After 14 years racing we had a camshaft failure after only 5 nights Isky .490 lift hyd stock rockers. The manufacturer told me that our friends over at the EPA changed the law so all engine oil refined after 12/03 for highway use no longer has ZDDP (zinc) for extreme pressure lube. And this is probably why we had the failure. I use Kendall GT-1 and this is why the color changed last year. Their recomendations. Use roller rockers for break in, add 2 cans of General Motors EOS assembly lube for break in and 1/2 can per oil change with the Kendall. I have only found 2 oil with this still in it. Penzoil GTP racing oil, and Valvoline Racing oil but I don't know how much ZDDP it contains. I may be behind the times on this but first I have heard of it.

I use Valvoline 50. Talked to an owner of an Pennzoil oil change shop and he wouldn't use any Pennzoil of any type in a racecar. He would use Valvoline, too.

Like the age old saying..."oil is oil unless its Pennzoil". I wouldnt use that oil in my car no matter what kind of car it is. JMO.
