Red Line Synthetic Motorcycle Oil

The synthetic base stocks used by Red Line have a natural multigrade property so they do not require large amounts of unstable polymeric thickeners as used in multigrade petroleum oils. The superior high-temperature stability makes these oils ideal for use in turbocharged and air-cooled four-stroke applications. Red Line oils also feature more ZDDP than other street oils, which makes them ideal for use in solid-lifter and flat-tappet engines. Red Line Motorcycle Oils are blended with friction modifiers specifically for wet-clutch applications. For normal street use, Red Line recommends oil changes every 12-18,000 miles for gasoline engines, or at least once per year.
