Red Line Transmission Oil

Transmissions, both manual and automatic, and final drives are lubricating oil areas that rarely or never receive any maintenance. Unfortunately are the service intervals in principle completely eliminated from the manufacturers except for taxis application.

Generally, all oils age/wear, detritus and condensate adds to the oil and many oils also lose their viscosity properties. This leads to undesirable wear, higher fuel consumption and lower switching function.

Red Line Oil provides oil for all types of transmissions. All products are fully synthetic and based on the same idea; to provide the best possible protection and functionality for a long and car ownership.

Red Line oils often provide a noticeable improvement in shift quality in all conditions.

The oil has a very stable viscosity over a wide temperature range, and provides an oil film that is stronger than the corresponding mineral and synthetic oils with other base oil.

The oil has a very high adhesion to metal, which prevents water to come in contact with the metal and completely prevents the formation of corrosion. The high adhesion combined with a really strong oil film reduces wear while efficiency is improved.

The oils very high stability prevents the formation of waste products, which is a common problem with mineral oils. Small amount of waste products prevents wear on the gears, chain, and seals.
