Mobil Diesel Efficient

Mobil Diesel Efficient fuel helps improve fuel system performance in both on- and off-highway applications. The advanced fuel has been engineered to improve diesel fuel economy and boost engine performance, and has been tested in multiple real-world applications.

Mobil Diesel Efficient Fuel is available at our Fuel Sites - Summit, Chicago, Bensenville, Channahon, Hammond

Features and Benefits

Mobil Diesel Efficient fuel contains a patented additive technology that is specially designed to clean up both internal injector

deposits and nozzle coking deposits. Today’s diesel engines have sophisticated fuel systems engineered to meet stringent emissions requirements. Deposits that form inside the fuel injectors can impede the movement of the needle, and cause early failure of the injectors. Deposits building up inside the injector nozzle can restrict fuel flow, deteriorate the fuel spray quality and result in loss of engine power, increased emissions and reduced fuel economy. Mobil Diesel Efficient fuel helps to prevent deposit formation and clean up existing deposits that may be damaging your engine performance.

We offer both On & Off-Road Ultra Low Sulfur Diesel.

Developed to allow the use of improved pollution control devices that reduce diesel emissions more effectively but can be damaged by sulfur, ULSD is a cleaner burning diesel fuel that contains 97% less sulfur than low-sulfur diesel. Companies with 2007 or later model year diesel vehicles should only fuel them with ULSD. ULSD has a maximum sulfur content of 15 parts per million (ppm).

E-85 / Flex Fuel

Flexible fuel vehicles (FFVs) are designed to run on gasoline or a blend of up to 85% ethanol (E85). Except for a few engine and fuel system modifications, they are identical to gasoline-only models. FFVs experience no loss in performance when operating on E85. However, since ethanol contains less energy per volume than gasoline, FFVs typically get about 25-30% fewer miles per gallon when fueled with E85. *Check with your fuel system and fuel container manufacturers for compatibility with ethanol and E85 blends.

Biodiesel is a form of diesel fuel manufactured from vegetable oils, animal fats, or recycled restaurant greases. It is safe, biodegradable, and produces less air pollutants than petroleum-based diesel. Biodiesel can be used in its pure form (B100) or blended with petroleum diesel. Al Warren Oil Company offers all available blends. More information provided by the National Biodiesel Board: www.biodiesel.org
