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.
