Excessive wear impedes a vehicle’s performance and can lead to engine failure.
AMSOIL Signature Series 0W-20 Synthetic Motor Oil was subjected to the 100-hour Sequence IVA Engine Test (ASTM D6891), an industry standard for motor oil performance. Sequence IVA evaluates an oil’s high-temperature performance, including oil thickening, piston deposits and engine wear. Signature Series delivered 75 percent more protection against horsepower loss and wear than required by a leading industry-standard*.
