Bardahl 1 polar attraction effect is achieved thanks to the ideal balance of anti-wear, anti-friction, anti-oxidative and detergent additives and polar organic compounds comprised in the Bardahl 1. The additive forms a resistant molecular film on all rubbing metal surfaces of engine parts and can sustain critical mechanical and temperature loads. It prevents formation of deposits, reduces engine wear at the engine cold start and during all the operation period between oil changes which allows you to significantly increase reliability and efficiency of the lubrication system and the whole engine and, as a result, increase the repair intervals. It reduces friction and decreases fuel consumption and operational costs. It does not change the viscosity grade of the motor oil.
