Are all model year 2007 vehicles required to use ULSD?
A. All model year 2007 light-duty passenger diesel-powered vehicles are required to use ULSD fuel, but some medium-duty and heavy-duty diesel-powered model year 2007 vehicles are built with 2006 model year engines that are not equipped with sulfur-sensitive advanced emission control systems. These vehicles do not require ULSD fuel and EPA does not require that these vehicles be fueled with ULSD fuel. Letters from EPA to the American Trucking Associations and Engine Manufacturers Association address this issue in more detail. Vehicles that require ULSD fuel have specific labels on the dashboard and near the fuel inlet indicating that they must be fueled with ULSD fuel. Vehicles without these labels may be refueled with Low Sulfur Diesel (LSD) or ULSD fuel. Also check the owner’s manual for which fuel your vehicle is required to use.
