Transmission EV Fluids
Advanced EV Fluids to protect your EV’s transmission, and extend the life of the drivetrain system.
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 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.
Availability
For vehicle manufacturers, distributors, and workshops.
Availability
For vehicle manufacturers, distributors, workshops, and owners of electric vehicles.
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.

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.
