Other Capabilities
  Want to know how much additive to use to get to a certian cloud point or cold filter plugging point?
Send us your additive and we'll blend it at specified amounts at each degree to obtain the desired effect. This service is available with B100, biodiesel blends or #2 diesel fuel.
  Our sulfur analyzer instrument can detect sulfur levels in any matrix down to .3 ppm. Please call if you have a specific matrix you'd like tested for sulfur levels.
  If you are experiencing fuel quality issues, we have a number of tests to identify the problem.
  • Bacteria Analysis
  • Water & Visual Clarity
  • % Blend check for B2, B5 and B20
  • Field test kits for Acid Number and Glycerin
