The Bel-ray oil in the above voa link has about 1500 ppm of this stuff. Whats it for and does it indicate a high quality oil?

Thanks for any help.

Friction modifier and antiwear,Hmmm... I wonder if its better in a wet clutch application than the other FM/antiwear additives being used?It seems not many blenders use this additive. It stuck out on the Bel-Ray voa sheet and I didn't know its purpose, thanks for the info.

Drew thats why you never get married.... If I'm gonna have to sell my boat/bike/guitars ect.. and eat mac & cheese every other day I'll do it on my own. LOL....

This is from an additive maker. Search the document for antimony.

You can also Google "antimony crankcase additive" or similar.

I believe Antimony is an EP additive in grease. The lube expert I work with always has me check for Antimony in micropitted bearing surfaces when we suspect an adverse reaction with EP additives.

Antimony is an ingredient in Schaeffers #132, what exactly is it? What does do? Schaeffers calls #132 a moly add, which it doesn't contain much of.
