SWEPCO 501 Premium Diesel Fuel Improver is a highly effective multi-function diesel fuel improver which improves the combustion characteristics of today’s low quality diesel fuels and prevents formation of sludge, varnish and gum deposits which slowly rob diesel engines of performance. SWEPCO 501’s unique formulation delivers quicker, cleaner, more complete combustion by increasing cetane numbers of today’s fuels. At the same time it fights the most common problems associated with diesel fuel . . . sludging, oxidation, corrosion, icing and the abrasive effects of ultra low sulfur fuel. The result is cleaner engines and fuel systems, longer injector and injector pump life, better performance, lower emission levels, lower maintenance costs and improved fuel economy.
Description & Purpose SWEPCO 501 Premium Diesel Fuel Improver is a highly effective multi-function diesel fuel additive. Besides improving lubricity and controlling combustion deposits, it increases the cetane number of any diesel fuel. Increased cetane numbers result in improved combustion, lower emission levels and better cold weather operability. A special Winter Formula also provides protection from cold weather diesel fuel gelling problems.
