FUELSTAT® Plus – Fuel Testing Kits

Where to get fuel testing kits for microbial contamination

Do you use middle distillate fuels like diesel or jet fuel?

If so, fuel testing kits can help you prevent costly contamination problems caused by microorganisms that can exist and thrive in fuel . Get the latest immunoassay fuel testing kits on our product page, or read on to learn more.

Fuel testing kits

FUELSTAT® Plus is offered in two different variants for Diesel and Jet Fuel. Both variants are supplied in boxes of 8 and come clearly marked for Aviation (refers to aviation fuel – see Aviation Fuel Testing), or Diesel and come with full instructions in each test.

FUELSTAT® App

To support the test kit we provide a free to use App for use with Apple or Android devices which analysis the test results and records reports within the system portal:

What are fuel testing kits used for?

Different types of fuel testing kits are used for various purposes, such as determining water levels in diesel or the quality of petrol.

Some of the most commonly used tests are the ones that detect microbiological contamination in diesel, jet fuel and all related derivatives.

This microbiological contamination is also known as diesel bug or diesel fungus. In jet fuel, it’s known as jet fuel fungus.

Microbiological contamination is made up of certain strains of bacteria, yeasts, and fungi that are dangerous to fuel. These contaminants are particularly prevalent in middle distillate fuels, which we know as jet fuel and diesel fuel.

You can now get a fuel testing kit specifically for microbiological contamination, which enables you to identify contamination at the earliest possible stage. Treating contamination and the issues in the early stages is faster, cheaper, and less risky than it would be in later stages.

What issues does microbiological contamination cause?

Microbiological contamination often creates operational issues that can disrupt the use of an asset, such as an aircraft or generator. For example:
  • A tank builds up microbial matter until it can no longer be used and requires cleaning
  • A generator engine fails to fire up because its filters are blocked by contamination
  • A fuel quantity indicator in an aircraft functions incorrectly because of a microbial biofilm coating the probes that read the fuel levels.

In a very serious scenario, microbial contamination can seriously damage tanks themselves. Left unchecked for too long, it can lead to Microbially Influenced Corrosion (MIC) of the tanks because of the acids it produces.

When microbial contamination reaches severe levels and produces these acids, it can lead to serious safety and environmental risks. For example, a large tank could develop a leak so that fuel escapes into the ground. Or in the case of commercial aircraft, a severe blockage could cause engine failure and put human life at risk.

What is a fuel test kit looking for in the fuel?

Quite simply, a fuel testing kit will measure directly or indirectly the microbial contamination in a fuel sample. Depending on the type of test, it may identify the type and quantity of microbes. There is always some presence of microbes in fuel, but tests will indicate if it is a negligible, moderate, or heavy amount.

The scale of the contamination indicates the actions that are recommended to treat the infection. As an example, a tank that has a moderate reading may require a simple application of biocide. Heavy contamination may require the emptying and cleaning of the tank and treatment of the fuel through a process known as fuel polishing.

Processes such as tank cleaning and fuel polishing come at a high cost and will put the asset out of action for a considerable length of time, therefore, it is best practise that a fuel management strategy includes a testing regime that tries to catch microbial contamination at the earliest, easiest and most cost-effective stage.

Do all fuel test kits work in the same way?

There are two distinct types of fuel testing kits when it comes to microbial contamination.

One group of tests called CFU growth tests look for microorganisms in a sample that are culturable on the agar-based media of the test. This means the test result may be misleading, as the sample may include species that are present but harmless to the fuel itself. For example, a common flu virus or e-coli microbes may be picked up by the test, despite causing no issues in fuel. Also, it will miss out on all microorganisms that cannot grow in culture.

Another group of tests, known as ATP tests (Adenosine Triphosphate) look indirectly for light emitted from cellular ATP (cATP)-mediated reaction, as an indication of the microbial load in a sample. This method gives results rapidly but requires investment in special equipment and could be considered relatively complicated to use to non- scientific trained users.

A newer type fuel test, known as an immunoassay test kit, has a much more focused testing scope. It looks for only the specific bacteria, yeasts, and fungi that are known to cause damage to fuel systems and ignores the rest.

What are the main types of fuel testing kits?

The first group of fuel tests for microbial contamination are fuel tester kits that search for the total microbial presence in a sample. The main types are:

Colony Forming Units (CFU) growth tests for fuel contamination. These tests are either done in a laboratory using a method known as IP385, or using a method involving something called thixotropic gel which can be done on-site but also requires incubation for a period. These methods both require incubation for 4-10 days to complete the tests.

CFU tests often involve sending fuel, or a test bottle of thixotropic gel, to off-site or testing facilities in the organisation to be either tested and incubated or just incubated. The fuel must be sampled, handled and transported in a very sterile and timely way (within 24 hours). This is to reduce the risks of getting misleading results, which could lead to expensive fuel treatments that aren’t necessary.

These tests look for the light emitted from cellular ATP-mediated enzymatic reaction and give readings in RLUs (Relative Light Units), indirectly indicating the microbial presence in a sample.

ATP tests are fast and can hypothetically be done on-site, but they require an additional piece of equipment known as a luminometer. Because of this, tests are usually conducted in an off-site laboratory or testing facility. As with CFU tests, fuel has to be transported quickly and under sterile conditions.

These on-site tests are the most modern on the market. They search specifically for the specific bacteria, yeasts, and fungi that are known to cause problems in diesel and jet fuel storage and systems. Because they’re not searching for all microbial presence in the sample, immunoassay tests reduce the risks of misleading results.

Why fuel users around the world are choosing immunoassay fuel testing kits

Easy to use. Immunoassay fuel test kits are unique in that they do not require a multi-step rigorous process. In fact, after a few minutes of instruction, they are hard to do wrong. The tester is only required to take a sample of fuel, put the fuel or water from the sample into the provided sample bottle, and simply add 4 fuel drops onto the test.

Works in non-sterile environments. Immunoassay fuel tests are also unique because they do not require any sterility measures on-site. Apart from having a clean sampling container, it is not important to be vigilant about hygiene during fuel sampling or handling.

Digitally verified results. Immunoassay test results can be verified and digitally recorded instantly using a smartphone app. This helps in clarifying results and takes away the burden of manual reporting, so there is less possibility of human error.
