AMSOIL Synthetic 10W-30 Motor Oil (ATM) and 10 competing conventional, synthetic and synthetic blend 10W-30 motor oils were subjected to a series of motor oil tests. All six tests were completed in accordance with American Society of Testing and Materials (ASTM) test procedures, with the results directly indicating the level of protection and performance provided by each of the tested oils. When testing concluded, AMSOIL Synthetic Motor Oil overwhelmingly emerged as the top-performing oil in the group. No oil outperformed AMSOIL in any of the tests. A comparison also reveals the total cost of using AMSOIL Synthetic Motor Oil is less over 25,000 miles than all the competing motor oils.
