive but there are a variety of factors going into mpg. What I've found on my '22 GMC Sierra AT4 6.2L here on the Gulf Coast (low altitude) is that speed is the single biggest factor affecting mileage. Around town the 6.2L does ok, 15-16 mpg avg. Hwy figures at Texas interstate speeds (80+) only improves to 17-18 mpg, but if I'm traveling 2 lane country roads at say, 70 mph or less, the mileage jumps to 19-20 mpg. I think the ride height w/ 2" factory lift is a big culprit. Can't fault the GM engine or the 10-speed auto... they're a wonderful combo.
Yeah these loops only tell so much. You’d have to have all vehicles you’re comparing it to drive in a single file line at the same time same route to be able to compare MPG. My 21 Cummins HO will get over 20 on two lane highways, but that’s not to say the others wouldn’t as well
Same for my Silverado ZR2
this truck has the same mpg as my 2008 acura rdx that averages around 18-19 mpg. this is impressive for this size truck
It's crazy how fuel efficient these trucks are getting I love it! My 5.0 2022 f150 averaged 24mpgs on a trip from Raleigh to Asheville NC. 26 mpgs in eco mode doing 60 to 70 mph.
Have you adjusted your AFE bias, or is that hand calculated?
@ALMX5DP real world tested.
@@malcolmn.5222 I presume that to mean hand calculated at the pump?
do you know how much a chevy with afm does
It is crazy, my 2021 3.0 duramax silverado gets 26 city and 33 highway lol. I've done trips where I have a tailwind and I'll get 35.8 mpg over the 120mile ride lol.
I drove my family members 2019 duramax empty no wind 120 miles which mostly highway and I got 24 MPG. I towed 13k 5th wheel on my return trip and got 12.5
My boss said as soon as he hooks his 7 way plug in on his trailer it instantly drops his milage lol- trucks got 475hp and it can't get good milage towing , quite sad and I'm a duramax fan for life
Just got the oil report back on my 2006 LBZ 3500 with 210,000 miles on it: Perfect! I'll check again at 300k.
Nice one!
My 2005 GMC Sierra 1500 gets just over 12mpg with city and highway. 14mpg+ on a good day with the best I’ve ever got being 17mpg+ driving 55mph with no wind.
Do a review on the new LZO towing!
Would like to see how this mileage compares to that of the 6.6L gas with the 10 speed tranny.
Banks has a video analysis of this new engine in comparison with the old one
First thing I noticed when switching to powerstroke to duramax was the mpg on the highway was really really good much better then the powerstroke but my city mpg is trash
2022 Ram 2500 with the 68RFE has 100 miles on it did a 150 mile run similar road conditions the truck had 20.5. calculated mileage was 19.8mpg. not bad for new and the 6 speed tranny. I just went from a 2017 Duramax with the 6 speed alison which was very similar mpg. Like both trucks..
Is that 68RFE still alive?
My 2016 LML, before I put 35s and a lift, would do 23-24mpg on the highway. I thought that was crazy good back then. Driving in town and highway mixed, I’d get 15. So to me, 18 is amazing.
What is your highway mileage? If you're getting 15 in mixed driving, sounds like you could be fairly close to 18 on a pure highway cycle no?
@@ALMX5DP no sir. I swear on my life, doing 65-70 on the highway the truck was getting low to mid 20s. (When it was stock at least) Where I live trying to drive thru town was stop light after stop light. So my tank averages were coming out to about 15.
@@Mattss90 I mean with the lift and tires. If you’re currently getting 15mpg mixed driving, what is your current highway economy?
@@ALMX5DP ohhh. Those were stock numbers.
With the lift and 35s’ I’m getting 10 around town and 15ish on highway at 65-70. Maybe up to 17 if there’s a tailwind
@@Mattss90 oh gotcha.
Banks tore down the 2024 diesel already to analyze the changes directly to the 24 6.6 DuraMax vs the 23. They had both versions torn down.
He said the 24 is a much better design. He really was positive of the changes.
Banks also dynoed the new GMC Denali Ultimate. He looked at it differently than usual as it was not possible to get the stated max at 1600 rpm as the transmission downshifts to 2150 rpm between shifts and not 1600 where the peak flywheel hp is.
He was still getting big numbers. Especially the torque numbers he got suggest that GM is underrating these motors. Less than 75 lb ft of torque lost at 2150 rpm (torque has already peaked and is dropping a bit now) vs the 1600 max. About 7% loss vs the typical 14%.
Regardless, they make everything they claim at least!
Banks also felt that the design was capable of being more fuel efficient and is a cleaner burning engine. Maybe lass DEF use?
Pretty nice truck though… and I an a Ford fan. The new interior is definitely nicer than Ford’s. I prefer the GM interior over the Ram as well. The Ram’s 12” screen is gaudy in comparison. This is definitely subject to personal preferences.
I did think the DuraMax would have done better but this is still a very new truck. Based in the Imperial gallon that 18.4 is actually 22.1 mpg imp. I was hoping for 24 mpg imp, so close enough for now.
Still prefer the 6.7 PowerStroke even though I don’t own one currently.
Good looking truck
For dragging air sound right
With having an average speed under 40mph that sounds ok. I was more interested in what it averaged on the highway. My 05 2500hd 4x4 consistently got 22-24mpg on the highway as long as I was nice to her. I expect this truck to be better than or at least even that. Especially with 10 gears.
Just traded my 2023 gasser in for a used 2022 6.6 diesel. It has 50x miles the overall milage reads 18.3
My 6.6 gasser was at 12
Love it...Awesome truck , so much better than electric truck. I would like to see a challenge been a gas or diesel truck vs a electric truck. I know the gas truck will win by a long shot. Electric loses so much range once you put it to towing or even turning on the a/c or heater you lose half the range.
Doing a mix of city and highway (more city than highway) i get 7.2L/100km (32.6 MPG) in my 2020 Chevy L5P. The only thing I do is add Stanadyne to every tank and it makes such a difference. Before using it i was getting about 9L/100Km (26 MPG) doing the same driving. Compared to my 05 LLY the mileage is just about double for the same amount of fuel and the truck sits much taller than my 05 but is still a crew cab short box. Talking with several diesel mechanics and a place that all they do is rebuild diesel fuel system components they say Stanadyne is the best additive for diesels hands down, and i can attest to this as I have been using it since 2008. Would love to see someone do a test on a vehicle with about 20 000 miles and do 3 tanks without and then do 3 tanks with and see the results.
Not bad but my 04' Cummins 2500 with 272,000 miles, auto 5 speed, 4 door, long bed gets that around town. Like any vehicle, after a good break in period, you find the sweet spot for that truck. Know when to accelerate easy or hard depending on the conditions. I have noticed in 8 speed vehicles if you accelerate quickly in the lower gears, the engine is easier on the fuel consumption.
Please do the 3.0 LZO Duramax!
Makes me feel so much better about my 6" lift 35" tires 2007 duramax getting 16 mpg on the highway.
Should be able to get 18 mpg with good tune.
I have a lifted 2022 3500 Duramax with all Banks, turbo pipes, cold air intake, exhaust on 35s and get 22 mpg at 80 mph. I think you need to do another test on a calm day.
Have you done this test on the gas 6.6?
My Powerboost has only averaged 19.6 mpgs after 14K miles here in eastern U.S . Mostly highway at 75. Does better in city of course. Huge amount of torque but I desire a truck with more payload for a small truck camper some day so these videos are very helpful.
Does better in city? Not normal
As a truck driver, I see those new Ford powerstrokes on the side of the road looking for antifreeze just about everyday.
Now I have a 2020 chevy Silverado 2500hd duramax, I can easily get between 22-23 mpg empty (best is 26), and 11-12 pulling my camper. Vary impressed with that truck.
Great video, as always Andre.
I’ve always wondered why the mpg numbers from the pump flow totalizer instrument & the odometer are the baseline and not what the vehicle computer calculates from the vehicle instruments.
Do gas pump instruments get calibrated more often? What’s the logic for believing the gas station measurement of gallons delivered to the tank over the number calculated by the vehicle?
I suspect the fuel gauge is not as accurate as the pump since it is going by an approximate measurement and is not legal for trade. There is also the possibility the refill amount is off by a tiny bit as well. All in all I suspect they have a very good system of keeping things as close as possible on their tests which is why I come to this channel looking for information.
Sinclair fuel stations look identical to BP stations here. BP used to be Amoco here. Just rebranded in other parts of the country I suppose?
I ain’t gonna lie, I’ve owned 4 GMC Sierra 2500 Denali trucks, but the High Country looks great!
My 2021 will average about 17-18 mixed with a light foot. 20-21 mpg highway.
Cummins can also be optioned with 50 gal fuel tanks.
Did they fix the trailer TPMS of only 100psi? What about the bed camera, can you zoom in for hitching a fifth wheel?
My next truck
Have you noticed dead pedal in the 24 Duramax? I just did a test drive on a 24 LTZ. From a dead stop if you hit the throttle quick at least 1/4 or 1/3 down, it had dead pedal for almost 3 seconds. I mean i hardly responded then hit real hard. Also driving around the diesel just didn't seen responsive till it spooled up. I found it rather annoying. Seemed like a lot of turbo lag. What's your experience? Did the truck learn and improve?
Does your truck have a tonneau cover those for sure work
I just ordered my new 2024 LTZ. Thanks for the mileage test. Now that I have it the truck gets about 16MPG around town. If I keep it under 75 MPH on the highway, then I'll get 20MPG on the highway. However, if I go 85 MPH the mileage tanks.
Really?!! I drive like a granny with the same truck and get 12/13 in town and 15/16 on the highway. I live in flat north Texas!
@@ArtbyLordTV I do use a fuel additive and oil treatment. With a tune and new turbo I expect to pick-up another MPG city and highway. Then I'll be where I was with my old LML which had a few tweaks. I expected the Allison ten-speed transmission to be more helpful mileage wise, but it isn't. I'm sorry about your mileage.
Yeah I swapped out the intake for a cold air, I use cetane booster and still crappy. I did throw a code in the first 200 miles about the emissions system which GM said just to clear and send back. Wondering if it was really a problem and they just ignored it
@@ArtbyLordTV I remember reading there was a problem with the DEF system. The dealer salesman said I should only use GM DEF. But, even the low-cost Walmart brand DEF meets "API regulations and ISO 22241 standard for purity and concentration." So, BS on that! I installed a 100 GPH FASS fuel system on my LML and will again on this L5P. It helped more than I thought it would. Expensive, but worth it! Right now I just have a K&N air panel intake filter. I use the Power Service and Lucas fuel additives. The oil gets ZMax.
Do a test with the 6.6 liter gasser with the 10-speed
Are you going to cover the ecodiesel recall?
Glad they kept the column shifter...Nice.. Thanks Andrey.
I would love to have the 2024 silverado with a 540 cubic inch big block and the Allison 10 speed and maybe add a procharger it would be one great truck then!!
Would like to see DEF consumption too.
mr truck what is the mpg on the 2024 silverado custom z71 diesel pickup truck
can you do one for the 2024 6.6 gas now?
Custom ordered and received a 2023 LT Gasser. Watching this series more I feel I got the better truck. I don’t tow massive trailers though.
I've got a 22 gasser and love it!!
Why?
better then my 1/2 ton
You had a 10psi difference between your front and rear tires. Fuel economy would have been a little better if they were all at correct pressure.
I'm looking to get one
You got to think about the diesel that's in the fuel lines. We just add more to it
It would be interesting to know if the truck went into regeneration mode during that loop as well. That will always hurt your fuel economy.
yes
it wouoldve dropped to about 11 lol, i have a 2021 that if i averaged 35 mph would be getting about 25 mpg, mine also gas 91,340 miles
Chevy/ GM pickups are really upping their game..
Bro how did you get the truck so early ? I been wanting to buy one
I believe why the trucks trip gauge was higher than your calculations was because of the prior miles traveled in the vehicle being at a higher efficiency.
Didnt he reset the trip computer?
He reset the trip computer.
I want to buy the LTZ midnight with leds all the way around, full size arm rest an duramax.
My 2020 duramax gets 25.1 mpg and it's great. While pulling my 24ft cargo trailer loaded it gets 15.3. I'm very happy with it. The gas version gets 12 at best not pulling.
1500 or 2500HD 4x4 crew cab?
@Chuck Neil Yes sorry. Crew cab long bed 4x4. Stock size wheels.
Gas will get 6-8 pulling…..10 at best
@299charles That's terrible. My 2005 Silverado crew cab gasser does better. Not a lot better but considering the age difference you would think technology today would be a major improvement.
I get the same in my 2005 2500
I had a 2001 Dodge Ram 2500 4x4 diesel, I was getting 19.6mpg and I drove fast, near speed limit I could get 22.4. New diesels have so many computers and emissions stuff on them. Getting near 19 is very good
The 2001 ram also made about half the power of the new diesels, so the new diesels are drastically more efficient at making power.
@@alexanderblackburn4520 you would think in 20 years you would be able to get better mpg
@@charlieb308 the 3 liters that have nearly comparable power, get way better economy. These tests are also at a higher altitude, which I am sure you know negatively impacts efficiency and performance.
Even with emissions intact - the 2024 doubles the power & doubles the towing ability of 2001 Ram.
I’d say that’s a huge advance….
This truck is still not broken in yet too. Sure it will get better in time and sure that high altitude they are at in CO effects it as well besides all the new emissions stuff
I'm imagining a world where the trucks didn't go back to 1970's sizes and utilized modern technology to get 30 mpg... a man can dream
I get 25.6 on long runs around 8-12 in town
Can you do some reviews on the new gas with the 10 speed?
Yes. This is coming soon.
There is a guy out there already doing tests with one. He concluded it doesn’t get any better mileage than the 6spd and also the final drive is about the same so that makes sense. He said 0-60 is actually a tad slower on the 10spd but it is quicker in passing acceleration.
@Barbells, Automobiles and Projects makes sense. We kinda hit diminishing returns once we hit 6 speeds. Because final drive is usually close to the same. Just more stepped gears to get there.
So ya as you said stomping it on the highway should be faster for passing power
Was your mirrors out?
Did you make sure the tires were at MAX P.S.I. Cold?
When pumped, Diesel fuel makes a lot of foam on top. You aren’t going to get an accurate volume measurement using a station pump. The only way to get anywhere near the actual mileage is on a full tank or use a glass container, etc. Or just use the trucks computed numbers.
Not too shabby.
The IFS makes them far more comfortable of a ride than ram or Ford. Solid axle better for off road, but IFS def better for on road comfort.
Sounds good to me. My dad’s 2001 Chevy S10 with a 4.3 (I think) gets about that same mileage (I think).
I do like the truck, but I will say that I got better with the Ram 2500, even though it is not apples to apples. Very good outcome, I think.
Everyone is still wanting to see the high output powerstroke doing super Ike!
It would make this video more meaningful if you would say how this truck MPG compared with your tests on earlier duramax trucks.
You who know so much about trucks, which engine do you consider best between power stroke, cumin, and duramaz, which is better for heavy work
Don't forget to add the cost of def to your total cost
Maybe calculate the amount of DEF used with the diesel vehicles.
I just got a 2024 rst 3.0 diesel getting average 28-32 hwy
It would do better if it was the same color as you Trail Boss Colorado. 18 not bad for a real big truck. 3.42 gears. It gets the same mileage as my 2001 Chevy S10 extended cab 2wd 4.3 auto w/ 3.08 gear, but gas.
My old 2003 Silverado duramax got 22.4 mpg with 3 people and gear for a week going from Wisconsin yo Yellowstone and back. Sounds like its the same to a little worse now.
The gasoline mpg to equal diesel fuel cost per mile (excluding dpf) is 14 mpg. Diesel may make sense if towing a lot, but it would take a lot to make up for the increased purchase price.
diesel in california is cheaper then gas
@@guamazolopez6456 and in most states again
You also have massively more reliable engines and better mpg
My 2005 lly gets 22 on the highway with 5 speed. Just saying
Same here, mine gets about 20 on the highway with an automatic transmission and I’m running 33’s
This big rig gets almost the same mpg as your new Colorado Andre….
Only difference is the fuel in the big rig cost more, I think people overlook that pretty often
