Here's some more info I found that refers to molybendum...it's from a test Amsoil had done to pit their product vs. Royal Purple...

Here's another good read, kinda elementary in some areas, but very informative:

i went to pep-boys on northpark and they tried charging me 50$ for 6 qts of royal purple 10w30. i laughed and went to walmart and picked up 6 qts of mb1 for 25 bux.

 

i'll still have to stick with mobil 1 walmart is the best place to get it!

 

Costco And Sam's Club Also Has It For Cheap!! M1 That Is.

 

****** government.

 

Well I guess I missed this thread but yeah. Damn Gov.!!!

 

fuggin govnt!!! guess i'll go back to castrol....

 

i use chevron synthetic!!! thats what we have at the dealer

 

Maybe Im mistaken, but once the rings actually seat, youll be fine..correct?..thats why its not recommended to use synthetic on a new build, so the rings will seat. Is this false info or true?..I figured is the Mobil 1 info is true like you say, if your rings are seated and you have been using synthetic for a while, it shouldnt effect your rings. or am i jus talking out of my *** again?..ha

 

I ran reg. Penzoil 5w30 in my truck for the first 9k miles. I just changed over last weekend to synthetic. I went with the Penzoil Synthetic since I've always had good luck with Penzoil. I figured I'd try it out for the first Synthetic Cycle. How often are you guys changing your Syn.Motor Oil?
