mercury high performance

[jigguy]

Can anyone tell me if I can use this high performance lower gear lube in my 115 96 mariner motor? How about a 25 hr mercury motor? I have always used the standard stuff but someone had a jug of the high performance on sale. Obviously I would be draining out the old oil and adding the new stuff.

What brand and type is it ? If you are uncertain, then keep the one you have, the $ 5.00 saved won't go very far if you wreck your lower unit.

I actually assume it would be fine but you make the judgement.

Yes you can use it just don't mix it with standard gear lube. Here's the info from the Mercury HSOforum.
