Switching from 10W30 oil to 0W40 - Mobil-1
 

I plan to make this switch during my next oil change but just want to get opinions/comments. I'm more interested in protection than flow - if that makes any sense at all!

I like it but mostly from a flow point since I drive my Z in the cold. It does have more zinc and phosphorus than some of the other Mobil 1 formulas which is good for wear protection. It's also supposed to have more PAO than some of the others but I don't have any proof of that. Below is a link to a recent oil analysis that I had done with the 0W40.

Thanks. Too bad the forum is so slow because there's some good info here!

Research on oils isn't limited to Z forums. :D Lots of info on this subject by going to that beloved website called Google. :023:
