  • Most concentrated Red Line diesel product
  • Cleans and lubricates injectors, pumps, and rings
  • Improves efficiency up to 5%
  • Provides the detergency, lubrication, and faster combustion today's diesel fuels need
  • Complies with federal low-sulfur content requirements
  • Formulated for both summer and winter — pour-point reducers keep wax in suspension and reduce wax crystals to pass through filters and injectors
