Tough enough to tackle King of the Hammers with Brad Lovell, Bryce Menzies and Kyle Chaney; easy enough that you won’t need their pit crews to do the work for you. 

ATVs and UTVs are used to perform demanding chores and tackle tough terrain. They are frequently driven in low gear, pulling loaded trailers and other necessities to get the job done, in all types of weather on variable surface conditions.

Both slow engine operation under heavy loads and high-speed racing increase heat and stress on the engine. AMSOIL Synthetic ATV/UTV Motor Oil is engineered with robust synthetic base oils for improved engine protection, even in the toughest conditions.

Heat degrades motor oil

The primary job of motor oil is to prevent wear. The extreme heat created by stresses placed on the engine can cause conventional mineral oils to lose viscosity and become thinner, allowing metal-to-metal contact inside your engine.

Heat also creates sludge and deposits much easier in conventional oils. Sludge clogs oil passages, preventing effective engine lubrication and increasing the chance of wear. Performance-robbing deposits can cause the piston rings to stick or interfere with valve operation, leading to reduced engine compression. As sludge and deposits accumulate over time, your engine makes less power and can even be damaged.

The solution

AMSOIL ATV/UTV motor oil uses tough synthetic base oils that resist extreme heat and maintain a strong protective barrier between metal parts, delivering better performance and lasting longer than conventional oils. It’s even more important to upgrade to high-quality AMSOIL Synthetic ATV/UTV Motor Oil if you’ve modified your machine for more power or enhanced productivity.
