Thrashed, click on racing oils.. That's the one I was talking about. Blue bottle, not silver. Accordign to the EPA, any oil tagged SM cannot have the high zink. No exceptions. There are other additives that might do a similar job, but I dunno. The racing oils are not API rated.
AHA! Mine was in a silver bottle and SL rated. Dammit, that cost me alot of money and time.
