Military Gearboxes

 A major military gearbox manufacturer has tested Cool-X in a prototype differential for the JLTV program. Adding the Cool-X ATF lowered temperatures in the differential by 15°F in synthetic oil and 29°F in mineral oil. In fact, both oils were lowered to the same operating temperature.

The advantages of lower oil temperature include significantly longer oil life (an industry rule of thumb is that every 18°F doubles oil life) and enhanced antiwear characteristics. The burnishing effects of Cool-X include wear hardening of the gear surfaces, burnishing of the gears (keeping them polished and clean), and preventing pitting and corrosion.

Further military testing is expected.
