    As the title states, is it safe to run that? Several people advised me to do this, as my lifters are tapping. Thanks!

    I'm running 10w40 full synthetic right now. Should I probably run 20w50 full synthetic? Or can I just switch back to conventional oil, 20w50?

    Go with 15w-40 truck oil. MMO and a kero flush is a help.

    I actually talked to a dealership. He advised against it, said he only runs that in diesel trucks. He said use half 20w50, half 10w40, and I added one qt MMO. It runs like a champ now! Very quiet. Went back to conventional though, and it helped.

    Stop talking to dealer "techs".

    Anyone who doesn't know 15w-40 is the best and most advanced formula, is pretty much just guessing.
