Non synthetic oil
Just something to think about. On another popular jet ski site the recommendation for seadoos is to run non sythetic oil in the supercharged models.

That is only because of the super charger clutch. You can run the AMSOIL Synthetic Oil that is safe for the super charger clutches on the Sea-Doo's.

HEY! Mr 800AMSOIL! Please visit us in these threads to discuss problems using AMSOIL and the fuel in oil problem. It seems many of us anal retentive Amsoil users are having more problems with this than the dino-oil users: http://greenhulk.net/forums/showthread.php?t=37485 and http://greenhulk.net/forums/showthread.php?t=37180

Here is a post from TurboDave. http://greenhulk.net/forums/showthread.php?t=33712
He also has the fuel dilution problem. He also did a leak down test. He only has 4% passing by the rings, which is great. This is not a oil or ring sealing issue. IMO I would use a synthetic oil, granted it is more $$. It will give you more protection that a petroleum oil, especially with the fuel dilution issues. I do not care whose synthetic oil you use, but I would use a synthetic even if it cost you another $12.00 per oil change. This is the life blood of any engine. I hope this helps.

Synthentic oil chemically binds with the metal in an engine. It fills
up the microscopic holes and scratches. This is one of the reasons
it lubricates so well. It does not breakdown nearly as easily as a
petroleum based oil. It handles heat far better at any viscosity rating.
If there was ever a machine that needs synthetic, it's a Jetski! High RPM's,
infrequent use, harsh moisture laden environment, forced induction, etc.
I only needed 3 quarts at my last change, so at $5/qt that's $15 for Mobil
1 bought at Costco. Amsoil's extra additive packages are probably good
insurance for a few bucks more.
Once the elusive R&D fix appears we'll have an answer. The gas doesn't
appear to be blowing past the rings, I think it's coming from the routing of the emmision plumbing back into the air intake. However I don't experience it so for me it's just conjecture! Of course I don't run anything WOT for any length of time....including me!

I use only AMSOIL in my GPR, and will be switching from Mobil 1 to AMSOIL in the Ultra. Tomgtv is right, it's only a couple of bucks per change - a small price to pay given the conditions the ski operates in.

doesnt the fuel tank vent? I know its not allowed to vent to the atmosphere. Also most injection systems have a return line to the fuel system. There is alot of other "stuff" as well that is considered emmision systems that people dont realize. Not saying the ski has any of this but somthing to think about. I think the oil in gas issue is a combination of things. Mostly emmisions related somehow. I do have the problem but it is getting better with time. We all await the R&D "fix". I still love my 250x and think it is the best ski for me. Although the cruise option is nice on the yami. I still would never sell my 250x and switch for the yami just for the cruise control option.
