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. It increases cetane number of any diesel fuel for quicker, smoother, quieter, more complete combustion. It burns up to 42% cleaner exhaust emissions when measured by the opacity method. It keeps injectors clean and cleans up dirty injectors. It reduces injector & injector pump wear caused by today's abrasive low sulfur fuels. Improves cold weather performance, lowers cold start temperatures & reduces warm-up time and reduces smoking, misfiring, & knocking.
