5/7/2023 0 Comments Redline oil![]() It is not an indication of how well the oil resists thermal breakdown.įlash point is the temperature at which an oil gives off vapors that can be ignited with a flame held over the oil. These numbers can only be compared within a viscosity range. This is one major property of an oil that keeps your bearings happy. Higher numbers indicate a low change, lower numbers indicate a relatively large change. Viscosity Index is an empirical number indicating the rate of change in viscosity of an oil within a given temperature range. See here, especially at 3-3:Īnd check this out, I copied the table below: īased on the numbers the following seem to be the best in the lot for 10-30W when you compare the importance of the viscosity index with the flash point together: the new Amsoil, followed by Mobil 1 with a tie with RedLine, then Valvoline Synpower with Unocal Super. After seeing so much advertising over the years for this lubricant, we were extremely surprised by the results and are sure you will be, too.Īctually, I found a great source to answer your question. It took only 2lb to break through the oil film on the race, with the test leaving an 8mm scar on the test bearing and slight scorch marks from the heat caused by metal on metal friction. It was out-performed by oils half the price. I have to say that we were truly astounded by them as well. The results truly speak for themselves in the case of Mobil 1. They did mention that the engine bearing have much larger surface area then their test so the wear characteristic will not be anywhere as severe. The idea is to demonstrate the long term wear in short period of time. It shown a lot of wear in the test compare to other brands of motor oil. The most surprising part is how poorly the Mobil 1 performed. Its a test of 18 different brands of motor oil.
