85 Plus! Winterized Formula

This product can expose you to chemicals including Naphthalene (91-20-3) which is known to the State of California to cause cancer. For more information go to www.P65Warnings.ca.gov.

Available in different levels of concentration, these products provide the detergency, lubrication, and faster combustion for today's diesel fuels

  • All Red Line Diesel additives comply with federal low-sulfur content requirements
  • Rather than creating new products in the diesel category, Red Line reformulates these products often to ensure that they meet the changing demands of the latest diesel fuels
  • Winter formulas use pour-point reducers to keep wax in suspension and reduce wax crystals to pass through filters and injectors
