what is 0w20 oil

0W-20 oil is a type of engine oil that has gained popularity in recent years due to the increasing demand for smaller and lighter engines that deliver more power than ever before. It is a multi-grade oil viscosity that is either a full synthetic or a synthetic blend oil. The "0" in 0W-20 refers to the oils viscosity at startup when the engine is cold, while the "20" refers to how the oil flows through the engine at higher temperatures. Compared to higher viscosity grade oils like 10W-30 or 20W-50, 0W-20 is a much thinner oil that flows easily during cold temperatures. It provides superior low-temperature performance and lubricates engine parts in colder temperatures. 0W-20 oil is typically recommended for diesel and gasoline engines for cold starts and lower oil consumption. It offers benefits such as improved engine performance, fuel efficiency, better fuel economy, and reduced sludge build-up. If 0W-20 oil is not available, 0W-30, 5W-20, and 5W-30 oil grades are at par with 0W-20 oil and can be used instead.
