Heavy Plant & Equipment

Simple, Fast, Cost-Effective testing

Time is money so keep the wheels turning. FUELSTAT® provides rapid detection of microbial contamination in fuel.

Whether its mining, construction or some other function using Heavy Equipment, often in remote locations with limited fuel supply options, time really is money. The sheer size of some of this equipment, and the cost of running  them, means that they are usually transported to site, so a breakdown can lead to considerable recovery cost, reduced productivity, or expensive downtime.

Therefore, protecting the fuel that powers equipment should be a priority for any site, and this includes careful monitoring and management of microbial contamination (a.k.a diesel bug) because:

  • Diesel engines are at high risk of microbial contamination. Modern diesel fuels always have at least some level of microbial contamination. And when fuel storage facilities are not sufficiently maintained, contamination has more time to grow to dangerous levels.
  • Severe microbial contamination could mean disaster. If contamination grows quickly between tests, it can be transferred to equipment and stop them from working.
  • Traditional fuel tests are inconvenient. Testing for contamination usually involves hiring an external team, sending samples off-site, and waiting days for results.
  • Contamination risks are often underestimated. Many maintenance contractors do not realise how fast diesel bug grows, or the danger it presents.

The only way to have total confidence in fuel quality is with an appropriate fuel maintenance program that incorporates regular, accurate testing – so there is 0% room for error.


FUELSTAT® offers equipment operators a simple, rapid solution to control the quality of fuel used to power your assets.

Traditional approaches to testing for contamination have involved sending samples away for days or even weeks then having to return to where the asset is located to fix the contamination. FUELSTAT® testing is done right at the tank, there and then so informed decisions can be made almost instantly in one visit.

ASTM D6469 Section 8.5 states that samples must be tested within 24 hours to be a reasonable representation of the sample taken. FUELSTAT® provides results in 15 minutes so as well as avoiding extra work and cost in sending samples away it allows engineers to make informed decisions when they are on-site, not days or weeks later.

FUELSTAT® is based on immunoassay antibody technology, which is widely used in the medical industry to rapidly and accurately detect such things as pregnancy, prostate cancer and hypoglycaemia. Put simply FUELSTAT® only searches for the specific microorganisms that are known to thrive and do damage in diesel and jet fuel.

FUELSTAT® is simple to use, simply add the sample to the bottle provided with the test kit, shake it, place 4 drops onto a piece of tissue to remove any fuel or particles trapped in the nozzle before adding 4 drops to each of the sample wells on the test paddle and wait 15 minutes for the results to appear. FUELSTAT® requires little instruction and little in way of rigid sterility controls except for a clean sampling jar. The components of the test kit are also recyclable; however, the fuel sample must be disposed of as per each individual organisation’s own protocol.

If you want instant verification of the result which can be sent or received back to head office within minutes, then the free to download app FUELSTAT® Result will tell you in seconds on your smartphone device.


FUELSTAT® Result will also enable a fully transparent and traceable audit trail to track trends and hotspots, but also provide accurate information to enable effective and more cost-efficient maintenance programs to be undertaken.

It may also assist in identifying assets which are more susceptible to microbial contamination, thus aiding more efficient operational risk management whilst at the same time minimising the risk of contamination transfer while awaiting results from other means. FUELSTAT® provides a quick, simple, accurate, go no-go test kit solution.

Over 100,000 FUELSTAT® tests are used every year all over the globe in many highly regulated industries to monitor microbial contamination in middle distillate fuels. It is compliant with the ASTM D8070 International Standard and is used by organisations the world over from airlines to major fuel operators, from militaries to data centres to keep assets protected.
