Bought a '84 chevy s10 blazer. Only has 48k original miles on it. I am getting average mpg, 17-18, but would like to get better. What are some easy and fairly inexpensive ($400 max) ways to improve?
Cold air induction filter. Electronic ignition. Free flow catalytic converter.
Something simple but often overlooked. Make sure your tires are properly inflated. You could even go a 1-2 psi over for less drag but a stiffer ride.
Supposedly running synthetic motor oil and changing the differential oil to synthetic oil is supposed to increase gas mileage a few percent here and there, but I've never experienced it. You're getting the EPA rated MPG in a 30 year old truck right now
Correct, I'm sure no matter what you do you won't get much better on that Blazer. Maybe 1-2 more.
