Requirements by the U.S. Internal Revenue Service (IRS) have specified red dye to be added to all Navy fuels to identify all tax-exempt diesel fuel regardless of sulfur content. Because shipboard acceptance of NATO F-76 fuel is based on visual inspection that is complicated by use of the dye and because of the concern within the Navy over the potential for engine damage, the EPA has grant a discretionary waiver from using red-dyed NATO F-76 fuel. This paper examines anticipated coated
Navy marine gas turbine materials in low-velocity, atmospheric-pressure burner rigs (LVBR) tests to determine if, or to what extent, red fuel dye may affect their hot corrosion resistance.
