I use MMO in the oil,,no damaged engine yet,,no smoking, no oil usage, no rattles,,ancient 318 engine,,2002
Dodge,,go figure. getting close to 280k miles on engine now.Will run this engine till she drops. I have quit splitting hairs over oils and such. I have lots of expediter friends that have no clue whats in their engines, they just go to wally world or a fast lube place and go on and some of them are at the 100k, 200k, and yes 600k miles on their engines and they aren't having any problems. we in BITOG may be in the minority on oil education, I think that 90 percent of the public don't care about their oil, just so long as the engine runs and momma can get the kids at school and go to grocery store and back, IMHO...
