About 30 years ago at my college bike shop job we were all using Phil grease on our mountain bikes because it was waterproof. one day the Shop owner appeared with a Phil freewheel grease injector tool. So I did a product test on my Trek 850 and used it to grease my nearly new suntour freewheel.
it had the immediate effect of quieting the pawls in the freewheel ratcheting mechanism. I was worried I might have gone too far and waited for the day the pawls would skip on a power climb, but it never happened.
These days I Use whatever I have around to grease things up. Lately it’s a red bearing grease made by Lucasoil.
