this is my first diesel truck so far, its a 2000 2500 extended cab 4x4 with 60,000 on it. I was a little disappointed at the 16 mpg with the first tank of fuel. any suggestions of improvements? and the truck is bone stock, 57 year old man had it he bought it new!!!

 

Welcome to the forum. Buy a programmer and unlock up to 80hp and 100tq.

 

I'm not sure if that'll help his mpg or not, but definately a cool thing to do. Oh, and welcome!
