Adds Up To 2.5x More Lubricity - With more lubricity than any other Howes product and many on the market, Diesel Defender is the ultimate choice for heavy duty vehicles. It provides protection by significantly reducing wear scars, with independent lab* results confirming Defender treated fuel outperformed the US (520mm) and more stringent European (460mm) standards. *via the wear scar test for ASTM D975 High Frequency Reciprocating Rig (HFRR)
Cleans Fuel Injectors - Uses superior IDX4 Detergent to attack and destroy even the toughest carbon deposits. When used as directed, Diesel Defender is designed to clean the entire fuel system within three treatments and prevent future deposits from forming. The removal of these deposits keeps the diesel fuel system performing optimally and increases power.
Increased Fuel Economy Guaranteed - By safely removing water, Diesel Defender leaves only pure fuel to burn. Your clean injectors then allow for a steady spray pattern, so none of that fuel is wasted. When used regularly, Diesel Defender guarantees a minimum 5% increase in fuel economy.
Removes Water - Many products emulsify or disperse water and frequently use alcohols or solvents that can do damage to your engine. Diesel Defender is a premium, petroleum based product that demulsifies water, safely removing it from diesel fuel.
