HOW DOES MOBIL 1 COMPARE WITH PLANETSAFE-OT?
Mobil 1 is full synthetic oil and was tested with no additional additives. Mobil 1 shows a rise in friction during the initial 20+minutes of the test run followed by a decreasing friction level. The increasing initial friction occurs during the critical start-up period when most of the wear occurs in an engine. It is likely that the initial increases in friction result in increased temperatures that activate the friction reducing molecules in Mobil 1. Over the 60 minute test period the measured wear for Mobil 1 was 0.40 mm, which is 11% more than the wear observed with PlanetSafe-OT (0.36 mm).
