See How AMSOIL Performs
Whether at work or play, enthusiasts push their UTVs to the ragged edge. They need lubricants that deliver excellent wear protection despite intense heat and stress. To test the performance of AMSOIL ATV/UTV Synthetic Motor Oil, we installed it in a 2018 Polaris* Ranger* and subjected it to an extreme test in our mechanical lab. As the results show, AMSOIL delivered exceptional protection.
Heat And Stress Destroy Lesser Oils
Extreme heat and stress are the biggest enemies to long ATV/UTV life. High-rpm, hot-running engines create extreme conditions that can quickly degrade inferior oils.
Churning engine parts combined with elevated heat create shearing forces that can tear apart, or shear, the molecular structure of the oil. Additionally, the intense pressure the oil undergoes as it’s forced through tight clearances, such as the interfaces of the piston ring/cylinder wall and cam lobe/lifter, also causes viscosity loss due to shear. Oil that has sheared out of its intended viscosity range can fail to form a protective lubricating film on critical engine parts, leading to accelerated wear.
Heat-Seeking Torture Test
We designed the UTV Torture Test too replicate real-world, high-stress conditions.
To achieve maximum power output, a computer-controlled actuator held speed at 45 mph (72 km/h). The tachometer exceeded 6,000 rpm, pushing the engine and transaxle to their limits.
Transaxle temperatures exceeded 280°F (138°C), far beyond normal conditions. Engine oil temperature rose to 280°F (138°C) while the continuously variable transmission (CVT) belt hit 270°F (132°C). In these conditions, lubricants must withstand heat to protect precision parts.
After 100 hours and 4,000 miles (6,437 km) of torture, the engine and transaxle were torn down.
AMSOIL Synthetic ATV/UTV Motor Oil maintained viscosity despite the heat and delivered flawless protection, keeping pistons, cylinders, cams and transaxle gears in excellent condition.
As the images show, the oil protected against piston scuffing despite the extreme conditions. The piston-skirt coating remained intact, while the piston crown and ring lands demonstrated no abnormal deposits or stress. The piston rings remained free and didn’t stick for maximum engine compression and power.
The oil also delivered bulletproof transaxle protection. The transmission gears are clean, virtually free of water and appear like-new despite the extreme heat and elevated rpm.
