Oil is a critical component to making an Arctic Cat ATV, Prowler or Widlcat survive and Arctic Cat offers two choices, ACX 0W-40 Synthetic Oil and ACX 15W-50 Synthetic Oil. Which one should you use? Here’s the difference:

ACX 0W-40 Synthetic – This is an all-season full-synthetic formula recommended for use in temperatures -40F – 100F. ACX 0W-40 Synthetic is a multi-viscosity oil that features excellent cold flow characteristics so it protects engines on startup in colder climates or during cooler seasons such as fall and winter. ACX 0W-40 Synthetic protects engines being used in ambient temperatures up to 100F and is recommended for heavy-duty use in cold temperatures or recreational use and light-duty work applications in warm weather.

ACX 15W-50 Synthetic Oil – If you run your Arctic Cat hard, ACX 15W-50 is the best oil choice. Formulated for use in temperatures between 0F and 130F, ACX 15W-50 Synthetic features long molecule chains that won’t shear or break down under heavy use in hot climates. Use this oil for heavy duty applications or hard trail use in warm weather or in racing applications.
