I have done a similar thread and got lots of good info back. Search "20 mpg hijak thread" and you can read all the good advise they gave me as well. I have had some improvements based on doing some of the recommendations, but I have limited funds and limited skills to have executed all that I have planned to do over time.

One thing that really helped me was a really good tune up. I know that one spark plug I replaced had to have come off the line with the truck.
