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.

AMSOIL, the leader in automotive synthetic lubrication, produced the world's first API qualified synthetic motor oil in 1972. Trust the extensive experience of AMSOIL, The First in Synthetics, to do the best job protecting your engine.

• High-zinc formula guards against wear
• Ideal for flat-tappet cams
• Resists deposits to help keep engines clean
• Convenience of use for gas and diesel engines

Features:

• Superior Wear Protection
  Premium Protection Synthetic Motor Oil is a 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.
• Wet-Clutch Compatible
  Premium Protection 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.
• Resists Oxidation and High-Temperature Breakdown
  Premium Protection Synthetic Motor Oil is formulated to overcome the thermal deficiencies 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 Synthetic
  Motor Oil may help reduce motor oil consumption in equipment that experiences higher-than-normal usage rates when lower-viscosity lubricants are installed.
• Extends Drain Intervals in Gasoline and Diesel Engines
  Superior synthetic base oil and additive technology exceed 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.

Applications:

AMSOIL Premium Protection Synthetic Motor Oil is recommended for air- and liquid-cooled, large or small gasoline and diesel engines, transmissions, and chaincase applications where 10W-40 oils are required with any of the following specifications:

• 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
