Castrol Launches First Dedicated EV Transmission Fluids for Workshops
  • First time in Europe that Castrol ON products are available in the aftersales sector
  • Launch of Castrol ON EV Transmission Fluids D1 and D2 – suitable for many EVs with dry motors
  • All Castrol ON products are certified carbon neutral1 as part of Castrol’s sustainability strategy PATH360

Castrol has launched Castrol ON EV Transmission Fluids specifically for use by franchised and independent workshops certified to work on electrified vehicle (EV) powertrains. Available in five-litre packs, the two new products – in D1 and D2 variants – suit a wide range of EVs, helping to extend the life of the drivetrain system and enable EVs to go further2 on a single charge.

The new product is a high performance and high efficiency fully synthetic fluid for transmissions paired with dry e-motors, offering high levels of gear and bearing protection.
Castrol ON EV Transmission Fluid is part of a broader family of advanced Castrol ON EV fluids. The range includes EV Transmission Fluids, EV Thermal Fluids and EV Greases that help with the mainstream adoption of EVs by helping EVs go further2, charge faster3 and last longer4.


  •  Advanced EV Transmission Fluids deliver enhanced protection of the drivetrain and improve efficiency5
  • Castrol EV Thermal Fluids help keep batteries cooler, even in extreme conditions, and this enables ultra-fast charging (>150kw)
  • EV Greases play a vital role in maintaining optimum efficiency and extending the life of vehicle components.


Two out of three of the world’s major car manufacturers now choose Castrol ON for their factory fill6.
“As greater volumes of electric vehicles enter the aftermarket, more OEMs have asked us to make an advanced EV transmission fluid available to their workshop partners, to support ongoing repair and maintenance activity,” comments Patrick Bauer – Castrol Senior Technologist PD Driveline & EV Fluids. “While these fluids in some EVs are deemed ‘fill for life’, workshops need replacement product in the event of a repair, and there can also be a requirement to change the product early to safeguard protection in certain use cases.
“We have collaborated very closely with OEMs and Tier One suppliers to develop, test and deploy products to meet the required performance criteria,” Patrick Bauer concludes.
In addition to supporting businesses bringing production EVs to market, Castrol has worked with the Jaguar TCS Racing Formula E Team. This means that EV fluid technologies can be pushed and tested on the track before they reach the road.
Castrol aims to be a net zero brand by 2050 or sooner. Castrol ON EV fluids are certified carbon neutral¹.
The launch of Castrol ON products is aligned with the company’s PATH360 strategy, which aims to help deliver a more sustainable future by saving waste, reducing carbon and improving lives. Castrol is investing in and developing products that support the world’s transition to renewable energy and the wider adoption of e-mobility.
