In this informative video, follow along as Royal Purple measures oil film strength with a bearing test using Royal Purple?s Synfilm (http://www.royalpurpleconsumer.com/se....) We compare our Synfilm (with an ISO 68) to a competitor?s lubricant (with an ISO 220) to test the strength of our oil film. In this video we show you up close how each bearing test is affected by different factors, including adding more weights to the test and adding water to the sump. At the end of each test you can see for yourself the marks that are left at different stages of the bearing test. The proprietary additive technology in Royal Purple synthetic oil provides oil film strength and thickness regardless of viscosity. Royal Purple products have an ionic bond which cuts down on friction when it comes to any metal on metal and creates a widespread oil film. You can use Royal Purple products to repair damage, but when you use them from the very beginning it keeps your equipment running like new. When it?s put to the test, Royal Purple?s film strength proves to be 2-3 times better than the average full synthetic oil. Royal Purple synthetic motor oil not only has a high film strength, it also rapidly separates from water, saves energy, has synthetic solvency and a longer oil life, provides excellent corrosion protection, is compatible with other oils and is environmentally responsible.
