Premium Protection 20W-50 Synthetic Motor Oil

Product code : AROQT-EA

For use in both diesel and gasoline engines. Ideal for applications where the extra protection of a higher-viscosity oil is desired. The higher viscosity may help reduce motor oil consumption in equipment experiencing higher than normal oil usage rates while running lower viscosity lubricants.

Premium Protection 20W-50 Synthetic Motor Oil



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

Superior Wear Protection
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.

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 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.

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 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

MIXING AMSOIL
AMSOIL Synthetic 20W-50 Premium Protection Motor Oil 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. AMSOIL does not support extended drain intervals where oils have been mixed. Aftermarket oil additives are not recommended for use with AMSOIL Synthetic Oils.

SERVICE LIFE
AMSOIL Synthetic 20W-50 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.

Gasoline Engine Service
–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.

    By  MARIO,  a  Verified Buyer  from  Denver Colorado  on  July 06, 2022
    I've been using AMSOIL for all of mu vehicles for quite some time now, a couple of years ago I saw a video by a YouTube on the channel "Project Farm". He conducts independent testing on a variety of different products. I came across a video where he tests AMSOIL along other popular brands and AMSOIL came on top, this just affirmed my opinion on AMSOIL and I'm glad I use their products on my vehicles. 2010 Ford Fusion Hybrid 1997 Ford F-350 7.3 2013 Land Rover LR4 5.0 1997 Volvo 850
