TFL runs on Sinclair fuel and so should you. Download the Sinclair DINOPAY app and start saving as much as $0.10 or more per gallon on your next fill-up. ( www.sinclairoil.com/customers )

2.5 mpg better is not enough better to justify a diesel in my opinion. The added cost of diesel fuel, oil changes that are triple, fuel filter maintenance, DPF filter cost, issues and maintenance. Way easier to just spend less for a little more fuel imo. Great videos!

I have had diesels since 1996 from all 3 manufactures. I switched to a 2020 gas F250 7.3. I still tow the same bobcats and boats that are 13-17k pounds. There are always compromises but the mileage is not that much worse and gas is less money than diesel. Where I really make out is repairs and maintenance. I am shocked at the 19mpg on the GM gasses and when the time comes I will drive all 3 and choose at that point. Andre, thanks for the review.
-
Just to be clear, the 6.6l gas is NOT an OHC engine, it’s a cam in block, OHV engine. I know that’s what Andre meant.
-
Went gas starting 2017 in my f250s, couldn't be happier. You don't realise how many little things you're always worried about with the diesel. No more extreme cold weather worries for starters.
-
As a 15 year diesel mechanic. For my money, what I tow, and seeing the repair bills on diesel pickups I'll stay with my gas HD truck. Will just have to see how the 10 speed gets along after some miles and real world use.
-
Best thing! No cylinder deactivation
-
The Bandit should be the engine name, because the Transam driven by Burt Reynolds was a 6.6 V8.
-
Switching from a modern diesel to a gasser eliminated all the stress on my long overland trips. Being stranded in the middle of the countryside is scary. No more check engine light anxiety :).

I purchased a new 2024 2500 HD LT, 6.6L gas about 2 weeks ago. Nicely optioned, just under $62k. To be used on occasion to tow a 7k GTW utility trailer. Watched this video with keen interest. So far the gas engine has been more than adequately powerful, and the Allison 10 speed AT impresses me,

I've had diesels for years, but after the DPF plugged up on my 2019 powerstroke ,my next truck will probably be a GMC gas. I pull a trailer with my bobcat once a week, but most of the time it's just a service bed with tools. My dad had five brand new trucks. They were all gasers,i still have his last one after he passed
-
was in market for a tow rig to pull 24ft enclosed trailer converted to toy hauler weighing 8500-9500 lbs. joined all 3 manufacturers numerous facebook pages and forums. after a month I decided to look at gassers. So glad I did! Diesel groups are all about limp mode, fuel pump, injectors, def heaters ect on and on. the gasser pages were all about what wheels, running boards, lifts ect. only pulling some weekend trips, it was a no brainer
-
Yes the diesel tows better. Yes it gets a little better mpg. But! It also has def, it also has dpf, if your fuel system fails you are looking at around 10,000 dollars to replace it. Not to mention turbo issues. I don’t tow very often but like the size and payload of a hd truck. I recently bought a 2024 gmc 2500 and couldn’t be happier. Just my take. 👍🏻

My 2021 2500HD 6.6L8T with the 6spd does amazing for fuel economy both empty and loaded here in Quebec, where most of the highways are far from flat! I normally average 12l/100km or 19.6mpg when empty and around 23l/100km or 10.2 mpg pulling my 9000lbs 5th wheel, speeds are between 100km/h to 115km/h or between 62mph and 70mph. Overall I am extremely pleased with my 6spd! I road tested the 10spd and found the torque management to really be holding the truck back!
-
I used to own a 8.1 Chevy and got 5 towing my fifth wheel and never got over 10 empty even on the highway due to the Allison which I loved they have come a long way
-
As a career mechanic my opinion is that the lower fuel economy of the gas engines far outweighs the mainteance costs of a diesel. Just installed a FCIM on a Duramax yesterday, $2000 box of relays to control the fuel injectors, and they fail often. Add in the cost of exhaust after treatment and it's just not worth it.
-
My work just picked up the plain Jane version of this truck, including standard cab. Biggest accessory was setup for snow plow, sticker is $53.5. Will be headed to NE as a shop truck.
-
This is how you start your day off great, with TFL & Andrea testing HD trucks. In my opinion I believe gaser is the way to go because the much higher upfront cost of a diesel over gas & then much higher maintenance on the diesel, and the diesel is only getting 2 & 1/2 mpg better??
-
No def, no worries about diesel fuel quality / additives, no $$$ after-treatment systems, cold starts etc etc etc. I will take it. Unless you tow a lot the gasser is he way to go.

I have a 2022 silverado HD with the 6.6l V8 and 6 speed transmission. Towed a 16' dump trailer that weighed 13,000 loaded. Hardly felt it on the hitch. Truck towed it great! Fuel milage was about 12mpg on 3 trips to the scrap yard.
