Low sulfur diesel fuels have become environmental necessity. The reduction in the sulfur content of diesel fuels has resulted in lubricity problems.

It has become generally accepted that the reduction of sulfur is also accompanied by a reduction in polar oxygenated compounds and polycyclic aromatics including nitrogen containing compounds which are responsible for the reduced boundary lubricating ability of severely refined  low sulfur fuels.

Low sulfur diesel fuels  have been found to increase the sliding adhesive wear and fretting wear of pump components such as rovers, cam plate, coupling lever joints and shafts drive journal bearings.

Thus, it would be desirable to increase the lubricity of diesel fuels by incorporating lubricity additives.

The product is designed and formulated for blending with low sulfur diesel fuels to improve lubricity and to preserve abnormal wear in the engine fuel pumps.

Composition :
The product is a blend of organic esters and acids with anti-corrosion and detergent/dispersant additives.
