I've asked questions about Amsoil 4-stroke and diesel oils on here before because I didn't feel like I knew much about it, not just technical knowledge but even from just a user experience standpoint.
When it comes to Amsoils 2-stroke oils, I am still not knowledgeable on the technical side, but have loads to offer from a user experience standpoint. Amsoil, hands down, is head and shoulders above even other synthetic oils that I have used.
Take this for example: I owned a Polaris Scrambler 400 2 stroke ATV. I was running the expensive Polaris synthetic oil. If the blasted thing sat for more than a month without being cranked, I had to take it in to have the jets cleaned. I eventually sold the ATV, and bought my first PPG rig. I bought it used from a guy who had never had any trouble out of it. I started using my leftover Polaris synthetic oil. If my PPG motor sat for more than 2 weeks or so, it would not crank. It would be gummed up so bad it was ridiculous. I eventually was recommended to try Amsoil in it. Not only did the problem clear itself up by switching to Amsoil, I was getting about 15 pounds more thrust and was able to stay in the air about 30 minutes longer on a tank of gas. CHT temps also decreased dramatically. 30 minutes of flight time added to a normal 1 hour and 50 minute flight time is a SIGNIFICANT increase.
I can't say bad or good about Kawasaki's oil, but I can sure say that Amsoil did the trick for my high performance 2 strokes, even compared to another synthetic.. comparing it to dino 2 stroke oil just plain isn't fair.
