RED LINE 85 PLUS is designed to improve fuel combustion and prolong the life of the fuel system. Red Line 85 Plus contains powerful thermally-stable detergents which clean fuel injectors and the compression ring area which can become filled with partially-burned combustion products. Lubricity additives lubricate fuel pumps and injectors and leave a coating in the upper cylinder, reducing friction at the critical point where the rings change direction - providing increased power. A octane booster is incorporated which will improve cold weather starting and reduce knocking and smoke.
