Castrol ON EV Transmission Fluid W5 is a full synthetic, high performance, high efficiency fluid for transmissions with
wet e-Motors, i.e., where the e-motor operates immersed in the EV Fluid. It is an advanced EV Transmission Fluid that
helps extend the life of the drivetrain system and go further¹ on a single charge. This next generation transmission fluid
has specially developed, low viscosity technology that delivers low electrical conductivity, enhanced system protection
and helps the e-motor run cooler enabling it to operate at high efficiency.

Outstanding di-electrical properties:
low conductivity
high resistance
high breakdown voltage
1.
2. Very good copper corrosion protection
3. Excellent pumpability at low operating temperatures
4. Exceptional cold flow properties
5. Excellent thermal and oxidative stability
6. Exceptional temperature reduction through reduced friction
7. Excellent gear protection
8. Excellent thermal properties
