Reducing Wear and Friction by Means of Lubricants Mixtures

In this study, two types of lubricants are mixed together in order to maximize wear reduction. Various compositions of mixtures are compared in terms of viscosity index, coefficient of friction and wear scar diameter. Heavy duty engine oil (HDEO) and automatic transmission fluid (ATF) have been used a lubricant condition. The standard procedures used in this study are ASTM D2270 for viscosity test method and ASTM D4172 for four balls tribology test method. Mixture of HDEO and ATF produces better friction resistance as compared to the original HDEO. The benefit of ATF can be used for engine lubrication.
