Used in 2009 Ski Doo 600 HO ETEC after last season both plugs fouled. We suspected injector/ fuelling issues, and after the first engine blew we began trying various products. Even though we followed the manual for service intervals, I have yet to be let down by amsoil's quality above all other products, and this product is no different. After pouring half a quart (~16 oz) into the 10.6 or so gallon fuel tank, that day's trail ride was unlike any other. Also owning a 2015 600 carb Ski Doo, we both noticed with the same treatment that the carb was almost as responsive as the etec! Something neither of us believed possible. Both sleds, having well over 5k both now feel like new!
