HERES A GOOD ONE. I RECENTLY BOUGHT A 91 WAVERUNNER WITH A 650 IN IT. GOT A GREAT DEAL $500.00 FOR A RUNNING SKI. THE SELLER HANDED ME A FEW QUARTS OF OIL AS I WAS LOADING IT UP AND SAID THAT IS WHAT HE HAS RUN IN PREMIX FOR THE LAST FEW SEASONS. IT WAS QUAKER STATE 30 WT MOTOR OIL.I LAUGHED AND SAID YOUR JOKING RIGHT. HE WAS SERIOUS. I EXPLAINED WHAT OIL IS SUPPOSED TO BE USED AND HE JUST SHRUGGED HIS SHOULDERS AND HAD NO IDEA WHAT I WAS TALKING ABOUT. JUST SAID THAT IS WHAT WAS ALWAYS USED IN HIS OLD OUTBOARDS. MAYBE 40 YRS AGO I GUESS. HE IS ABOUT 70 YRS OLD. ANYWAY THE QUESTION I HAVE IS IS IT POSSIBLE THIS CAUSED ANY MAJOR DAMAGE THAT HAS NOT SHOWN UP YET. COMPRESSION IS 140 ON BOTH CYLINDERS AND RUNS FINE. IM ON YAMALUBE NOW AND HAVE BEEN SINCE I GOT IT. I PUT APPROX 10 HRS ON IT THIS WEEKEND NO PROBLEM.

Luckily on a 650, it's pretty beefy. It wouldn't surprise me if it lasted some time on that oil, but not forever. On a newer ski, it would blow on one tank.SBT Tech Support is here to help with your problems.
