Do any of you know what exactly is in the "GM camshaft and lifter prelube" 4 oz bottles? Not the EOS 16oz bottles, I am asking about the small 4 oz squeeze bottles.
I think it says mineral oil, calcium sulfonate and polyisobutene on the bottle. Who knows what that stuff is? Is this all that is in the prelube? No zinc or moly? Has anyone tested this stuff to see if it really has any zinc/moly in it? Thanks.
