2002 GTX DI Fuel Type

[oaklandstone]

Just purchased a 2002 GTX DI with 110 hours and no known problems from a friend of mine. Previous owner ran 93 octane. I've seen 91 is recommended and I've read people using all 3. I'm just a casual rider who purchased to give my twin girls an opportunity to enjoy the water. Will be used mostly for cruising them around and tubing at a local lake. I understand the general overall benefits of using 93 and don't mind the extra cost, but wanted to make sure this was best for the engine since this is my first boat / PWC. Thanks in advance!!

91 non ethanol is fine.

You should be adding fuel stabilizer if the craft sits more than 1-2 weeks. An oz or two of alcohol to fuel will help dissolve moisture, as DI's don't like H2O
in the fuel.
