The Terrain CT range is formulated with high quality mineral oils and additives designed to provide the correct frictional characteristics required by Caterpillar in transmission and hydraulic systems. The additive system also gives this oil improved temperature performance, superior resistance to oxidation, rust, corrosion and improved anti-foam properties. In addition these grades have excellent extreme pressure (EP) and anti-wear characteristics ensuring maximum frictional material life in powershift transmissions. Terrain CT grades also have outstanding wet brake performance, eliminating "squawk and chatter" and prolonging component life.
