Improve gas mileage 1997 tahoe?
realistically, up to date tune up, consistent tire pressure, premium good quality fuel.
If your getting between 14 to 18 that's about as good as it gets, I have heard that a re-programmer helps but not too much, around a mile or 2 per gallon.
Proper tire pressure and a tune up if it has over 100,000 miles. Uh, premium fuel will do nothing but make your wallet lighter.
