I found it to be fairly interesting,after years of running premix sleds,and dumping in whatever was handy,at a reduced ratio to keep from fouling plugs I've only had injected sleds for almost 3 years now.
When I got my first "modern" sled,a 93 Cougar the first year I faithfully used Arctic standard non-synthetic oil.
Last year,after putting on many more miles(great riding conditions)I found myself again dumping in whatever was handy at the gas station.
This year a good friend has become a Amsoil dealer so I think I will give that a try,getting a good price from a buddy always helps you know.
I guess we've come a long ways from my Dad ranting and raving about that"Damn Purple Panther ####"we used to get from Arctic Cat
