High-zinc oil or ZDDP oil additives?

Just regular VR1 valvoline, easy to find and has a lot of zinc etc.. So you don't have to play chemist.

This ! and if your engine is sealed and finely tuned like mine, the vr1 will be clean at the next oil change. I have used Valvoline exclusively for 40 years, with no failure at high rpm racing and street use.
