Fuel and Lubricant Solutions



When lubricants are exposed to heat, gases or mechanical stress, the molecules can break down and form radicals which react with oxygen to cause oil thickening, deposits and acid build-up. 

Antioxidants extend the useful life of lubricants by eliminating these radicals and preventing thermo-oxidative breakdown.

Lubricants formulated without antioxidants may have to be replaced after a short time due to degradation as shown in the above picture. Our core competency in antioxidants has set the standard for lubricant oxidative stability.
