AMSOIL Premium Protection Synthetic Motor Oil is formulated to provide superior protection and performance in a wide variety of demanding applications. Its unique combination of synthetic base oils and a superior additive package results in a formulation that exceeds the requirements of most gasoline or diesel applications that call for 10W-40 or 20W-50 motor oil. Premium Protection Synthetic Motor Oil is ideal for high-mileage vehicles and high-stress vehicles subject to hot temperatures, heavy hauling, trailer pulling or off-road use. It provides the extra anti-wear protection required by engines with flat-tappet cams and high-tension valve springs. AMSOIL Premium Protection Synthetic Motor Oil offers flexibility and performance beyond conventional oils.
Premium Protection Synthetic Motor Oil is high-viscosity oil engineered to protect against metal-to-metal contact. It resists viscosity loss due to 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. Premium Protection Synthetic Motor Oil helps extend equipment life.
Some may claim that Signature Series is over-engineered. Perfect. It’s not for everyone. It’s for those who want the absolute best engine protection — and it delivers.
Premium Protection Synthetic Motor Oil contains no friction modifiers, making it ideal for motorcycles, maintenance equipment and other wet-clutch transmission applica- tions. 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.
Premium Protection Synthetic Motor Oil is formulated to overcome the thermal deficien- cies common to conventional petroleum oils. Volatilization (burn-off), oxidation and excessive deposit formation from high heat are greatly reduced. Viscosity thickening is controlled and engines run cleaner, promoting cooler operation and long engine life in air- or liquid-cooled engines. In addition, the higher viscosity of AMSOIL 20W-50 Syn- thetic Motor Oil may help reduce motor oil consumption in equipment that experiences higher-than-normal usage rates when lower-viscosity lubricants are installed.
Superior synthetic base oil and additive technology exceeds the requirements of both gasoline and diesel engines. Premium Protection Motor Oil is designed to neutralize acids, disperse soot and last longer in service than conventional oils.
Use in air- and liquid-cooled, large or small gasoline and diesel engines, transmissions and chaincase applications where 10W-40 or 20W-50 oils are required with any of the following specifications: API SL, SJ, SH, SG API CI-4+, CI-4, CH-4, CF, CF-2 ISO-L-EMA Caterpillar ECF-1 JASO MA (Motorcycle) MAN 271/3275 MTU Type 2 Cummins 20071/20072/20076/20077 Volvo, VDS-2, VDS Mack EO-M+, EO-M ACEA A3/B3, E3, E5 MB 228.1, 228.3, 229.1 Detroit Diesel 93K214
