MDE, delivered by ExxonMobil authorized resellers, is the first and only fully formulated, additized diesel fuel with a proven fuel economy claim in the United States. It is specially engineered to help improve fuel economy and boost engine performance by cleaning up injector deposits. This new fuel also helps improve power, increase engine responsiveness and reduce emissions. MDE fuel can also help guard against internal injector sticking which can contribute to premature injector failure. Furthermore, MDE fuel offers excellent fuel system corrosion protection and can help prevent premature fuel filter plugging.
