Castrol ON EV Transmission Fluids
Our Castrol ON EV Transmission Fluids help reduce vibration and energy losses, improve efficiency and extend drivetrain system life.
Engineered to advance performance
The EV conversation is evolving rapidly. We are listening closely to our customers, and our global research shows that as the market matures, the focus is shifting away from early pain points toward the positive, emotional benefits of electric mobility. Drivers increasingly value refinement, comfort, and the overall driving experience EVs deliver.
In response, we have developed a new offering that helps OEMs deliver on these expectations. Our Castrol ON EV Transmission Fluid reduces noise, vibration, and harshness – while increasing efficiency and extending the life of the drivetrain. Helping EVs to:
Drive quieter1

Co-engineered with OEMs, enhancing what EV drivers love most
Castrol ON EV Transmission Fluid helps reduce noise, reduce vibration, and reduce harshness in the drivetrain – whilst increasing efficiency.
Why choose Castrol ON EV Transmission Fluids
Castrol ON EV Transmission Fluids offer protective solutions for both dry and wet e-motors. Contact your local distributor for availability in your market.
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 Transmission EV Fluid technology
Castrol ON Dry EV Transmission Fluid resists the effects of working at peak intensity. Providing enhanced protection, reduced viscosity loss and fast release of entrained air whilst enabling maximum efficiency.
Castrol ON Dry EV Transmission Fluid
Helps extend the life of the drivetrain system and helps EVs drive quieter1, go further and last longer2.
Castrol ON: EV Dry Transmission Fluid
Explore our high performance and high efficiency full synthetic fluids for transmissions with dry e-Motors.
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 Transmission EV Fluid technology
Castrol ON Wet EV Transmission 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.
Castrol ON Wet EV Transmission Fluid
Helps extend the life of the drivetrain system and helps EVs drive quieter1, go further and last longer2.
Castrol ON: EV Wet Transmission Fluid
Explore our high performance and high efficiency full synthetic fluid* for transmissions with wet e-Motors.
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 Transmission EV Fluid technology
Castrol ON Wet Plus EV Transmission Fluid is 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.
