Full synthetic Caterpillar FD-1 type lubricant that extends drain intervals and improves gear and bearing life in final drives and axles.

• Meets the performance attributes of synthetic fluids for Caterpillar final drives and axles
• Protects gears and bearings against wear in severe duty applications
• Improves extreme-pressure (EP) performance when compared to TO-4 fluids
• Delivers enhanced low-temperature performance compared to conventional CAT final drive and axle fluids
• Proven to demonstrate extended drain intervals of up to 6,000 hours for off-highway trucks' final drive and rear axles compared to the typical 2,000-hour drain interval recommended for TO-4 fluids^[1]
• Not for use in compartments containing friction material unless an FD-1-type product is specified
