I believe a Ram 2500 is a bit heavier than most of us here who have 1500s though, BlueBeast, so you may get a little worse mileage than the rest of us.

 

Didn't really pay attention to the fact everybody had 1500's but me

 

i get around 11mpg average. your driving habits will net you the best mpg's. but donnt look to get much better. you are getting pretty much the standard. and when people say they get 18mpg i just laugh and think, yeh, right. heck the new hemi's with mds are barely getting that. and some donnt.

 

I used to get around 14 until I put more aggressive all-terrain tires and had the pcm reflashed to where the torque converter doesn't lock up at all in third and then doesn't lock up in fourth until 52mph. Now I am getting around 12.5mpg.

I also put a timing chain tensioner in a while back, would this hurt my mpg's?

 

I used to get 40mpg city and 55 on the highway.
but now that I got a Thottle body spacer, tornado, and switched to Slick50, I get 50 city and 70 on the highway.

 

he,he.

 

laugh if you must about us who get 18mpg highway... but when you achieve this level of awesomenitiy while driving, you too will understand the way of the road---true story

Ancient Chinese Proverb-

 

I get 18mpg at 55 mph but as soon as i get over 55 it starts going back downhill. Only about 10mpg in the city though thats with 265/75/16 Firestone Destination M/Ts

 

next you need to get a ebay chip, and a hair dryer trubo,, then you would get 65 city and 85 hwy,, and have 500hp.....

 

those are on my xmas list!

hope santa has a paypal account.
