Ill tell you why from what I heard.

SF will losen up dirt and debre in crank case and could cause dirt to get into oil journals and next thing you know.

You need a new motor.

I would never put anything in crank case besides 5-30 Mobile 1

Just my 2

My car smoked for like 10 seconds with 99K miles. You must have a lot of miles, or something.

off topic but has anyone tried zmax yet??? Carroll Shelby endorses the stuff. Just wondering if anyone has tried it. They say that it soaks into the metal or something...which seems like total bs. But i dont know.

my buddy swears by this stuff....i dont think enough to buy it, but he says it works good....he steals boxes full of it from his job at a dealership that uses it in their cars...i doubt he would pay $50 for a bottle of it though, i know i wouldnt, and i cant actualyl believe anyone in their right mind would
