Today’s two-stroke snowmobiles direct less oil to critical components, through narrower passages, for longer distances. Oils that thicken at cold temperatures are difficult to pump and can fail to reach components at startup.
Four-stroke engines, meanwhile, are splash-lubricated. Thick oil can cause difficult starts while failing to properly lubricate at startup, increasing engine wear.
AMSOIL synthetic two- and four-stroke snowmobile oils feature outstanding cold-flow properties for maximum engine protection in the coldest weather. They are engineered to exceed the performance requirements of any sled, whethere Polaris, Arctic Cat, Ski-Doo or Yamaha.
