AMSOIL Premium Protection 10W-40 Synthetic Motor Oil is high-viscosity oil engineered to protect against metal-to-metal contact. It resists viscosity shear and is formulated with a heavy treatment of zinc and other anti-wear additives for excellent protection of gears, bearings, cam lobes and other high-pressure components in engines and transmissions. AMSOIL Premium Protection Synthetic Motor Oil helps extend equipment life.
AMSOIL Premium Protection 10W-40 Synthetic Motor Oil contains no friction modifiers, making it ideal for motorcycles, maintenance equipment and other wet-clutch transmission applications. Formulated to prevent clutch glazing and slippage, it helps ensure smooth clutch engagement and long-term, dependable transmission operation. Premium Protection Synthetic Motor Oil reduces clutch wear for extended transmission life.
The secrete is built into the formulation to overcome thermal deficiencies.
Volatilization (burn-off), oxidation and excessive deposit formation from high heat are greatly reduced. Viscosity thickening is controlled hence engines run cleaner, promoting cool operation extending engine life in air or liquid-cooled engines.
Superior AMSOIL synthetic base stock and additive technology exceeds the requirements of both gasoline and diesel engines. AMSOIL Premium Protection Motor Oil is designed to neutralize acids, disperse soot and last longer in service than conventional oils. It virtually restores performance in your vehicles as you drive. Premium additive packages only because AMSOIL is devoted to our customers therefore you get something from this oil not available from others!
The list below contains the specifications which the AMSOIL Premium Protection 10W-40 Synthetic can be used. It’s perfect for air and liquid-cooled, large or small gasoline and diesel engines, transmissions and chaincase applications where 10W-40 oils are required.
AMSOIL Synthetic 10W-40 Synthetic is compatible with conventional and synthetic motor oils. Mixing AMSOIL motor oils with other oils, however, will shorten the oil life expectancy and reduce the performance benefits. Consequently mixing this with other products or viscosities you can kiss the extended drain intervals goodbye! Aftermarket oil additives are not recommended for use with AMSOIL Synthetic Oils. (Not wise).
AMSOIL Synthetic 10W-40 Premium Protection Motor Oil is recommended for extended intervals in unmodified, mechanically-sound vehicles or equipment as follows:
Diesel Engine Service
•Normal Service – Up to 25,000 miles or one year, whichever comes first, or longer based on oil analysis.
•Severe Service – Up to 15,000 miles or one year, whichever comes first, or longer based on oil analysis.
•Normal and Severe Service – Up to 15,000 miles or one year, whichever comes first, or longer based on oil analysis.
Motorcycles, Small Engines, Stationary Engines, Heavy Equipment and Other Applications
•Extend drain intervals based on oil analysis or follow the manufacturer-recommended drain interval.
AMSOIL Ea Full-Flow Oil Filters are designed for extended drain intervals. They stop smaller particles, flow more oil and last longer than regular filters. For best performance, use AMSOIL Ea Full-Flow Oil Filters and replace at the time of oil change. Other oil filters should be changed at standard OEM* intervals.
