Dieselcraft can supply your company with a wide range of diesel fuel test kits. From the relatively straightforward DS-1 Test Kit that will check for bacteria in your diesel fuel to the more advanced FCT-100 Diesel Fuel Water Content & Fuel Clarity Test that tests diesel fuel, biodiesel blends, and even heating oil. Because all our tests are easy to use and will provide you with real-time results in 5 minutes or less, anyone can perform the tests. They include all the supplies and instructions you’ll need to look for microbes and water in diesel fuel.

If your company has stored diesel fuel, it’s a good idea to use diesel fuel test kits on it every 90 days to make sure water hasn’t found a way to get into it. You should also get into the habit of using test kits on fuel deliveries to make sure there aren’t microbes and water in diesel fuel before you accept it. It’ll help you avoid a headache later and allow you to steer clear of using diesel fuel that could potentially have bacteria, mold, fungus, or even dangerous asphaltenes in it.
