Shell Oil Products U.S. announced a test of Shell Nitrogen Enriched Diesel, extending the company's exclusive "Nitrogen Enriched" advanced cleaning system to diesel.


The fuel has been proven to reduce fuel consumption in an extensive test of heavy-duty vehicles and is now available on a trial basis. It will be offered to commercial as well as retail customers at select points of sale in the Nashville, Tenn., Baltimore, and Richmond, Norfolk and Virginia Beach, Va.., areas.

Shell Nitrogen Enriched Diesel will be available only to commercial customers in the Atlanta area.

Shell Nitrogen Enriched Diesel is an ultra low sulfur diesel fuel with an advanced cleaning system that helps protect diesel engines against performance-robbing gunk build-up on fuel injectors with continual use. Gunk build-up can impair optimal fuel flow and can result in increased fuel consumption and associated CO2 emissions.

Shell Nitrogen Enriched Diesel also guards against corrosion. Like the Shell-branded ULSD in the market today, Shell Nitrogen Enriched Diesel contains lubricity agents to help prevent fuel pump and injector wear and damage. Anti-gel agents for colder winter climates will also be available where needed.

Extensive heavy-duty truck fleet trials of Shell Nitrogen Enriched Diesel demonstrated a 4.8 percent reduction in fuel consumption in more severe stop-and-go city service and a 1.3 percent reduction in fuel consumption in less severe long-haul highway service as compared to regular ULSD.
