Dieselcraft’s #OX-20 diesel fuel test kit tests fuel for oxidation, indicating if it is bad or in need of additives or extra filtering.

Using the in-house testing kit will show results in under 20 minutes. If the fuel is bad the test will indicate a black reaction layer in the test vial. The older and darker the fuel is, the less efficient it is. Left unchecked, oxidation in fuel will lead to tank sludge and filter plugging.

The test kit consists of the oxidation catalyst, five test vials and sampling pipettes. Each kit is good for 20 tests. The tests work on all diesel fuels including #2 Diesel, Red Diesel, Maine Diesel and jet fuels.
