How Long Can Full Synthetic Oil Last?
2 Answers
Full synthetic oil can last for 10,000 kilometers. Full synthetic oil is designed to achieve better lubrication effects by chemically synthesizing various oils based on base oil. Synthetic oil manufacturers produce different types of oil according to user requirements, and the composition of synthetic oil can be adjusted based on its intended use. Engine oil primarily contains anti-wear additives, detergents, dispersants, and multi-grade viscosity index improvers. It is used for lubricating internal combustion engines. The main functions of engine oil are to reduce friction and wear on moving parts, remove sludge and varnish from the engine, neutralize acids produced by fuel and lubricant oxidation, improve piston ring sealing, and cool the engine by carrying away heat from moving components.
I've been driving myself to work for over a decade and found that full synthetic oil lasts much longer than conventional oil. Generally, it can go 8,000 to 15,000 kilometers or about a year, but this isn't set in stone. For example, I drive a hybrid with mostly city commuting, so I check the oil condition every 5,000 kilometers. If you frequently drive on highways or long distances, the oil might last even longer. However, don't forget to consider driving habits—if you often brake hard or deal with stop-and-go traffic on short trips, the oil wears out much faster. Environmental and time factors also matter; in high-temperature areas or if the car sits too long, the oil can oxidize and degrade. To save money and hassle, I recommend regularly checking your car manual's recommendations and combining mileage with time. In short, frequent checks prevent issues, and protecting the engine keeps your car running smoothly.
