i don't see any issue with the power service stuff. IIRC gm officially recommends standadyne but power service is a good choice and more readily available. the marvel mystery oil is another story and i'm not sure how the injectors will like it.:spit: the cummins had mechanical injectors for several years and you can run darn near anything through them without hurting them. some even run filtered waste motor oil. i don't in my cummins and this is a big no-no for the duramax.
I run the same stuff occasionally even though our fuel at the farm is 60/40 blend.........Doesn't help my mpg at all never did when i had a cummins or dads stroker.I run the power service in the white bottle, its a cetane booster, cleaner and anti gel, dose it work? i dont know but i run it just for peice of mind aginst low sulfer diesel and now ULSD!
