Fleet Fuel Testing, formerly known as Fleet Biodiesel, is a reputable brand that specializes in providing on-the-spot diesel fuel quality tests. Their tests are designed to work with all types of diesel fuels, including diesel #1 and #2, ULSD, off-road, jet fuels, and biodiesel blends. At Fleet Fuel Testing, they offer a range of fuel tests that are simple and easy to use, allowing you to check the quality of your diesel fuel in just five minutes – without the need for a laboratory.

Their tests are the most cost-effective way to identify potential fuel issues that could have profound and costly effects on diesel engines. Their best-selling test is the Water & Visual Clarity Test, which is used to detect fuel with high levels of entrained water or other contaminants. They also provide tests for detecting microbial contamination, which can cause filter plugging and fuel oxidation, as well as tests for diesel fuel degradation.

Fleet Fuel Testing's tests are suitable for use with all diesel fuels, including diesel #1, diesel #2, jet fuels, off-road (dyed) fuels, marine fuels, and biodiesel. These tests are small, durable, and ideal for use in remote locations where laboratory testing is not practical.
