Advanced EV Fluids to protect your EV’s transmission, and extend the life of the drivetrain system.

Transmission EV Fluids

Advanced transmission ev fluids for dry and wet e- motors

 

Electric car transmissions

Unlike cars with combustion engines, which require a multi-speed transmission, the e-motor in an electric vehicle produces a consistent amount of torque, almost regardless of RPM. As a result, the majority of EVs feature a much simpler single-speed transmission, with an option for neutral and reverse gears too.  That being said, it’s likely that – as the market’s offering of EV technology evolves – electric cars with multi-speed transmissions will become more widely available.
 
It’s important to note that the role of transmission fluid is even more vital in an EV. That’s because the demands on EV transmissions are more severe than conventional transmissions, with maximum torque delivered at low speeds and the increasing integration of electric motors. Electric vehicles can either use a separate electric motor and EV transmission (dry e-motor), or a combined system (wet e-motor) demanding more from the EV fluid.

 

Castrol ON EV Transmission Fluids range includes fluids for dry and wet e-motors.​ Please reach out to your local Distributor to check availability in your market for after sales.

Dry Transmission

Dry transmission EV fluid

 

The challenge

EV transmissions can experience extremely high torque at low speeds and at the same time have to deal with more than double input speeds from the electric motor putting the fluid under immense stress. In addition, the limited range and resulting range anxiety need to be overcome.

 

Our technology

Castrol ON dry EV transmission fluid resists the effects of working hard, providing enhanced protection, reduced viscosity loss and fast release of entrained air whilst enabling maximum efficiency.

 

The result

Helps extend the life of the drivetrain system and help EVs go further1* on a single charge.

Castrol ON EV Dry transmission fluid D1

Availability

For vehicle manufacturers, distributors, and workshops.

Castrol ON EV Dry transmission fluid D2

Availability

For vehicle manufacturers, distributors, workshops, and owners of electric vehicles.

Wet Transmission

Wet transmission EV fluid

 

The challenge

EV motors can experience extremely high torque at low speeds.  The transmission element has to deal with more than double input speeds from the motor and the motor unit operates immersed in the transmission fluid. 

 

Our technology

Castrol wet transmission EV fluid’s low viscosity formulation is specifically developed to deliver low electrical conductivity, enhanced system protection and helps the e-motor run cooler enabling it to operate at high efficiency.

 

The result

Helps extend the life of the drivetrain system and help EVs go further1* on a single charge.

Castrol ON Wet transmission W2

Availability

For vehicle manufacturers, distributors, and workshops.

Castrol ON Wet transmission W5

Availability

For vehicle manufacturers, distributors, and workshops.

Wet Plus Transmission

Wet plus transmission EV fluid

 

The challenge

Future EV motor-transmissions can be enhanced by adding a shifting device to reach higher speeds, operate with synchroniser systems at high speeds and loads and to enable the e-Motor to drive in the most efficient range.

 

Our technology

Castrol wet plus transmission EV fluid’s specially-developed technology, with its optimised friction levels for synchroniser systems and clutches, allows efficient shifting under high loads and speeds and to operate the e-motor in the most efficient range.

 

The result

Helps extend the life of the drivetrain system and help EVs go further1* on a single charge.
