Abstract

Wear is a continuous loss of material on a surface where there is a contact between the surface of an object with another object which can finally cause a damage. Wear can be prevented by providing a lubricating oil in the two surface rubbing between each other. Lubricating oil is a kind of oil that we can use to overcome the friction in automotive engines. Now days, there are so many brands of lubricant oil That can make a people difficulty to compare between the lubricant oil whish have a good quality and the bad quality. Based on the needs of props that can compare the ubricating oil from the quality side and the major functions, props should used to reduce friction as small as possible. Because of that we did the designing and making the quality testing of lubricating oil by the method of friction. On this props, the quality of lubricating oil can be seen from the value of rotation the ring. The amount of flow that generated from the process of loading an the amount of wear that caused by friction in the process of testing due to the cylinder charge process. In this research, the tested lubricating oil is SAE 20w-50 lubricating oil type. We did the research with props that have been created, where each lubricating oil testing from different brands tested with the same method and process. keywords: quality testing tool of lubricating oil with friction method, friction, wear, lubrication, oil lubrication, design process.
