DS-1 Test Kit. Test for Bacteria in the Fuel

  • Individual test per package.
  • Works in ANY fuel.
  • This will detect Fuel Microbes (BACTERIA or MOLD) between 24 and 36 hours after exposure.
  • NO spots are good news. Any reaction is bad news.
  • Select DS-1 Bacteria Test plus Fuel Clarity and Water Content Test Kit. One test does it all.

Starting from $16.95.


W-5 Water in Fuel Test Kit

    • This is a PASS or FAIL test.
    • This test will indicate the smallest amount of suspended water in diesel.
    • Depending on the fuel blend and the amount of biodiesel you may see between 1000 PPM and 1500 PPM will be detected.
    • Any detection of suspended water is not good if the detection powder turn 100% pink. The fuel FAILS.
      The kit consists of 5 each test tubes with the reaction powder capsule in them and one transfer pipette.


FT-100 Diesel Fuel Water Content & Fuel Clarity Test

  • Based on ASTM D4176
    Tests Diesel Fuel, Biodiesel Blends Off-road Fuel and Heating Oil.
    Results in less than 5 minutes.
    Non-toxic and completely safe
  • Two tests in one.

  • The Fuel Clarity Test
    Put a fuel sample the specially designed test jar. If the fuel is clear and bright all five indicator marks show through the fuel and the fuel PASSES.
    As the fuel clouds the line disappear and the fuel FAILS.
  • The Fuel Water Content Test
    Take the capsule and open it and pour the continents (powder) into your test jar.
    Shake for 10 seconds.
    The powder will start to settle to the bottom and you will see at the bottom of the jar either the white powder or various shades of pink.
    More than 600 ppm water will turn all the powder hot pink.
    Hot Pink is a FAIL and action must be taken.

Have long term stored fuel? You need to check it at least every 90 days.

When receiving fuel deliveries you had better check it before it is in your tank and you find out later you just got a problem delivered to you.

It is not if water enters your fuel system it is when water enters the system it can cause bacteria growth. Many species of bacteria, mold, and fungus can grow in diesel fuel but not algae.
Algae growth in fuel is a misnomer for the problem. What looks like algae may be in fact asphaltene or diesel sludge/fuel bugs/fuel microbes. Asphaltene is a chemical problem inherent in YEARS OLD diesel fuel or it most likely is a bio-mass that forms around bacteria to protect it.

Until know what exactly what the problem is you cannot treat it and get the desired results….a clean tank and no ore plugged filters or poor engine performance.

Have you used a biocide and nothing got better?

Test the fuel now and we then will know the direction to go.
