I read the article about oils & zip in the latest Austin Healey Magazine and now I’m a little confused(it doesn’t take much to confuse me) and I google Mobil 1 and Valvoline racing oil for street/track.
i had my camshaft regrouped by Elgin in 2012 andDema sentme a Mobil oil spec sheet with Mobil 1 15w-50 circled. ((I will scan and post later). It shows Phosphorus level at 1200 and Zinc at 1300.
tge sheet is dated 5/27/2010. i am posting Mobil and Valvoline spec sheets.
thoughts on oil today that we can buy?
