Car axle lubricant has always played an essential part in maintaining reliability and longevity. But rear axle fluids are more important than ever, in an era of heavier cars with more complex transmissions and differentials.

Castrol is the axle oil of choice for many leading car and transmission manufacturers, ensuring that when you choose Castrol axle lubricant, your rear axle will perform as the manufacturer intended, reducing the chance of handling issues or expensive repairs.

Always consult your car’s handbook to make sure you find the correct fluid for your transmission.
