As trucks and buses become heavier and the need for durability increases, axle fluids are more and more critical for vehicle reliability. Getting the right oil for your vehicle is key to ensuring your rear axle operates as designed and gets the maximum protection under demanding conditions.
Castrol, with over 100 years of experience in developing axle fluids, and being the choice of many leading truck and transmissions manufacturers for factory-fill products, offers a range of axle and universal fluids for your vehicle requirements; providing you the peace of mind that you are getting the right oil for your vehicle and keeping your vehicle on the road longer.
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.
