The straight answer to this question is NO. EVs or electric cars do not need engine oil. However, this doesn’t mean that EVs do not require any type of oil. A traditional engine has moving components like pistons and valves. They have to be kept lubricated constantly for smooth and efficient functioning. That is why they need engine oil.
Having said that, EVs will have to be replenished with other fluids for lubrication and cooling. These are for systems like transmission, suspension, air-conditioning, etc. Bearings in the electric motor, bearings on the wheels, door lock systems, and other parts would need oil for lubrication. Nonetheless, constant oil replacement is not required on these systems and components.
The answer to this lies in the working methodology and functioning fundamentals of the engine. Unlike an Internal Combustion Engine (ICE) that uses fossil fuel, EVs are powered by electric motors. Traditional engines or ICEs have several moving parts that need constant lubrication. Towards reducing wear and tear, maintaining friction-free functioning, and obtaining optimum efficiency. Lack of adequate quantity of oil, of stated specification, can result in engine damage or engine seizure.
The scenario is a bit different in the case of hybrid vehicles. Hybrid cars are installed with both electric motors and traditional engines. The ICEs on the hybrid vehicle will need engine oil. Nevertheless, engine oil replacement or replenishment will not be required as frequently as a traditional engine. Because the electric motor would be handling the majority of power requirements. And the usage of ICE is much lower compared to a traditional vehicle. Further, the ICE in a hybrid car will be smaller than a normal car; therefore, the quantity of engine oil required is also low.
Owners of EVs do not have to worry about engine oil. The only requirement in electric vehicles is the lubrication of specific parts. Additionally, the areas where lubrication is required are closed or sealed. Preventing loss of lubricating oil effectively. Hence, they do not have to be maintained frequently.
Hybrid vehicles have both electric motors and traditional engines onboard. The major work is done by the electric motor. And the ICE is for supporting it whenever required. The frequency of engine oil changes in hybrid vehicles will differ depending on the model. The engine oil replacement periodicity in hybrid cars will vary from 5000 km to 7500 km generally.
The hybrid car will be switching between electric motors and ICE constantly. The frequent changeover may cause increased friction on the components. Due to this, the manufacturer will specify engine oil of the requisite specification. Make sure to replenish the car with the engine oil of the stated specification. Otherwise, you would be damaging the engine.
