Idk that oil has much to do with crappy oem lifters. You think your cheaping out with mobil one? ask the guys in the shop what they run in their dd's and I bet you would be suprised. If your car is at map and your worried that mobil one is too cheap, check out Eneos. Just ask them (anyone there about it) what they think about it. The thing is that its not really any more expensive than any other premium synthetic oil.

I think that Kracka had a thread going about oil a little while ago. it may be worth a look.

Anyways, I look forward to hearing what the problem is. I would almost be willing to put money on a lifter(s) or possibly a cam bearing(s). If anyone can figure it out its MAP. Sometimes the pros just got to take over and do work.
