Can someone comment on the 6 L gas engine from GMC and Dodge when you get into the 2500 3/4 ton series truck? Thanks.

6 Liter Gas

I have the Chevy 6 liter gas, 2012 model. I chose the gas version because I just don't tow enough now, to justify the additional costs to purchase the diesel, and maintain it. They are ten grand more, but that's not the ? you asked.

I wanted the GMC as I had a 2500 Yukon XL previously. When I needed a truck, there simply weren't that many gas GMC 2500's on the market. I found this Chevy in NJ, it was certified pre-owned with only 9k miles on it. I saved a bunch, and got the full factory warranty.

Pros: Sits 2" higher than a 1500. Brakes are massive, and boy do they stop this truck. 6 Liter is a proven block, with parts readily available even in the boonies. 300 HP's under the hood. When you need 'em, they are there. 36 1/2 gallon fuel tank. A long way before your next fillup. Frame is huge, and lots of room under the hood. Tows almost anything I can throw at it with ease. Roomy cab. I got the rear DVD, and whoever is in the back can watch a movie, while I listen to XM.
Ride is smooth as silk when towing, and rides better with a load.

Cons: Can be tough to park, even when I chose the 6 1/2 foot bed. I couldn't imagine the 8' bed. A little stiff w/o a load. Don't like the electronics as they were outdated before they even built the vehicle. Leather seats are only partially leather. No bluetooth. Options are WAY overpriced if you buy new. Even tho I have the 3.73 rear end, I feel I should get better gas mileage. No inside handle grips directly above your shoulder. Only at the 2 o'clock mark when seated. Good for entry, worthless for riding. Far too stripped of a vehicle for what you pay. I have SO many upgrades in mine. From window tinting, rear under-seat storage, bed liner & a rubber mat, LED's. For what GMC charges, you should be getting MANY more options on the vehicle.

New, these damn things are now over 50k. With the GMC's in the 60k $ range.
Ridiculous. It's GMC's cash cow, along with their Yukon XL & Denali. Too bad they KNOW this. Sorry, I am a working man paying for three children's college edumacation. My wallet is only so deep. Yes, I am happy with my truck, but I don't like the price I had to pay. If you go with the 2500, make sure you get the 3.73 rear end. The new Cheby's have the 6 speed tranny. My old Yukon did not. If I went much over 65mph in the Yukon, the fuel consumption wasn't worth the 2 extra minutes to get there. Definitely buy used, and preferably re-certified Let someone else take the HUGE hit when THEY drove it off the lot, not you. It does the towing job very well. If you get hit in it, with the size of the frame, THEY are gonna be hurting, not you. I do like the safety factor of the larger & heavier vehicle. My family's safety is worth the extra fuel I pay to own it. It's a beast, but that's what you bhought it for, is to do beastly things. And it does those very well IMHO. Good luck, stay safe, and enjoy the ADVENTURE of owning your AS.

That means fuel consumption is much less than gassers. About 70% of a gasser. Besides diesel engines are built more for long heavy duty service. Maybe an engine life of 300,000 miles. Some of the Ford diesels engines have not done as well in the past. Hopefully, that is now corrected. I think GM has the best engine/running gear/body track record to date. Dodge has a great diesel, but the running gear/body record is wanting.
I'm not saying that there's no support for this, but several items here are significantly overstated.

First off, low-sulfur diesel has about 13% more energy per gallon than gasoline. This is still a real difference but nowhere near 50%. Biodiesel has less chemical energy per volume than ULSD but still a bit more than gasoline, so blends of biodiesel and ULSD will be in the middle.

The "turbo" in turbodiesel is what maintains much of a turbodiesel's sea-level performance at altitude. A turbocharged gasoline engine provides similar benefits at altitude and a direct-injected turbocharged gasoline engine also produces significant low-RPM torque. (Yes I'm aware that turbo DI gasoline is more of a half-ton option, I'm just pointing out that the high-altitude magic comes from the forced induction, not the fuel.)

For fuel consumption, the diesel crowd had a bit of a flat spot as tighter emissions controls were implemented. It seems that the newest models have recovered a lot of the fuel economy that went missing for a few model years, but if you're looking for a lightly-used truck you should see what people have been getting with that model and year in the real world before you bet on getting high towing MPG. It may be worth it to spend a bit more on a newer vehicle, or buy one a year or two OLDER than you would choose otherwise if MPG is a primary consideration.
