Castrol EV Fluids

Motorists trust Castrol on EV transmission thanks to the company's reputation for innovation and performance. These products contain a thermal management system that can extend the life of the drivetrain system and other key components, deliver maximum efficiency to improve battery life, and deliver the highest levels of performance for electric vehicles.

Whether used for OEM-level filling, workshop servicing or electric fleet maintenance, Castrol’s EV-specific technologies deliver essential efficiency for electric cars and other vehicles operating in demanding UK urban, rural and commercial environments. Castrol promises that its fluids deliver better EV running and charging than mass market EV factory fill fluids or standard EV transmission fluid, with several performance benefits demonstrated in bespoke testing and development processes.

These fluids play a crucial role in controlling battery and inverter temperatures, which supports ultra-fast charging cycles, extending component life and reducing energy losses across the drivetrain. Their formulation focuses on dielectric strength, rapid heat transfer, low viscosity for improved efficiency and material compatibility with advanced polymers and copper windings commonly found in EV architectures.
