They reduce friction so well that gears run cooler and last longer. They reduce drag so effectively they actually improve fuel economy in most applications. They virtually eliminate spark plug fouling and deposit build-up in the engine while reducing exhaust emissions. They are made with synthetic base oils and lithium complex thickeners, and provide outstanding film strength, shear resistance and stability. The fuels available today are not of consistent quality and often don't deliver optimum performance in the equipment they're used in.
Incomplete ignition can occur, leading to varnish and carbon buildup.
Fuels can also contain materials that act as contaminants, fouling fuel and combustion systems as they burn. This leads to equipment performance problems, excessive exhaust emissions, and decreased fuel economy. Copyright 1999 Automotive Marketing Services - All rights are reserved.
