This Red Line two-cycle racing oil provides improved power and perfect cleanliness. Power improvements of 3 to 5 percent have been obtained in dyno tests. Its high-temperature stability prevents deposits in even the hottest upper ring and piston crown areas. Two-cycle racing oil is suggested for use at 50:1, but can be used richer or leaner, up to 100:1, depending on the type of engine and its operating conditions. It provides unequalled protection in motorcycles and marine engines as premix or injection oil.
