Electric cars need oil? What are the fluids used for the maintenance of electric vehicles

Adding oil to the engine allows it to run without seizing or overheating. To keep the car engine running smoothly, the microscopic metal flakes that develop in the oil due to metal-to-metal friction must be removed after some time, so you must remove the oil and replace it with new ones. new or even fresh oil.

In the electric vehicle, however, one will occur. Electric vehicles, like the Chevy Bolt EV, are powered by an electric motor as well as a battery. There are absolutely no moving parts such as pistons, valves, motors or any other components that require lubrication. Therefore, frequent oil changes are generally not necessary for electric cars.

Why don’t electric vehicles need oil?

Electric vehicles do not need to run on petroleum-based fuels like gasoline-powered vehicles. The grease is used to lubricate the motor components of electric cars. The oil change becomes necessary for the EV with the gearbox.

The oil is essential for lubricating the massive moving components of traditional gasoline automobile combustion engines. Because engine pistons, valves and other moving components must move smoothly against each other at higher speed, oil must be introduced into an engine to lubricate the interactions within tight tolerances.


The engine runs without stopping or overheating when putting oil on it. Microscopic metal flakes accumulated from metal-metal interactions in the oil must be removed after a short period of time. Drain the old oil and replace it with new oil. Keep your engine running smoothly.

Electric automobiles, in their most basic form, are powered by batteries and electric motors. Because there are no valves or pistons, or alternative moving parts to lubricate in electric vehicles, there is absolutely no requirement for frequent oil changes.

The oil change on the electric vehicle vs the conventional vehicle

Electric automobiles have entirely different gearboxes; therefore, you do not need to change the oil when servicing them. This is because traditional gasoline vehicles require oil to wax the moving components of electric vehicles. Pistons, moving engine components and valves must interact seamlessly at high speeds.

Therefore, oil changes are necessary for an engine to maintain tight contact tolerances. All metal-to-metal relationships result in the formation of atomic metal flakes in engine oil, requiring the exclusion of old engine oil and the addition of new engine oil.

What fluids do electric vehicles need?

Although the electric car requires less maintenance, this does not mean that you should ignore it. Don’t forget that there is nothing called the maintenance-free automobile. Although you never need to replace the oil in the EV, you should still perform periodic checks of these fluids in the EVs:

Cooling liquid

Coolant heat is a major concern for electric and gasoline-powered automobiles. Coolant is needed to regulate the heat generated by the electric car’s lithium-ion battery. This is an important area where the electric car and the thermal vehicle follow the same procedures.

Check overall coolant levels in the car’s battery, cabin heater, and inverter. Although this cabin heater is unimportant, two components are still extremely vital.

If you’ve ever heard of an electric car fire, it’s probably caused by an overheated battery. As a result, you can keep coolant levels high and prevent its battery from exploding.


Brake fluid

While the electric car uses brake pads, these rarely need to be replaced thanks to the vehicle’s regenerative braking technology. This particular technology reduces brake wear solely by converting the kinetic energy of the moving vehicle into electrical energy for its battery. Essentially, its system serves as the primary means of slowing the car down and reducing brake pad wear.

The braking system of the electric car happens to be an essential piece of power generation equipment. Typical maintenance for an e-car is simply to ensure that its braking system is operational, which is essential because, in addition to creating electricity, it is also the primary means of slowing your vehicle.

Smooth transmission


The e-vehicle direct drive or multi-speed transmission may require fluid changes during the life of ownership. And it is simply essential to consult the owner’s manual to determine the recommended intervals for performing this service on specific electric vehicles.
