Electric cars (EVs) are very different from regular cars that use gas, so they need special lubricants and fluids. Gas cars need engine oil to keep their engines running smoothly, but electric vehicles don’t because their motors don’t create as much friction.
Even though electric cars don’t need engine oil, they still use other fluids to work well. These fluids help keep the battery cool, protect the motor, and make the car more efficient. In this article, we’ll talk about why lubricants are essential for electric vehicles and how they differ from the oil used in regular vehicles .
Do Electric Cars Need Engine Oil?
No, electric cars don’t need engine oil like gas-powered cars do. Electric engines create much less friction, so they don’t require oil. However, electric vehicles still use other fluids.
Why Don’t Electric Vehicles Need Engine Oil?
To understand why, let’s compare combustion engines and electric engines. Combustion engines have many moving parts, like crankshafts, valves, pistons, and camshafts. These parts work together to make the car move by turning the pistons’ up-and-down movement into a rotating motion for the wheels.
The friction between all these moving parts causes heat and energy loss, which can wear out the engine over time. Engine oil helps reduce that friction, keeps the engine cooler, and prevents damage. But since electric motors don’t have as many moving parts, they don’t need oil.
Oil is really important in regular combustion engines because the engine could get damaged after just a few miles.
Electric engines are simpler. They make the wheels move using a rotating motion from the rotor, which is powered by a magnetic field. Electric motors don’t need all the complicated parts like combustion engines. That’s why electric vehicles don’t need engine oil but still require other fluids to work properly. At Fubex Lubricants, we ensure all engines, including electric ones, have the proper fluids to keep everything running smoothly.
EV-Fluids for Electric Vehicles
Electric vehicles (EVs) are becoming more popular because they are better for the environment and are the future of vehicles. EVs need special fluids and greases for engines, batteries, inverters, transmissions, and other parts. These fluids need to have unique qualities to work well in electric cars.
Fubex offers a wide range of EV fluids for electric cars and motorcycles. These fluids are designed to meet the growing demand for eco-friendly vehicles.
They help keep the car’s batteries cool, which is essential for charging them the right way. The fluids also help improve how well other vehicle parts, like the motor, transmission, and brakes, work.
What Fluids Do Electric Vehicles Need?
Electric vehicles don’t need engine oil like regular vehicles but need essential fluids to run correctly.
- Transmission Fluids: Electric vehicles have fewer parts than regular cars, but they still have some mechanical parts, like the transmission. To keep these parts working well, special fluids with the right temperature properties are used. Fubex EV Fluids are made just for electric cars. Transmission fluid doesn’t need to be replaced often—only once or twice during the car’s life.
- Engine Coolant: Coolant helps keep the battery and inverter from getting too hot. You should change the coolant after the car has driven about 49,000 miles.
- Brake Fluid: Even though electric cars use regenerative braking, brake fluid is still essential. It helps the brake pads and disc brakes work correctly, keeping everyone safe. It should be replaced every two years or after about 24,000 miles.
The Role of Lubricants and Fluids in Electric Vehicles
Changing the engine oil and transmission fluid in regular vehicles is essential to keep everything running smoothly. Electric vehicles (EVs) don’t need engine oil or transmission fluid like regular vehicles but need special lubricants to work correctly.
Electric motors spin much faster than regular car engines. A typical gasoline engine might spin up to 6,000 rpm, but an electric motor can go up to 20,000 rpm! Because of this, electric motors need special lubricants to protect their parts from high speeds and changes in power. Lubricants also help improve the motor’s performance.
EVs also need fluids to control their temperature. The battery in an electric car works best when it’s in the proper temperature range. If it’s too cold, the vehicle might charge slowly and not use energy well. The battery could get damaged or be unsafe if it’s too hot.

The Challenges of Lubricating EVs
Electric vehicles (EVs) have a lot of new technology and need special lubricants and fluids to deal with different challenges.
One of the biggest goals for EV drivers is to get the most extended driving range. Special lubricants with extra ingredients help reduce friction between parts, making the vehicles more efficient. All oils and fluids in EVs must also be designed not to interfere with the car’s electrical parts. The lubricants for the motor and reducer also have to work well in really hot or cold temperatures.
As car companies make more complex parts for EVs, the need for better lubricants will grow.
How is Oil for Electric Cars Different from Oil for Regular Cars?
Electric cars are built differently than regular cars with combustion engines, so they need special oil. This means the oil used in electric vehicles has to be made just for them.
Oil for electric cars needs to have these essential features:
- Dielectric properties: This helps keep the oil safe when it touches electrical parts, stopping sparks and short circuits.
- Works with different materials: The oil has to be safe for materials like copper (which carries electricity) and plastic around wires.
- Cooling properties: The oil helps cool down parts by removing heat from the electrical system.
- Protection from wear and damage: The oil protects the car’s parts from getting worn out or rusting.
- Keeps water away: The oil has to stop water from getting to electrical parts to prevent dangerous sparks.
Right now, there aren’t any standard rules for oil in electric cars. Since every electric vehicle is made differently, making one type of oil for all of them is hard. So, oil for electric vehicles is made to fit each car’s specific needs.
The Most Important Lubrication Points in Electric Cars
The transmission in electric cars doesn’t shift gears like in regular cars. It’s usually simple, with only one or two stages. But sometimes, the transmission can go really fast, which puts a lot of stress on the oil. That’s why the oil in electric cars needs to handle high heat and be very strong.
Lubricating greases are used in electric motors, other car parts, and even the central locking system. These greases must work in harsh conditions, like high heat and fast motor speeds, and they must also be safe with copper, plastic, and electrical parts.
A sound cooling system is essential to keeping the car’s batteries working well. Since just using air and water isn’t enough, special cooling liquids are being made to cool the batteries in electric vehicles.
Lubricants in an Electric Vehicle
Even though the gearbox in an electric vehicle (EV) is simpler than in a regular car, it still needs lubrication. EV gearboxes usually don’t have gears that shift like in traditional cars, but they still have moving parts that need to work smoothly and last a long time.
Lubricants must protect against rust and damage. They also need to work well in different temperatures. For example, the battery needs cooling to prevent overheating while charging.
Another important aspect of lubricants is that they should be low-viscosity. This means they help the car use less energy and run more efficiently. They also help the car go further on a single charge, which is really important for EVs!
Bottom Line: Role of Lubricants in Electric Vehicles
In conclusion, even though electric vehicles (EVs) don’t need regular engine oil like gas cars, they still need special lubricants and fluids to keep them running well. These lubricants help protect essential parts like the motor and battery, ensuring everything works smoothly.
They also help calm things down and reduce friction, which allows the car to go farther on a single charge. As more people use electric vehicles, these lubricants will continue to be super important to help EVs perform better and last longer.
FAQs
Q1: Which lubricant is used in electric vehicles?
Electric vehicles use special lubricants made from synthetic oils. These oils work better than regular oils because they can handle high temperatures and keep the vehicles running smoothly.
Q2: What does lubricating oil do in a vehicle?
Lubricating oil helps prevent the engine parts from rubbing against each other. This reduces wear and tear on the engine and helps keep it cool by preventing it from getting too hot.
