AMSOIL recently put its “ATM” 10W-30 Synthetic Motor Oil up against 10 competing conventional, synthetic and synthetic blend 10W-30 motor oils including Mobil 1 Extended Performance and Pennzoil Platinum. All 10 motor oils were put through six tests which were conducted in accordance with American Society of Testing and Materials (ASTM) test procedures. Not surprisingly, the AMSOIL ATM 10W-30 prevailed in this shootout. What was surprising was how poorly some of the competition fared. Especially the conventional and semi-synthetic motor oils in the cold temp and volatility testing. Now the cynical among you may suspect that because AMSOIL conducted the testing, they therefore tilted the playing field to their advantage. This is a fair assumption, but consider for a second what the competition’s lawyers would have to say about this. This testing took place in the US and if AMSOIL published false data, the resulting lawsuits would likely go on for years. AMSOIL has been “naming names” for decades and their data has never been challenged. Included in the competition are some of the most powerful corporations on the planet (Exxon-Mobil, Shell), so this is no small consideration. The performance of the AMSOIL ATM 10W-30 is quite typical of all of AMSOIL’s Synthetic Motor Oil line.
