QUOTE=james schaechter;269482]I used to run Moblil 1 in everything and was evein running the 0 w 20. I had a problem a couple of times with rocker balls galling so I switched to the gibbs stuff and I have not had a problem with no other changes.
That was a few years ago. I hear that the Mobil one was still very good for street engines, but they kept making it cheaper and I am certain the zddp reduction is part of it.
Anyway, I looked at my total spend on oil each year and decided it was better to stick with something that worked for me even if it is more $$$. That was a few years ago. I am pretty happy with the decision.
Doesn't mean it won't work for you, in my case, it was a problem with stock rockers and the oil pump set up I run.

Sorry, I should have clarified for you Blue Oval. My reference about Mobil 1 being made cheaper was not a response to your link at all. It was a comment made to me from a friend who is an oil engineer and not a racer. I asked him about Mobil one several years ago. ( prior to the zddp thing too) He said that when Mobil 1 started pushing the higher volume sales through chains like Walmart, there was pressure to keep the cost down while maintaining the quality. He told me it was over engineered for it's application, so there was no real down side for street use at the time. I just figured it was finally pushing it for my application. Results will vary. LOL.
