The EPA Doesn't Want You to Know the MPG of the 2024 Chevy Silverado HD Duramax - Let's Find Out!

Have we not reached the summit yet? Can manufacturers finally stop worrying about having the highest, most obscene power numbers and instead focus on reliability? If you’re going to charge me 90k for a truck, can it at least last the majority of my lifetime?

I love that you guys team up every Saturday here lately!

2004 GMC Sierra 2500HD, Duramax LB7, Allison Series 1000 5 speed, no EGR, no DEF, no regen. 522,000 miles, 19 MPG daily driver. Mine. What else can I say? Oh, it runs like a dream.

Banks, as in Banks turbo, have a great video where they dismantled a 2023 & 2024 6.6 DuraMax and compared them. You want the 2024 vs prior models. Especially if you are looking at a brand new 23 vs brand new 24 truck. There’s a lot of High Country (2500s especially) sitting on the lots so if you are in the market for a High Country, you have great choices. I would get a 2024!! I much prefer the 1 ton or 3500 HD trucks so this should be a great video and baseline.

Great info. With more miles on the truck, fuel mileage should get better. My 2017 Ram Dually mega cab 4x4 diesel just crossed 50,000 miles. Recent trip towing 20' trailer , tractor with Backhoe attachment and loader, box blade and Brush hog (11,000 lbs @) I averaged 14.5 mpg running 65 mpg max. Roads ranged from flat to very hilly. 350-mile trip.

It's not that "the EPA doesn't want you to know" the mpg, it's that heavy duty trucks are exempt from having to report it. Big difference.

@Automatic inquiries already did this run and the Silverado did a good job. He went over 160 miles and showed real world numbers over the IKE.

You also need to do this identical test with the gasoline versions as well. This would showcase the difference in fuel economy between the gas and diesel options in these trucks.

Great report and video! Very good to see real life numbers versus showroom salesmanship!

I will stick with my diesel, 2003 F250 7.3 powerstroke19 years, 335,000 miles and counting with no end in sight. No engine failures or major issues, gas just doesn't get there.

I bought the 2022 Duramax AT4 3500. Let's just say the first thing that I did was drop the 36-gallon tank and installed the Titan 54 gallon tank. To be fair, I pull a 42 foot fifth wheel.

Mr Truck the gooseneck ball just behind the rear axle gives a better ride and leaves more room for a bigger tool box or aux fuel tank in the bed. I know at least one ford 350 guy that moved the hitch back just behind the axle for towing his 5th wheel camper and it helped the ride. Good to see you guys doing these again. Always enjoy Mr. Truck and Andre testing trucks I no longer have a need for but I am still interested in. Hope you guys stay safe and healthy.

People comment on the expense of these trucks. You either need one or you don’t. If you do, then the cost shouldn’t be a deterrent - if it is, whatever you are doing that you need a HD truck for , you aren’t charging enough. If you can’t write the check for it then it probably isn’t for you. It’s a business expense , and if it’s used as so , your business should be generating enough cash to use the write off and make the purchase. If not , stick with a old beater , or take a job working for a company where you can drive a Toyota to work

I would love to see an MPG loop of a 'similar' diesel pickup from the 90's or 2000's before the EPA slapped all the emissions junk on them. Maybe something like a 2000's LLY or LBZ.

Show us the 2024 6.6 gas version of 100 miler, and the Ike in a 2024 GM gasser. I would also like to see a practical tow test, you always max out the ratings. Most of us (in the west) buy trucks with the trailer in mind, and try to stay at 70-85% of the tow rating. Compare half tons with the typical camping load (7-9000), and 3/4 tons with 10000-13000.

My 2006 LBZ Duramax gets 12.5 towing 10,000. Y’all have fun spending $90,000 for fancy buttons and screens. The trucks aren’t all that much more capable than 17 years ago. It’s just a bunch of flash.

Mr. Truck it's always great to see you and get your comments on these new trucks so keep it up and TFL keep having Mr. Truck on you channel as a special quest !

These Saturday morning videos are making a LOT of people happy! What a great way to start the day.

Mr Truck and Andre make the best videos. 👍🏻👍🏻

But I LOVE where they put the 5th wheel..... because now I can pull my gooseneck with the short bed and not hit the cab of my truck! Come on Mr truck.... That was brilliant, not bad...... It tows great. At least on my 5th wheel which is 14,500. Course I'm using the gas truck too which pulls amazing. No more diesel for me.... Thanks EPA
