Electric cars do not require oil changes because they do not have internal combustion engines that rely on motor oil for lubrication. Unlike gasoline or diesel vehicles, which use oil to reduce friction and wear in their engines carsflow, electric cars operate using electric motors that do not have moving parts requiring oil. However, EVs still require regular maintenance, such as checking the battery, brakes, and coolant for the thermal management system. While oil changes are unnecessary, keeping up with other essential maintenance ensures the longevity and efficiency of an electric vehicle.
