Gas mileage increase w/ plug change
Gas mileage increase w/ plug change
When I installed my new injectors about 10k miles ago, I put in a new set of platinum plugs. I was running way way rich and after a decent tune i was getting around 16-17mpg. Well I just swapped out the plugs again with coppers two weeks ago, and now I just calculated 19mpg. Not too shabby.
