High quality diesel to get you where you’re going.

Our diesel fuels are blended to provide good ignition quality and are held to high quality standards for our consumers. Their low-temperature fluidity characteristics can also help keep vehicles moving in colder temperatures. Our Ultra Low Sulfur Diesel Fuel is made to meet the needs of the most demanding customers. This diesel fuel is formulated for use in any diesel-fueled vehicle on the road today.

Diesel is different from gasoline

Diesel and gasoline are both derived from crude oil, they work similarly, but are not interchangeable. Both fuels are normally injected under high temperature and pressure, however, diesel ignites by the high pressure and temperature while gasoline ignition is set by the spark plug.

Diesel engines sometimes emit smoke

Diesel engine smoke is caused by incomplete combustion. White smoke is caused by tiny droplets of unburned fuel resulting from engine misfiring at low temperature. This smoke should disappear as the engine warms up. Black smoke could be caused by a faulty injector, insufficient air or overloading and/or over-fueling the engine. Blue-gray smoke is the result of burning lubricating oil and is an indication the engine is in poor mechanical condition.

Less energy, better fuel economy

Diesel fuel requires less energy to produce than gasoline. Because diesel has a higher energy density it provides better fuel economy compared to gasoline.

Diesel is adjusted for cold temperatures

Exxon and Mobil service stations offer winterized products in the majority of regions that commonly experience temperatures below 10°F.


If you keep it clean, cool and dry, diesel fuel can be stored 6 months without significant quality degradation. Storing diesel for longer periods of time can be accomplished by using periodic filtrations and adding fuel stabilizers and biocides.
