Any of you use it, does it have enough zinc/phosphorus for our flat tappet motors?
 
What makes you say that?

When we raced jrs it was the in thing, guys ran the light oil and thought they were doing themselves a favour. I have had the good fortune of working on a super stocker and he has tested many oils . I think the Brad Penn and Valvoline VR-1 are way better oils. Do a search on this, Nick Micale has some good advice also.
 
Not trying to beat a dead horse with the same old question, specifically refering to the hps formula wich I didn't know they made till today .. they say its not for use in cars under warranty cuz of the added zinc phosphorous..I've read more than I care to admit about peoples opinions on oil, trying to find out if the rp hps has levels of zinc etc that is safe for our motors
