The electric vehicle (EV) revolution has gained momentum, with Tesla leading the charge as the world’s largest EV manufacturer.
With traditional cars, whether they require oil is straightforward, as it’s a fundamental component of the engine.
What about Tesla? Does a Tesla have any oil?
Tesla electric vehicles do not require any oil to operate, as they are powered solely by electricity. However, Tesla vehicles may have power steering and brake fluid necessary for the steering and braking systems to work properly.
The answer may seem obvious to some, but for those unfamiliar with the intricacies of EVs, the question raises important points about the nature of electric cars and the components that make them run.
In this article, we’ll take a closer look at the role of oil in traditional cars and explore the various components of a Tesla to determine whether or not oil plays a part in their operation.

Do Tesla Cars Have Fluids?
As a 100% electric vehicle, Teslas do not have fluids in the same way that traditional gasoline-powered cars do.
However, some fluids are necessary for Tesla’s proper operation and maintenance.
One of the most important fluids in a Tesla is the coolant.
While it is not used to cool the engine as in a traditional car, it is still used to regulate the temperature of the battery and electronics systems.
This is important because the battery and electronics generate significant heat, which you must manage to ensure the car runs safely and efficiently.
In addition to coolant, Teslas also require windshield washer fluid to keep the windshield clean and clear.
This is particularly important for the Autopilot system, which relies on a clear view of the road ahead to operate safely.
Below is a complete list of fluids found in Tesla vehicles and an explanation of their function:
1. Coolant
Tesla cars use coolant to regulate the temperature of the battery and electronics systems. The battery and electronics generate a significant amount of heat, which needs to be managed to ensure the car runs safely and efficiently. Coolant flows through several pipes and hoses to dissipate heat and prevent overheating the battery and electronics.
2. Brake Fluid
Tesla cars use brake fluid to operate the hydraulic brake system. When the brake pedal is pressed, the brake fluid flows from the brake master cylinder to the brake calipers, which squeeze the brake pads against the brake rotors to slow or stop the car.
3. Windshield Washer Fluid
Tesla cars use windshield washer fluid to clean the windshield and ensure visibility while driving. When the wiper control is activated, the fluid is stored in a reservoir and pumped through a nozzle onto the windshield.
4. Gearbox Oil
Tesla cars have a gearbox responsible for transferring power from the electric motor to the wheels. The gearbox requires lubrication to operate smoothly, and Tesla uses a specialized synthetic oil formulated to provide high performance and long-lasting protection to the gears and bearings in the gearbox.
5. Wheel Bearing Grease
The wheel bearings in a Tesla car allow the wheels to rotate smoothly, requiring proper lubrication to prevent wear and damage. Tesla uses a specialized grease designed for the high temperatures and loads that the wheel bearings experience.
6. Power Steering Fluid
Tesla cars may have power steering fluid, which is necessary for the power steering system to work properly. Power steering fluid helps to reduce the effort required to turn the steering wheel, making the car easier to maneuver at low speeds or in tight spaces.
While Tesla cars do not have the same fluid requirements as traditional gasoline-powered vehicles, they still require several different fluids to operate and maintain their various systems properly.
While these fluids may seem minor compared to the many fluids used in traditional cars, they are still important in keeping a Tesla running smoothly.
Does A Tesla Require Lubrication, And What Kind?
As an electric vehicle, a Tesla does not have a traditional engine that requires lubrication. Therefore, there is no need for oil changes or lubrication of engine parts. However, there are still some parts in a Tesla that require lubrication.
The gearbox transfers power from the electric motor to the wheels and requires lubrication to operate smoothly. However, the type of lubrication used in a Tesla uses specialized gearbox oil for their electric drivetrains.
Another component that requires lubrication in a Tesla is the wheel bearings. The wheel bearings allow the wheels to rotate smoothly, and as such, they require proper lubrication to prevent wear and damage.
Tesla uses a specialized grease designed for the high temperatures and loads that the wheel bearings experience.
In summary, while a Tesla does not have an engine that requires traditional lubrication, some components still require specialized lubricants to operate smoothly.
The gearbox and wheel bearings are two such components that require regular maintenance to ensure the car runs safely and efficiently.
What Kind of Gear Oil Do Teslas Use?
Tesla uses a specialized gear oil in their vehicles, designed specifically for their electric drivetrain.
This oil is a synthetic fluid formulated to provide high performance and long-lasting protection to the gears and bearings in the gearbox.
The gear oil used in Teslas has a high viscosity index, which means it maintains its fluidity even at high temperatures, ensuring that the gearbox operates smoothly and efficiently.
Additionally, the oil has excellent thermal and oxidative stability, which helps to prevent wear and extend the life of the gearbox components.
What Kind Of Brake Fluid Does Tesla Use?
The brake system in a Tesla vehicle is composed of several different components, including the brake pedal, brake booster, master cylinder, calipers, and brake pads.
To ensure the safe and reliable operation of the brake system, Tesla uses a specialized brake fluid designed to provide optimal performance and longevity.
The brake fluid used in Tesla vehicles is a DOT 4 brake fluid, a glycol-based fluid that meets the highest brake fluid performance and safety standards.
DOT 4 brake fluid is known for its high boiling point, which helps to prevent vapor lock and maintain the proper function of the brake system, even under extreme temperatures.
While the brake fluid in a Tesla vehicle does not need to be changed as often as the brake pads, it is still recommended to change it periodically to maintain optimal brake performance.
Tesla recommends replacing the brake fluid every two years or 25,000 miles, whichever comes first.
Proper brake fluid maintenance can prevent corrosion and maintain the integrity of the brake system over time.
What Lubricant Is In The Tesla Electric Motor?
As an electric vehicle, Tesla does not have an internal combustion engine, so there is no need for traditional engine oil.
However, the Tesla electric motor still requires a lubricant to keep the moving parts running smoothly and prevent wear and tear.
The lubricant used in the Tesla electric motor is a special grease designed specifically for electric motors.
This grease is formulated to withstand the high temperatures and loads the motor experiences while providing long-lasting protection and reducing friction.
The Tesla electric motor uses a permanent magnet design, which means that the motor has a fixed magnetic field that interacts with the electric current to generate torque.
To keep the motor running smoothly, Tesla uses a synthetic polyalphaolefin (PAO) grease that is compatible with the materials, including the neodymium magnets.
This grease is designed to provide long-lasting protection against wear and corrosion while maintaining its performance over a wide range of temperatures.
Conclusion
Tesla electric vehicles do not require traditional engine oil as gasoline-powered cars do.
However, fluids and lubricants are still necessary for Tesla’s proper operation and maintenance, such as coolant for the battery and electronics, specialized gearbox oil for the gearbox, specialized grease for the wheel bearings, and brake fluid for the brake system.
These fluids and lubricants play an essential role in keeping a Tesla running safely and efficiently, and they require regular maintenance to ensure optimal performance.
Overall, the use of specialized fluids and lubricants in Teslas highlights the unique nature of electric vehicles and the importance of proper maintenance.
As electric vehicles continue to grow in popularity and become more widespread, it is crucial to understand the components that make them work and the maintenance required to keep them running smoothly.
Tesla’s use of specialized fluids and lubricants is just one example of the innovation and attention to detail that has made them a leader in the electric vehicle industry.
