Manufacturers of heavy-duty vehicles are required to make and market vehicles that meet certain fuel economy standards. So it only makes good business sense to maintain that fuel economy throughout the life of the vehicle.
Over time, deposits develop in the combustion chamber, debris accumulates in the fuel system, injectors clog, and fuel system delivery systems degrade. All of these conditions negatively affect fuel economy and performance, and proper maintenance can prevent or correct such issues.
Central to achieving and maintaining high levels of fuel efficiency are fuel additives that clean diesel fuel systems and fortify diesel fuels, including bio-fuels. Several such additives are offered by Penray Inc., a leader in the blending and manufacture of fuel additives and functional fluids for the light-to-heavy duty truck market.
