Warning About Gear Oil
GEARPLUS® SAE 80W-90 GL-4 Important .pdf file click to download
Sadly, Pennzoil no longer makes GEARPLUS® SAE 80W-90 GL-4
Never the less, the following still holds true:
All modern gear oil available today in local retail outlets is GL-5 grade. GL-5 grade gear oil contains sulphur compounds that attack brass and bronze. BMW transmissions and final drives made before 1992 contain bushings and thrust washers made of these metals. Any brand of gear oil that is GL-5 rated will attack bushings and thrust washers. Bench Mark Works LLC, I use only GL-4 gear oil and we have it available for sale to our customers at the online parts store.
