Actually don't "just run any 2 stroke oil." That is very bad advice. PWC oil is different from outboard motor oil. Your safest bet is to run the Kawasaki Jet Ski oil.just go run some walmart oil in it... make sure its marine oil tcw3 and read and make sure its for 2 stroke motors and that what I run in mine and its an old 89 jetski.
How so? please explain
