XTREME GEAR OILS are full synthetic, premium quality, commercial drive-train lubricants designed for extended drain interval service and to meet the rigorous demands of off warranty vehicles. XTREME GEAR OILS provide outstanding performance in heavy duty drive-trains where extreme pressure and shock loading are common. XTREME FULL SYNTHETIC GEAR OILS offer enhanced friction reduction properties, exceptional shear stability, and limited slip protection designed for full service-fill change out in high-performance vehicles, passenger car and light-duty truck applications.


XTREME GEAR OILS are designed for heavy-duty manual transmissions, axles and final drives requiring API GL-5 and MT-1 performance. Applications include off-highway vehicles, light and heavy-duty trucks, busses and vans, hypoid and worm gears operating under conditions where high speed/high torque conditions prevail.  Use for heavy duty vehicles where warranty and OEM approvals are not a consideration.  While XTREME GEAR OILS are specifically designed for HD applications, they are perfectly suitable for high performance vehicle, passenger car and light-duty applications with and without limited slip differentials.


XTREME DIFFERENTIAL GEAR OILS offer exceptional component protection using fully synthetic base stocks and robust long-drain performance additives. These fluids are designed to withstand up to 500,000 miles of severe service under proper operating conditions in both on and off-road applications to maximize productivity*. XTREME DIFFERENTIAL GEAR OILS offer superior thermal stability and resistance to high-temperature oxidation, outstanding protection against low-speed/high-torque wear and high-speed scoring, and excellent low-temperature fluidity versus mineral oils.
