Enhance the quality and efficiency of fuel in motor vehicles by adding automotive additives from Grainger. Exposure to extreme temperatures can lead to oil breakdown. Oil additives help reduce and prevent valve-sticking by removing harmful sludge and carbon deposits. Adding additives to fuel can improve mileage by reducing deposits on injectors and engine carburetor jets. Transmission additives can help restore smooth shifting and extend transmission life.
