Hi guys im new to the 2 stroke jet ski world.

I was wondering two things

What type/brand oil should i use in my 1990 Kawasaki 550?

What type of mixture to i do? 40/1? 32/1?

I have a 1998 JS550.

(on mine at least) right at the gas fill cap is a sticker that lists the ratio you should use.

In temperatures above 70(ish) degrees, Kawasaki suggests a mix of 40:1
In colder temperatures you should run richer at 32:1


Here's a pretty good article on oil selection from SeaDoo.
