Rated 5 out of 5 by extraterritoriality A valuable add-on to each oil change!!
Of the various oil-change "pick-me-ups" available in the automotive market, this is the one I always remember to put on the list when I'm doing 3000 mile interval oil changes. It helps keep the compression up!!

by parlaypaul Best engine restorer product period!!!!!
I have owned 4 cars in my life and used Engine Restorer in all of them. 2 of them went 300K + miles , 1 of them went over 400K miles and the other is still going at 465K + miles. I think that this the best product on the market today!!
