Electric Vehicle Lubricants

The growth of electric vehicles is changing how lubricants are used in the automotive sector. While electric vehicles do not use traditional engine oil, they still rely on specialised fluids and lubricants to operate reliably.

As EV adoption increases, lubricant demand is shifting rather than disappearing.

No engine oil

Electric vehicles do not have internal combustion engines, so they do not require engine oil. This removes one of the largest traditional lubricant uses in passenger vehicles.

However, this does not mean electric vehicles are lubricant free.

Gearboxes and drivetrains

Most electric vehicles use reduction gearboxes to transfer power from the electric motor to the wheels. These gearboxes require lubricants designed to handle high torque and continuous operation.

Lubricants must also be compatible with electric motor components and materials.

Thermal management fluids

Electric vehicles rely heavily on temperature control. Batteries, motors, and power electronics all generate heat and require effective cooling.

Specialised thermal management fluids are used to maintain safe operating temperatures and protect system components.

Noise and efficiency demands

Electric vehicles operate more quietly than combustion engines, making noise from gearboxes and drivetrains more noticeable.

Lubricants must help reduce noise while maintaining efficiency and component protection.

Why this matters

As electric vehicles become more common, lubricant technology is adapting to new requirements rather than becoming obsolete.

Understanding how lubrication supports electric vehicles helps explain how the lubricant industry is evolving alongside changes in vehicle technology.
