2017 Ram 2500 6.4L Big Horn with 6'4" bed, full truck cap, 4x4

I am looking at options I can implement to help improve fuel economy. For the most part I seem to get 15-16mpg on the highway (on some pure highway trips I have managed as high as 18mpg) and about 13mpg when running local.

I run 89 octane fuel exclusively. I found with 87 the mileage was significantly lower. The cost difference in fuel price was negated by the increased mileage.

 

That's likely as good as it's going to get. With the VVT, and MDS, it just ain't gonna get much better on a truck pushing close to 6000 pounds.....

 

I agree. Those are pretty good numbers. I wouldn't complain at all.

 

Not complaining at what I was getting. Was just wondering if anyone had found a way to get a little more out of it.

Interestingly, my 2009 got better with age. When we first got it, the typical highway run was 16mpg. Now, 9 years and 220,000 miles later, it can easily get 19mpg on open highway, sometimes as high as 21mpg.

Can't wait to see what an 8,500lb / 32ft camper trailer does to the 2017 later this year. I think there will be a lot of fuel stops.

Thanks everyone.
