Any one use their oil? I understand they make oil for racing. What the hell is the difference between an oil made for racing or street?

Is suppose to be illegal if used for street cars? My buddy has a bunch of Total oil in his shop (He has a lift, thank goodness) that he uses or swears by, for his ratty old race car and was nice enough to offer the service (I was really hoping he would do it for me) but I get to help

(damn!). Is there enough ZDDP in Total oil. Those Brad Penn kinda sold me on their oil at Rennsport. I know, I am gullible and dumb.
