STP Oil Treatment
My 327 engine is a flat tappet and I know that the engine oil should contain zddp. Would one bottle of stp oil treatment have an adequate amount of zddp to provide the needed engine protection? I see I can purchase a bottle of ZDDP on Ebay for about $14 but that seems awful expensive. THanks.
