AMSOIL has formulated a new diesel fuel additive that not only cleans and lubricates your fuel system, but it also improves the “cold filter-plugging point” in winter weather. The new AMSOIL Diesel Concentrate Plus Cold Flow Improver enhances performance and fuel economy by keeping the fuel system clean. When your fuel system is “deposit-free”, your fuel economy is optimized. The net savings on fuel pays for this product, so the effects of a clean fuel system and the reduced risk of wax crystals clogging the fuel filter are essentially free. This product also improves the lubricity lost in modern Ultra Low Sulfur Diesel (ULSD) fuels.
