It is an important fact to reduce the wear of the engine parts and therefore improve the fuel economy in order to use the automobile engines effectively. Especially the engine oil plays a crucial role for minimizing the wear amount. Employing the suitable engine oil extends the service life of the engine and provides better fuel-air combustion by partially preventing the wear of moving parts. In this study, engine of a Fiat branded Palio model automobile was designated as the test engine. The wear behavior of the piston-cylinder was investigated by using two different engine oils which are named as Mobil 1TM ESP 0W-40 and Mobil SuperTM 3000 X1 5W-40. Mobil 1TM ESP 0W-40 type engine oil is also stated in the manual of the vehicle as the recommended engine oil. For both of the engine oil types, the test engine was operated for 144h at 3000, 4000 and 5000 cycles. In order to understand the effect of lubrication better, tests were carried out by using a standard engine mechanism and also an oil pump supplemented engine mechanism. A comparator set and micrometer was used to measure the wear amount of the inner surface of the cylinder and the engine oil types were compared according to the obtained
results. It was found that Mobil 1TM ESP 0W-40 type engine oil enabled less wear in the cylinders and helped the engine to enhance its working performance.
