We stand first when it comes to offering quality DNR Hydgear Series (gear oil). This is basically a type of motor oil made specifically for the purpose of transmissions and differentials in automobiles, trucks, and other machinery. It is of a higher viscosity that enables protection of gears. Usually associated with a strong sulfur smell, the heavy oil is associated with parts that move somewhat slower and which are far away from the combustion in the engine. Our DNR Hydgear Series (Gear Oil) is available in various specifications such as ep 90 gear oil and ep 140 gear oil.
