CK-4/SN approved, AmazonBasics full-synthetic motor oil offers exceptional quality and convenience.
AmazonBasics full-synthetic motor oil creates a protective coating that helps reduce wear on engine components. By minimizing friction from an engine’s in-contact moving parts (which wastes otherwise useful power), the motor oil helps enhance fuel economy and promotes better power output and performance.
The full-synthetic motor oil helps keep engines clean by minimizing unwanted build-up that can cause damaging rust and corrosion. The motor oil offers a resistance to viscosity and thermal breakdown, plus it helps fight volatility burn-off, which can reduce engine deposits and exhaust emissions.
The motor oil’s grade, as established by the Society of Automotive Engineers (SAE), reflects its viscosity characteristics. The first number—0W and 5W—indicate cold-temperature performance (W for winter), while the end numbers—20, 30, and 40—indicate high-temperature performance (at 100 degrees C).
Depending on driving conditions and needs, choose from the following AmazonBasics full-synthetic motor oil grades (shown in chart below; each sold separately):
