Sulfur content impacts engine wear, creates deposits, and may affect emissions control system performance. The effects vary with operating conditions. The Environmental Protection Agency (EPA) has imposed limits on sulfur emissions for environmental reasons and ultra-low sulfur fuels are preferred. B100 contains low quantities of sulfur. Sulfur is analyzed in accordance with ASTM D5453. Gorge Analytical, LLC is EPA-approved for the analysis of low-sulfur and ultra-low sulfur diesel.
