What Oil to use?M1, Castro synt? or other

[Jake Raby]

The engine's oil DOES NOT lube the IMS bearing in factory form. The factory IMS bearing is a permanently lubricated SEALED unit... Thats why it fails. engine oil selections have little impact on the IMS bearing.

sorry, I did it again. It was the AOS they were talking about. Thanks for heads up on my mistake, I will edit it.

Hey, wait a minute, you are the guy I have been googleing for the past two days.

Sorry I am real slow today(slower than usual). Please put this to rest, as you have more knowledge in your little toe Than I will ever have on this oil issue. What do you (or can you legally) recommend me to use in my 2001 boxster "s"? Please include weight also(I live in ohio but don't drive too much in winter). I plan to change every 7000miles or once a year. MY car has 60k miles on it, I don't abuse it, but I do like to hear it sing through the gears quite often.

Ps do you still think ZDDPlus is a good additive for me?
