Do new energy vehicles need oil changes?
2 Answers
Pure electric vehicles do not require oil changes, whereas hybrid vehicles still need oil changes. Engine oil possesses lubricating and anti-oxidation properties. Anti-oxidation properties: Under certain conditions, the ability of engine oil to resist oxidative deterioration is referred to as its anti-oxidation property. This determines whether the engine oil is prone to deterioration during use, its tendency to corrode parts and form deposits, and is a crucial factor in determining the service life of the engine oil. Lubricating properties: There is rapid relative sliding between the piston and cylinder, as well as between the main shaft and bearing bush. To prevent excessive wear of parts, an oil film needs to be established between the two sliding surfaces. A sufficiently thick oil film separates the surfaces of the relatively sliding parts, thereby reducing wear.
I just switched to a pure electric new energy vehicle and have been driving it for almost a year without ever changing the engine oil. Since it doesn't have a traditional gasoline engine, the electric motor is directly powered by electricity and doesn't require lubricating oil for components like pistons. Routine maintenance mainly involves checking battery health, tire wear, and brake pad condition. This saves me a lot of time and money, reducing annual maintenance costs by several hundred dollars. However, hybrid new energy vehicles might be slightly different as they have a small engine component that requires occasional oil changes, but pure electric vehicles don't need any at all. Overall, this design is simpler and more reliable, reducing the risk of mechanical failures.
