Well, I got the '99 SnoPro!

 Too good of a deal to pass up. I forgot to ask the guy what oil he used. I've heard the power valves on this model aren't the best, so I was wondering what oil you think would be best for this sled.
Thanks for your replies.

Amsoil regular or racing 2000.  By far the best oil for any sled.

Castrol Syntec is also good at keeping the valves clean but it has a stong smell that smells really good if you like it but could be sick to someone else.  Its also a little cheaper.  

I run amsoil in my mach and castol in everything else.  I pulled the RAVE valves on my 98mxz 500 after 7000km and the valves were still clean using castrol.  Engine also has 150 compresion in both cylinders which is the same as the day i got it.

It also helps to drive hard.
