Can I mix havoline with seadoo oil?

[super_gtx]

If I put 10w-30 regular old non synthetic oil in my 03 gtx, and it has the seadoo mineral oil for superchargers in it if it will mess anything up. Just changed my oil and my buddy did'nt buy 4 quarts like I said and I have no other alternative as I am headed out to the lake right now.

Use the recommended oils. If you start mixing stuff, you will have a major mess on your hands. I did this on accident (didn't pay attention to the XP-S bottles, just kept buying yellow ones:ack and it took about 8 hours labor and several weeks waiting for parts to get it back in the water.
