75 ml bottle of silicone oil for 15.000cst differentials from Ultimate Racing. The differential oil from Ultimate Racing is made with 100% pure silicone to provide stable performance at any operating temperature, delaying differential fatigue. The silicone gradation is measured in Cst, and the higher the article number, the denser it is. It also contains anti-friction additives that minimize friction and thus wear on the differential gears.
