AMSOIL Performance Test Results - Is AMSOIL really worth the money?
Testing AMSOIL synthetic lubricants in the most demanding environments is our industry trademark.
We push our lubricants to the limit in our state-of-the-art mechanical test lab, in real-world field trials and in the world’s most demanding racing vehicles in an effort to develop the best synthetic oil available. The result is a complete product line that performs as advertised and helps you harness the full potential of your vehicles and equipment.
10 Motor Oils Tested in 5 Performance Areas (G3115) Laboratory bench testing conducted in accordance with American Society of Testing and Materials (ASTM) procedures examined several important areas of motor oil performance, including resistance to deposit formation, wear protection, high-temperature stability, resistance to acid formation and cold-temperature performance.
Stop-and-Go City Conditions (368k PDF) The industry-standard SAE J1376 Fuel Economy Measurement Test (Engineering Type) for Buses and Trucks reveals AMSOIL synthetic lubricants can increase fuel economy in class 8 diesel trucks used in stop-and-go city driving conditions and, in this case, did by 3.15 percent.
for Ski-Doo Rotax E-TEC Engines (G3039) (1.4 MB PDF) AMSOIL subjected INTERCEPTOR® Synthetic 2-Stroke Oil to 50 hours of severe-duty engine testing and two industry-standard ASTM tests to demonstrate that INTERCEPTOR exceeds the performance requirements of high-performance DFI snowmobile engines in severe operating conditions.
Synthetic Diesel Oil (DEO) Fuel Economy (697k PDF) The Environmental Protection Agency (EPA) Federal Test Procedure (FTP) confirms AMSOIL Premium API CJ-4 5W-40 Synthetic Diesel Oil (DEO) improves fuel economy through virtually all driving scenarios compared to conventional 15W-40 diesel oil.
Synthetic Diesel Oil (DEO) Shear Stability (644k PDF) Kurt Orbahn Shear Stability testing (ASTM D-6278) reveals AMSOIL Premium API CJ-4 5W-40 Synthetic Diesel Oil (DEO) maintains outstanding shear stability, even at 4 percent fuel dilution. Note: All oils were available to consumers at the time of testing. Testing completed September 2009. Test results do not represent future formulation changes.
Synthetic Diesel Oil (DEO) TBN and Viscosity (363k PDF) Compared with competing diesel oils, AMSOIL Premium API CJ-4 5W-40 Synthetic Diesel Oil (DEO) provided superior TBN and viscosity retention over 400 hours of severe-service operation in a refuse hauler fleet employing Navistar DT466 diesel engines, which are notoriously hard on motor oil. Note: All oils were available to consumers at the time of testing. Testing completed August 2010. Test results do not reflect future formulation changes.
