Howes Winter Treat Plus Anti-Gel comes in 2 1/2 gallon containers and is the best weather protection available. It lubricates fuel systems and can lower the Cold Filter Plugging Point by up to 20 degrees or more. It will increase fuel economy by reducing the requirement for blended fuel, which has a lower BTU content. The fuel filter life will be prolonged because contaminants will be reduced and water will be safely controlled. The Winter Treat Plus contains a Wax Crystal Modifier to reduce the size and alter the shape of wax crystals as they precipitate from the diesel fuel in lower temperatures. This reduces the incidences of vehicle failures during the cold weather. Call us if you are seeking 6+ cases.
