Whether you're hauling across cities or continents, trust in a fluid that helps your electric fleet go further1* on a single charge.

 

Switch ON an electric future

Why choose Castrol ON EV Transmission Fluids for electric trucks?

Castrol ON EV Transmission Fluids provide advanced protective solutions for both dry and wet e-motors. Dry EV Transmission Fluids operate outside of electrical components, while Wet EV Transmission Fluids directly contact and cool electrified parts. 

 

By protecting gears and other critical drivetrain components, Castrol ON EV Transmission Fluids help improve transmission efficiency, enhance reliability, and extend the overall lifespan of the system - delivering performance solutions tailored to the unique demands of modern electric trucks.

 

Dry EV Transmission Fluids

Designed for gearboxes with no direct cooling contact to eMotor, Dry EV Transmission Fluids provide:

  • Optimised viscosity for improved energy efficiency and reduced drag losses also to ensure hardware protection for truck applications.
  • Excellent thermal and oxidative stability, supporting long service intervals even under high thermal loads.

 

Wet EV Transmission Fluids

Formulated for systems where the fluid has dual role and directly cools electric motor and lubricates gearbox, Wet EV Transmission Fluids offer:

  • Enhanced thermal conductivity for direct cooling of stators and rotors.
  • Dielectric properties tailored to maintain safe operation.
  • Material compatibility with copper, and polymer insulation systems.
