what oil to use

Lots of good info Ace. A lot of it jives with what I have read. The part about ZDDP concentrations over 1400 was one. The numbers I saw were not to exceed 1500 by much because of the ash issue. I don't know about what they say about just going ahead and using the 800ppm stuff though. as I said earlier, the thing that got me started on this was several posts on various racing forums from muscle cars, to Buick turbos, to Jap cars about guys losing cams and not knowing why until they found out about this issue. When they went to higher ZDDP oils the problem disappeared. I think I will err on the side of safety. I also noted the Pennsylvania crude stuff. That is the whole selling point behind Kendall/Brad Penn green racing oil. It is supposedly so much better because it is Pennsylvania crude.
