How many MPG does the 2024 Silverado HD 6.6 Gas 10 Speed Allison get City and Highway driving?

PAYLOAD & TOWING SPECS FOR THIS EXACT TRUCK - see below
This truck has the standard 17" tires. The Load Index on the 17"s only allows the following weights.
GVWR: 10,450
GCWR: 24,500
CURB WEIGHT: 7,273
MAX PAYLOAD: 3,177
CONVENTIONAL TOWING: 14,500 LBS.
GOOSENECK: 16,970
If this truck was ordered with the 18" or 20" wheels, the GVWR would be 10,850 which would increase payload.
** ALSO ** trucks with 18" or 20" wheels have a GCWR of 26,000.
Unfortunately, I did not order this particular truck. Me, personally, if I order a truck for the lot...I go for maximum capabilities.

My first new car was a 72 Monte Carlo with a 402. We had some trouble with the valves and Chevy finally brought in an engineer from Seattle. We popped the hood and he said, "that's a truck engine." Loved my Monte Carlo and maybe it's time to get the truck that goes with the engine (even though they're not exactly the same). MPG was about 18 on the road, but I did get 20 MPG on I-95 once.

[@Back_door_bandit_98]

A engine isn’t magically going to get better MPG from just putting more miles on it.

[@andrewshoe6832]

​​@Dually Life 979 As engines wear in and tolerances loosen up a bit, there's a reduction in friction losses, leading to an MPG increase. Extremely common for this to happen across brands.

[@ttank1994]

It's true, I experienced the same thing. It's not just the engine, I think a lot of the friction comes from the differentials. New bearings get set with a good amount of preload, fresh differentials make more heat while they're breaking in.

[@dannyboyd1299]

Actually the do once they loosen up tolerances. Open up a new pair of pliers, keep it oiled and once it's broken in it will open and close easier ​@Back_door_bandit_98

Your math is wrong, you averaged 18.2 with the F150. 16mpg is about the best you will ever see with this truck and will average closer to 12mpg. There is no way you'll average 16mpg with these trucks, not bashing them, it is what it is. I have a 6.6 so I'm saying this based on real experience.

[@bradniehues9560]

Great video. My 23 6.6 gas gets about 14.5 in those same conditions so looks like about 1 mpg better with the 24. Figured it would bump a bit. I have a 24 on order hopefully it gets here by summer. I thought the refresh would be in 23 but it got delayed and I really wanted the 10 speed so that’s why I’m trading in. My 23 already has over 10K on it and I got it four months ago so I put a lot of miles on. Overall I’m happy with the 6 speed but it lacks a little mid range towing power from 3rd to 4th. The 10 speed will clean this up. I don’t tow a lot but when I do it’s heavy. Most of the time over 20K GCW. The 24 is rated up to 26K GCWR so that’s bump of 2K over the 23. I still have a 2015 GMC diesel that I’ll keep around but if this new gas/10 speed performs like I think it will I may not ever buy another new diesel unless I start to tow more often. That’s where the diesel shines IMO. Great content and thanks so much for sharing. Some of us have 24’s on order and have no idea how they will perform till we take delivery!

[@matthewanderson9912]

Nice video. Thanks for saying you don’t think the mileage will change much due to the very similar OD ratios. I’ve been saying the same thing ever since they announced the 10 speed for 2024 trucks. 5th and 6th have the same exact ratios as 8th and 9th (0.85:1 and 0.67:1) and 10th is just slightly taller at 0.63:1. I don’t personally think fuel mileage was the target here. I think drivability was, especially with towing. The 6L90 does an ok job but it needed another gear between 2nd (2.36:1) and 3rd (1.53:1). The 10 speed will give it two (3rd is 2.06:1 and 4th is 1.76:1). This alone will be a huge improvement for towing grades. Where I live in Kentucky and travel to go racing through Southwest Virginia into East Tennessee I have several steep grades including an 8% that crosses the mountain that serves as the border for Kentucky and Virginia. I’m very confident the 10 speed will be an almost daylight and dark difference in pulling that grade. Also the direct drive gear (7th gear 1:1 ratio) will I think eliminate the 4th to 5th gear hunting the 6L90 does when towing when you need to have a slight acceleration and/or have slight grade changes. The only downside I can see could potentially be grade shifting. The 6L90 does excel at that. The 10 speed with such close ratios may not do that as well.

[@lcee6592]

Unless I missed it, gotta love the guessing gauges. (oil, temp, volts) Only a number at each end and no numbers in between. Imagine a tire gauge that starts at 10 psi and then marked only at 100 psi. They really are not gauges without numbers.

Not pulling I think I'm getting around 14mpg around town driving and 15-16 on the highway, we mostly use this truck to pull our trailer. My math shows that I would only save about $500.00 a year on fuel if I went diesel based on the miles we drive so I'm pretty happy with it considering the hassle of new diesels.

[@JetTech1966]

I agree pryme. I was hoping at least they would put in say 410's in the rear and make 9th and 10th gears like super over drives to where the engine was running around 14 to 1500 rpm at say 70 for better gas mileage with intermediate towing ability. But they didn't...they just shoved more intermediate gears from start to cruise. I think someone missed the point of the 10 speed ability here, say like GM engineers. So basically there are more gears between start and cruise. But cruise still has basically the same ratio as the 6 speed. Makes no sense to me. I think they missed the mark on this one big time. Sure it might do better pulling at slower speeds. But who buys a gasser to tow all the damn time? I'm sure there are some out there that do, but I bet they are in the minority big time. Of course these are big trucks that weigh a lot, gas mileage is not really something on your mind when you buy one. But they had a chance to make it a more main stream truck that totally demolished the 6 speed. And I just don't see it. Why didn't GM give us 6 speed owners a huge bump somewhere to want to upgrade? Total fail in my opinion.

Great video, keep it up and thanks for the info!! Now just for curiosity sake, just for towing. Not interior cabin noise or ride or any of that, just towing. This or the old hd 8.1?? Not maxed out towing 30k, just a general 7k load or camper?? Which one does TGJ like better for towing ??

it's more fun with the 8.1

[@dguiley]

I had an ‘02 with the 8.1 and was disappointed. The only thing that made that truck better than my 6L was the 5 speed Allison over the 4L80

[@dommeister4004]

I’ve owned 5 8.1 trucks with zf6 and Allison combos. Bought a 2015 high country with the 6.2 and I’ve never desired owning another big block again. Truck pulled my 20ft car hauler with a z71 on it and got 12.2 where the 8.1 got 6.5mpg. The 6.2 would absolutely run circles around the 8100. Hearing really positive things on these 6.6 gas trucks

[@benschmitz554]

You should do a mpg test after the engine has a couple thousand miles first. In my experience with trucks they get better mpg after they have a chance to break in

[@truckguyjoe]

Agreed

16 mpg for a truck that weighs 7,500 lbs is incredible. I wonder what the mpg really is on the 6.6 diesel engine at 475 hp.

Have you found any difference in ride and hand,in between standard and Z71 equipped trucks? Basically it’s the Rancho shocks so do they make a difference?

[@truckguyjoe]

The Rancho is slightly stiffer. The average person probably wouldn’t catch the difference.

[@PatrickAllison-zz2gj]

I had a 22 and they said it had way less electronics on the engine because of the chip shortage, I know it didn't have any cylinder deactivation or anything. It got 18 on the interstate,like the toll road in WV . In rolling hills it got 16 to 17 . It was the 6 speed. 16 was the worse it got. So the 10 speed did nothing.

[@truckguyjoe]

I think we’re only going to see a difference when pulling a trailer

[@woodysrockspyro6436]

My 2023 with the 6 speed is sitting at 12.1 overall for 11,000 miles. Only pulled a couple big trailers.. it was getting 6 to 8 pulling them. Empty it averages a little over 13. In the ozark hills of Missouri

[@dufus2273]

It made GM richer. More expensive to repair. they make more again.

[@JS-ft3np]

Just picked up one of these last week. So far I’ve been getting 13.4 combined but it only has 100 miles on it. Going to pick up my camper from warranty work this week hopefully. It’s a 3250bh by grand design. All in last time I weighed it was at 11210lbs. Hoping this 10 speed behind the gasser pulls pretty good. Have you hooked yours up to anything yet?

[@79xlch]

My 24 , 2500 pulls gooseneck with skid steer fine. 15,000 pounds. Transmission never went past 7th speed. All round average 14.5 with 500 miles

[@JS-ft3np]

Finally got the camper picked up. Truck does surprisingly well with it! Coming out of a 19 2500 duramax, I am pleasantly surprised how well it pulls the camper. My mileage is starting to get better as well, 13.5 combined for the most part. Question for ya, my tranny when not under a load seems to hold first a little long sometimes. I can feather the gas and it just seems the rpm’s wanna get to 2500-3k rpm before it shifts to 2nd and it’s driving me nuts. I can see if I’m on the throttle the Roma being like that but it’s like the truck just wants to hammer all the time. Have you seen this with yours, curious if you can do a shifting video just featuring the throttle to see if it’s just mine or not…

[@petebusch9069]

I'm pulling an ATC2816 toy hauler that weighs around 10k and it pulls it very good in my opinion cruising around 70mph. I get between 6-8 mpgs driving around 70mph pulling the trailer. Its not much but is still WAY more cost effective than a diesel. Overall I'm very happy with the way it pulls, the 10 speed works very well, my tranny temp never gets over 175. The motor is strong but will work on steep hills meaning you either slow down a bit or put the hammer down to hold speed. If your always in the mountains then you may want more, that seems to be the limit.

[@chrisrichardson8908]

So if I’m understanding this correctly. You would have to derate the 16k trailer to 14k to legally pull it. Otherwise you would have to move upto larger tires to pull a 16k trailer

[@truckguyjoe]

Before I answer… I need to verify the GVWR on the trucks with the larger tires… As long as the GVWR does not change, that is correct. The small tire trucks have a GCWR of 24,500… Versus 26,000 for the trucks with 18 or 20s.

I just put a deposit down at a local, Rapid City, SD dealer, to get in line for an allocation, for the "privilege" of paying MSRP +Dest. for a 2024 3500HD LT long bed dually w/ 6.6 gas. Will be pulling my 16.5k lb 5th-wheel camper.

[@truckguyjoe]

MSRP will become the norm more and more...GM has increased the invoice cost to dealers. I have seen the markups shrink considerably on new units...you don't have to believe me or take my word for it...but I can tell you there is $0 profit in the new Silverado EV. Line 310 on the invoice is the same as MSRP with destination.

[@screddot7074]

GMC gives you the new front end on all levels including work truck. Don't know why Chevy wants to jerk people around. I'd have to go to the LTZ to get the options I want with Chevy, but only the SLE on GMC and at least $10,000 less.

[@Featherburner]

@@screddot7074 That's strange, to get the options I wanted in an LTZ I'd have to step up to an ATX4 in the GMC and pay an extra $5,500. Or I could have settled for a less optioned SLT and only paid $3,000 more for fewer options!

[@guesswho9742]

You would think after over a hundred years of porduction and tons of resurch and development, a $60k new truck would get better mpg than my 1999 GMC Yukon with 220000 on the clock?

[@mattwag11]

The HD weighs substantially more, about 1500-2000 lbs more probably closer to 2k. That's a lot of extra weight hence the mileage difference. Now put 2k in your Yukon and see what mileage you get and that's a more accurate comparison. My 19 2500 High Country srw crew cab weighed 8300 lbs with me in it and a full tank of fuel and I'm only bout 175.

[@chrisrossman9566]

Wow, that thing weights 7500#s empty. and gets that good of mileage. A GMT800 2500 with the 6.0L is less than 6,000# and got less than 12mpg.

[@toushhog]

What are the gear ratio options for the gas with the 10 speed? Still 3.73 only option?

[@truckguyjoe]

Correct 3.73. There is going to be a max trailering package available for the gas & diesel. I will research to see if there is a lower axle ratio for the package.

[@toushhog]

It will interesting to see if they will offer a 4.10 or so for the gas. 4.10 and the 10 speed will be a great combo to replace a diesel.

[@jeffmercier7252]

The rear axle ratio will affect your MPG no matter which transmission you use

[@truckguyjoe]

I agree… Hopefully I didn’t accidentally say otherwise. No matter how many gears in the transmission… The lower the rear axle ratio, the lower the highway mileage. As you are aware… Most people confuse the difference between a low gear and a high gear. 4.88 is much lower ratio vs a 3.73

10th gear being so tall I don’t know how it would ever be in that gear except for when unloaded on flat/decline road. Towing heavy seems to be the only advantage so far as real world MPG feedback is no better than the 6 speed.

Agree… Basically keeping the truck in the correct rpm range when accelerating with a load is the main benefit.
