ZEP Diesel Fuel Additive, 5 Gallon, 1 Pail

Blend of solvents, emulsifiers, lubricants, and corrosion inhibitors that dissolves and removes sludge and fuel deposits from storage tanks, fuel lines, pumps, filters, and burners. Solubilizes the heavy oils and waxes that form sludge and deposits. Will not interfere with oil/water separators. Pour-point depressants keep fuel free-flowing in cold weather. Cetane improver prevents spitting and sputtering at the burner and allows fuel to burn more evenly in the combustion chamber for reduced knock and clatter.
