Shell Oil Products US announced a test of Shell Nitrogen Enriched Diesel, extending the company’s “Nitrogen Enriched” advanced cleaning system to diesel. The company says the fuel has been proven to reduce fuel consumption in an extensive test of heavy-duty vehicles and now is available on a trial basis. It will be offered to both commercial as well as retail customers at select points of sale in the areas of Baltimore; Nashville, Tenn.; and Richmond, Norfolk and Virginia Beach, Va. 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 (ULSD) with an advanced cleaning system formulated to help protect a diesel engine against performance-robbing gunk buildup on fuel injectors with continual use. Gunk buildup can impair optimal fuel flow and can result in increased fuel consumption and associated CO2 emissions.

Shell Nitrogen Enriched Diesel also is formulated to guard against corrosion with lubricity agents to help prevent fuel pump and injector wear and damage. Anti-gel agents for colder winter climates also will be available where needed. And according to the company, 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.

“We are very excited about this latest opportunity to test an advanced ultra-low-sulfur diesel fuel,” says Jim Macias, a senior fuels technology manager for Shell. “It is well-suited for the evolving cleaner-burning diesel fuel market demand because Shell Nitrogen Enriched Diesel is designed for use in both traditional as well as new ultra-clean diesel engines with advanced emission controls. Additionally, the exclusive ‘Nitrogen Enriched’ advanced cleaning system is also fully compatible with biodiesel blends, which positions Shell to supply a high-quality product to help fill the growing demand for renewable fuels.”
