just wondering if anyone could tell me what i can do to improve the mileage im getting? the vehicle is a 1993 gmc sierra 1500 sle with a v8 5.7l engine with 2wd not 4x4 that has 240000kms on it. i know a tune up is due on it, but was wondering what else would work

Wasn't meant for gas mileage but some basics: Tire pressure to suggested pressure. Unload unnecessary stuff. If highway use just slow down some can help but there's no magic out there to make it do tons better. Good air filter can help too along with being in general good tune,

As Tom said , do the basics and common sense stuff, like accelerating easy anticipating stops, drive as smoothly as possible .You will be suprised how much it helps . Stay away from the gimicks , Fancy induction systems , super duper mufflers, chemical additives, a bottle of injector cleaner now and then is ok . Magnets on fuel lines , etc, The only gain will be the sellers profits.
