Iv tried Yamaha Lube, Shell Synthetic, Polaris Premium, Castrol, Artcic Cat Synthetic, and a few more. Ams Oil intercepter and Dominator has blown all the other brands outta the water by far with its Clean burn. Mind you a few of my friends run Klotz and they still foul plugs and their power valves are covered in Gunk and Carbon.
Around where im from Klotz is more expensive by about 3 bucks per Liter. I really dont care what the exhuast smells like. So i still stand with my comment on how its" the best of the best" Anyone who rides snowmobiles and does their own maintence will agree its the best. It doesnt really show when you use it in a banshee engine.
