How Often Should Engine Oil Be Changed for Cars That Are Not Frequently Driven?

[MacCamila]

For cars that are not frequently driven, the engine oil should be changed every six to eight months. Here is an introduction to engine oil: Classification of Engine Oil: Automotive engine oil is divided into three types: mineral oil, semi-synthetic oil, and fully synthetic oil. Mineral oil is the most basic and cheapest type of engine oil, generally classified as SJ or below, and is only suitable for low-end cars or some new vehicles. Functions of Engine Oil: Lubrication to reduce wear: There is rapid relative sliding between the piston and cylinder of the engine, as well as between the main shaft and bearing shells, which can easily cause wear. High-quality engine oil can form a sufficiently thick oil film between the two sliding surfaces, separating the surfaces of the relatively sliding parts, thereby achieving the purpose of reducing wear. Cooling and temperature reduction: Engine oil can carry heat back to the oil tank and then dissipate it into the air, helping the radiator cool the engine.
