Lower unit oil

[findoctorkg]

Can I use regular 80/90 automotive gear oil instead of marine lower unit oil? According to the label, they both meet the same specification and appear to be the same except for the price.<br />Please advise.

I believe the l/u oil is less prone to foaming - in any case you are looking at a couple of bucks a year at most. I would not risk it.

You are better off to use what the engine manufacturer calls for.<br /><br />TMD

The best gear oil we have ever found for force and chrysler outboards is quicksilver high performance gear oil. You can use it in any year and hp. bret<br /><br /> If you need further assistance please email me @ forcepower01@yahoo.com. thanks,Bret
