I had a JD800
My dad had a JD800
My uncle had a pair of JD600's
Not sure what the difference between those ever was?
They were both 440's, so ???
Never had any "X's"
I think the X's had slide rails in the mid 70's?
IDK if there was anything else different (color) than that tho?
None of us had any of the newer "Kawi" powered sleds.
One fella I knew bought a Spitfire for his wife, but that's aboot it that I can think of in our circle.

That's not legal. You are allowed to use any two stroke oil that meets spec. I ran shell advance ultra in my skidoo 600 etec never had trouble. Polaris dealer out of oil now too, so won't think twice about dumping it back in Polaris. I still have a few L left. I woke have not signed that
