Abstract

These analyses of lubricant use types of the engine oil in motorcycle, there are three types of engine oils are normal (20W-40), semi synthetic(l5W-40) and fully synthetic ( 15W-50). To analysis the performance of the lubricant, the method use is Four Ball Tester (extreme pressure) E.P machine to obtain the result. From this experiment there are two brands X and Y with the same grade is analysis to be compared the quality. The test uses the applied load to give different size of scar diameter to the ball. The size of the scar will be compare to analysis the result based on the graph of applied load versus scar diameter will be obtained. The load in this test is increased until reach the welded point that shows the maximum load can be applied to the lubricant. The results that compare from the analysis shows the maximum load (welded point) is at 160 kg for grade 20W-40, for 15W-40 and 15W-50 can reach the 200kg until 250kg load. The friction analysis also shows how the lubricant prevent the steel ball from wear, the less friction produce the higher quality of lubricant.
