THERMAL & OXIDATION STABILITY
Fluid oxidation is a chemical reaction between the fluid and oxygen. It can be responsible for viscosity increase, varnish formation, sludge and sediment formation, additive depletion, base oil breakdown, filter plugging, loss in anti-foam properties, acid number increase, as well as rust and corrosion. Controlling oxidation is a significant challenge in trying to extend the lubricants life. Royal Oil Co. uses new generation base oils that are more oxidation stable and a much greater quantity of powerful anti-oxidation chemistry than is necessary to pass equipment manufacturers test. As a result, ULTRA TORQUE handles high temperatures and provides severe oxidation protection. Testing procedures for the Allison specification requires a minimum 320 °F flash point.
ULTRA TORQUE has a typical flashpoint of 485 °F, providing a much higher degree of protection against high temperatures and oxidation.
