Default Re: Motor oil info

Joe I asked a local excellent engine builder that question to day...he shrugged his shoulders...there are no additives that are really worth a damn ...He actually rarely builds a flat tappet motor anymore. All rollers for the most part. It's important to know that it is mosy critical on break in though. Rollers are unaffected but I think we may need zinc in these old engines....are there any engine builders on this board that can shed some light ? I know the racing oild have some zinc in it still and also Rotella oddly enough.

Don't mess with old farts - age and treachery will always overcome youth and skill! Bullshit and brilliance only come with age and experience.
