i cant agree, with any of them. Alot of the bad stories, are from user error. That an injector might get clogged from the cleaning, or like me you might actually use a vaccum line that dumps the stuff into 1 cylinder, and floods it. But If you use it how your supposed to...it works fine.. my escort has 227k on it, and no harm no foil, my protege had 130k, and no foul.. my svt had 110k, no foul, moms pt cruiser has 160k no issues...
