What kind of gas and oil should i use in a 1996 seadoo gtx?

I know that a higher octane is probably recommended for best performance, but with prices being so high i wouldn't mind using regular 87 if it will not hurt it. also, what kind of oil can i use. is there an alternative to the expensive oil that the manual says to use? i own a dirtbike and the manual says to use kawasaki oil which is 40 a gallon, and i use this stuff from wal-mart that is 40 dollars for 5 gallons and the oil is the same quality. thanks|||It is best to use OEM TWC-3 2 cycle oil recommended for your 2 stroke outboard or jetski. The reason is some 2 cycle outboards and PWC's are specifically designed to run with a certain level of lubrication that often times is not enough with aftermarket TWC-3 2 cycle oils. Also, OEM TWC-3 2 cycle oil is specially made to work with their oil injection systems too, getting a cheap TWC-3 oil might cause it to fail.





The best advice I can give you is go to several Seadoo dealerships and/or service shops and ask on whether OEM oil is necessary for your PWC's model and year. 90% or more of them will say, buy the stuff from the PWC's manufacturer for it.





So in short, only use OEM 2 cycle oil recommended for your PWC unless specifically told differently ONLY by a Seadoo dealership or Seadoo service shop which can back that claim up with evidence.





If you don't heed my advice, at least buy Quicksilver Premium 2 cycle outboard oil. Its the only aftermarket TWC-3 2 cycle oil I've ever trusted. The cheaper stuff is just plain engine wrecking junk in my experienced opinion.|||87 octane and Wal-mart oil is fine.





I would eliminate the oil injection and pre-mix. I do on all my skis. The Sea-Doos are not as failure prone as other skis, but will stop oiling.





If you are in a warranty period you should (but not mandatory) use OEM stuff, but I believe a '96 warranty has already expired!|||I have a 1996 and a 2000 gtx, both run extremely well on 87 octane and Quicksilver from Walmart. Put new plugs in and charged battery, start every year, end of year I just put Sta-bil in the tank of gas and spray plugs with WD-40.
