WalMart still does not carry 5W-30EP in 5 qt containers. Has anyone seen this around yet?
The Iron in your engine is probably rejoicing.
Someone correct me if I'm wrong, but I think the "elevated iron" that has been observed is limited to the M1 regular line, and 5w30 in particular.
Anecdotally, my mothers' Taurus did a full 1yr close to 10k mile on M1 EP 10w30 - iron was 9ppm. To quote M.C. Hammer - "you can't touch this". Or in legally correct oil company marketing - "you can't surpass this".
