Why don't Japanese cars burn engine oil?
1 Answers
Japanese cars don't burn engine oil because their piston rings have relatively high tension, which allows them to thoroughly scrape residual oil off the cylinder walls. Here is relevant information about engine oil: 1. Classification: Engine oil is divided into gasoline engine oil and diesel engine oil. The classification includes both quality grade and viscosity grade. For passenger cars, for example, in northeastern regions, 5W-30 or 5W-40 is recommended, while in southern regions, 10W-40 or 15W-40 is suggested. 2. Composition: Engine oil consists of base oil and additives. Base oil is the main component of lubricating oil, determining its fundamental properties. Additives can compensate for and improve the deficiencies in base oil performance, endowing it with certain new characteristics, making them an important part of lubricating oil.
