Chevy diesel gas mileage

[mastercraftka]

Don't believe we're worried about fuel mileage. It was asked what fuel mileage do you get.

True and if you keep and eye on your fuel mileage it could signal issues sometimes!! It is smart to know what it is and what it is doing.

If I keep my '19 at 75 or under on the hwy, I will get 17-19mpg. if it is all "in town " driving say 30 mph or less it gets about 13-14. If I have a trailer hooked to it, it gets 9-11mpg.

2018 same thing.

I know diesel trucks aren't rated for gas mileage, but I was wondering what everyone else is getting. I have the 2015 chevy 2500HD 4dr, 4x4 and I get about 13mph average. When I pull my stock trailer or travel trailer I get 6mpg. This just doesn't seem right. I really thought that it goat about 18mpg average when I bought it. It has 92K miles on it. All regular maintenance done.

Ask BTB how them Ford PSD run on gas! Pretty sure chevy will be the same!

My old dodge 6.7 got 18 deleted on 34" tires....13 before delete.

16 4x4 crew 16.9 city and 18.5-20 depends on how I drive it. Haven't really pulled a heavy load other than my boat or low bow

I got that but if we weren't worried then why ask?I am not busting balls I just don't see what it really matters if you are spending 60 grand on a truck. That's all I am saying. This isn't the 1st conversation on here about fuel mileage. Buy the truck you want to drive and drive it

It did have some white smoke coming out of it this past week while hauling an empty stock trailer up a very tiny hill. Other than that I don't see any smoke, but I don't look either.

That is usually a sign of an injector issue.

AND BETTER GET IT TO DEALER ASAP!!! Before 100K miles
