Castrol ON EV Transmission Fluid W2 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 Transmission
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.
