Based on interactions with others, I'd say most of us have moved to 5W40. Iv'e not been able to source Mobile 1 5W40 since moving to Texas, I've not used any Mobile 1 product since moving here OTHER than in the manual transmission and differential.


Details about just what oils are recommended and why can be found by an internet search for "MB 229.3" and "MB 229.5".
