How to use Diesel test kit

Fuelmonitrix Test Kits are used to check Diesel samples . They are simple and easy to use. They clearly identify if diesel is washed or laundered. This page shows you how to use the Fuelmonitrix Diesel Test Kit. With 4 simple steps detailing how to check for washed or laundered diesel. We also have a you-tube video underneath.

Step 1 - Add Diesel

Unscrew the cap of the FuelMonitrix –Diesel Kit Test. Fill the test tube with the suspect sample of diesel to the marked line. Ensure your fuel sample is taken and stored in a suitable container before transferring to the Fuelmonitrix Test Kit. Sampling directly from a forecourt fuel pump is not advised.

Step 2 - Seal and Shake

Ensure the test tube is fully sealed, shake for about 30 seconds and then hold in an upright position until a separate layer of the mixture has settled at the base of the tube. After 1-2 minutes a positive or negative result is visible.

Step 3 - Positive Result

A Positive result: the bottom layer of the test tube turns a faint pink colour which indicates the presence of Marker Gas Oil Dye in the suspect diesel sample. This diesel sample maybe laundered or washed.

Step 4 - Negative Result

A Negative Result: the bottom layer of the Fuelmonitrix remains clear indicates no presence of Marker Gas Oil Dye in the suspect diesel sample. This diesel sample is unlikely to be washed or laundered diesel.
