Ultra-15 Hydraulic Steering Fluid
HyDrive hydraulic steering systems are manufactured to much tighter tolerences than other brands and as such require superior steering fluid. ULTRA-15 is made from Hydraulic Piston Oil, not the Hydraulic Gear Oil found elsewhere. HyDrive Steering Fluid also contains a number of additives including moisture inhibitors which assist to maximise your HyDrive steering system life. Only for use with HyDrive steering systems. Other manufacturers oils are not the same - do not mix products.
