When it comes to protecting your machinery, not all lubricants are created equal. Whether you are maintaining a daily commuter, a heavy-duty work truck, or a marine watercraft, your engine demands oil that can withstand extreme heat, intense pressure, and grueling friction.
That is where Amsoil stands alone. Decades of rigorous research and premium synthetic engineering ensure that every bottle of Amsoil is formulated to make your engine run smoother, operate cooler, and last significantly longer.
A Formula for Every Need, A Weight for Every Engine
Amsoil doesn’t believe in a “one-size-fits-all” approach. They design specific product lines tailored to how you drive and operate, available in a comprehensive variety of viscosity weights to perfectly match your manufacturer’s specs.
Passenger Car & Light Truck Motor Oils
From ultimate protection to everyday reliability, Amsoil has a synthetic motor oil for your vehicle:
- Signature Series: The absolute pinnacle of motor oil technology. It delivers unrivaled wear protection and stands up to the most extreme horsepower demands.
- XL (Extended Life): Perfect for drivers who want extra protection and boosted performance between extended oil drain intervals.
- OE (Original Equipment): Bulletproof synthetic protection for standard drain intervals, offering exceptional defense against sludge and engine wear for everyday drivers.
Available Motor Oil Weights Include:
0W-20,5W-20,5W-30,10W-30, up to heavy-duty15W-40protection.
Heavy-Duty Gear & Specialized Oils
Protection doesn’t stop under the hood. Critical drivetrain components and marine engines require specialized synthetics built for unique environments:
- Severe Gear® & Synthetic Gear Oils: Engineered for severe towing, hauling, and high-torque demands. Available in essential weights like
75W-90,75W-140, and more to keep differentials running cool. - Amsoil Marine Oils: Formulated specifically to fight rust, corrosion, and high-RPM wear in harsh fresh and saltwater environments.
Why Amsoil Makes the Difference
Every product in the Amsoil lineup is backed by continuous laboratory innovation and real-world testing. When you switch to Amsoil synthetics, you are giving your equipment three distinct advantages:
- Superior Thermal Stability: Amsoil resists chemical breakdown and oil consumption under intense heat, meaning cleaner engines and less sludge.
- Smoother Operation: Advanced friction modifiers reduce internal drag, unlocking maximum efficiency, smoother idling, and optimal fuel economy.
- Extended Component Life: Exceptional film strength keeps moving metal components separated, drastically reducing wear and tear so your engine lasts for the long haul.
From the standard commuter using OE 0W-20 to the commercial hauler running 15W-40 or 75W-90 gear oil, you can drive with absolute confidence knowing your equipment is protected by the best chemistry on the market.
