Opti-Lube provides exceptional lubrication in the fuel system, helping overcome the loss in lubricity with the introduction of Ultra Low Sulfur Diesel (ULSD). It helps the fuel burn more completely, reducing harmful deposits. It also shows a 35% wear reduction in the ASTM D-5001 Wear Test. Opti-Lube Winter Formula is specifically designed to stop fuel waxing and gelling in extreme cold, and also improves stability of ULSD during storage.
1 Quart container. Add 2-3 oz. to each 10 gallons of diesel fuel.
