Comparative Mobil Oil Test: AMSOIL Synthetic 10W-30 Motor Oil (ATM) and 10 competing conventional and synthetic10W-30 motor oils were subjected to ASTM motor oil test. The competing oils included petroleum-based Castro GTX Drive Hard, Mobil Drive Clean, Pennzoil with Purebase, Quaker State Peak Performance and Valvoline, as well as synthetic-based Valvoline Synpower, Quaker State, Castrol Syntec, Pennzoil and Mobil SuperSyn Multi-Vehicle.
Seven tests were run on the engine lubricants during the motor oil test. The Thin-Film Oxygen Uptake Test (TFOUT) measures the oxidation stability of engine oils. The High Temperature/High Shear Test (HTHS) measures a lubricant’s viscosity under severe operating conditions. The NOACK Volatility Test measures the evaporation loss of oils in high-temperature service. The pour Point indicates the lowest temperature at which a fluid will flow. Total Base Number (TBN) is the measurement of a lubricant’s reserve alkalinity for combating acids. The Cold Cranking Simulator Test (CCS) measures a lubricant’s viscosity at low temperatures and high shear rates. The Four-Ball Wear Test measures a lubricant’s wear protection properties. The impressive test results show that AMSOIL Synthetic 10W-30 Motor Oil outperformed the competitors in each test. Comparative Mobil Oil Test
