While searching for plastic compatibility and moly grease I came across many post stating not to use moly grease in wheel bearings, without any context to % of moly, viscosity, or the base soap; just blanket statements. I wanted to bring up Ford actually spec's a moly fortified grease for wheel bearings, and a lot of Japanese motorcycles call for moly fortified grease in needle bearings. If you were to read through this board people would be mislead in which grease to use in these applications. I'm going to point out, read your equipment service manuals, they will specify which type of grease to use. Don't rely completely on Joe Bob I'm a mechanic at Oil is Us and we only use super tacky purple grease because it smells like eucalyptus...
