As cars become heavier and the need for durability increases, rear axle fluids are more and more critical for vehicle reliability. Getting the right oil for your car is key to ensuring your rear axle operates as designed and you get a smooth driving experience every day.
Castrol, with over 100 years of experience in developing axle fluids, and being the choice of many leading car and transmissions manufacturers for factory-fill products, offers a range of axle and universal fluids for your car’s requirements. Providing you the peace of mind that you are selecting the right oil for your vehicle.
As part of a global simplification program, Castrol’s entire driveline range is now unified under the Castrol TRANSMAX brand.The advanced Castrol TRANSMAX range features Smooth Drive Technology™ with active control molecules that automatically adjust their friction level with changing pressures and speed. This ensures the transmission is constantly served the right level of friction at any given moment – protecting the parts and delivering a smoother drive for longer. That’s why, 2 out of every 3 major vehicle manufacturers** choose Castrol transmission fluids as part of their factory fill.
