How do you know if your diesel fuel is clean? You need to sample and test your fuel frequently. The sampling of your fuel is the key to finding out whether or not a problem exists. While water in the tank may be visible, the quality and relative purity of the fuel is not. For this reason, periodic testing is a must.
We at Green Coastal recommend annual fuel sampling and testing. We draw our samples from the bottom of each tank. The bottom of the tank is where sludge, water, and particulate matter tend to settle.
Once we have the sample, it will provide us with a visual metric of the fuel and will reveal any problems it may have. If contamination is evident, we will proceed to a series of on-site diesel tests.
On-Site Diesel Fuel Tests
When we test, here are the things we are looking for:
- Clarity. What is the level of sludge, bacteria, and other contaminants?
- Water. Freestanding water will accumulate on the bottom of the tank until it is stirred up.
- Moisture. This is evident if the fuel appears hazy.
- Mold. Growth usually occurs within 48 hours.
- Bacteria. Active growth in 72 hours
- Final Testing. Fuel is once again tested to guarantee that its quality is at or above industry standards.
- Significant freestanding water. If this is the case, additional testing can be done to determine the depth of the water at the bottom of the tank
If we find mold or bacteria, it must be addressed immediately. A highly potent biocide can be used to destroy this microbial growth. If the growth is highly pervasive, strands of the bacteria can be seen growing on the sides of the glass bowl of the fuel/water separator. Mold can also attach to the top and sides of the tanks.
If you are diligent in the testing of your fuel, you will keep your fuel systems running at peak performance. Green Coast Management is your solution when it comes to your fuel testing needs.
