Looking to improve gas mileage on a '98 5.2L with around 96K miles. Besides the obvious, are there any little details that anyone knows of, or has had success with, that can improve the gas mileage on these suckers? Regarding the obvious as well, is there anything you've done that has greatly improved the mileage? Any and all tips/advice is welcome. Thanks!

 

greatly.... Thats tough, no such thing as great improvements. But with the proper mind of letting off the throttle power adders are also MPG improvements "If" you lay off the gas. Off my mind a few are, Intake/PCM/Exhaust/Electric Fan/T-Stat/Water wetter/and gears

 

The only item that I used that showed about a 10 percent increase in mpg is changing the paper air filter for a high flow filter such as K&N replacement.
