DurAlt Fuel Conditioner is an ideal product for fleets.  It has been in use in fleets for over a billion fleet miles and provides an average improvement of 8% to 12% in fuel economy.  In addition, DurAlt increases engine longevity and reduces maintenance expenses. Testing by the National Institute for Petroleum and Energy Research showed that DurAlt reduces smoke in diesel engines by 61% at full load and 1600 RPM.  DurAlt also improves cetane rating in diesel for easier cold weather starting.  It is a fuel stabilizer that prevents oxidation and breakdown of fuel and prevents algae and bacteria growth in diesel.
