I am trying to do just about anything to improve gas mileage. I have a 1992 351w automatic and pushbutton 4x4 with auto hubs. The truck has 113k miles and I like it. Here are some of my ideas. I am trying to get close as I can to 15 mpg on the highway. The tires are New 31x10.5r15 brigestone revo II

1. K & N air filter -done
2. manual hubs
3. possible desmog

If you have any idea's please let me know. Thanks
