[QUOTE="bassboy1, post: 285300, member: 55"] It's 80W 90 gear oil. API GL-5 rated. Some say there are differences in the additives making the 'marine' gear lube more water resistant than the 'automotive,' but I've yet to see any differences in the MSDS that would suggest that. Any auto parts store or Walmart would have it both in a bottle labeled for automotive use, and one labeled for marine use (and labeled with a higher price). Take your pick. I personally don't feel there is anything to be gained by going to synthetic gearlube on these smaller engines. The difference would be immeasurable, for all intents and purposes. [/QUOTE]
