Product information

Fuel made of petroleum consists of environmentally hazardous components, including highly toxic sulphur. Biofuel is made from a combination of natural oils or fats. The key environmental benefit of biodiesel is that this pure vegetable oil (PVO) is biodegradable. Biodiesel does not contain any toxic substances, such as sulphur, aromatics or other environmentally hazardous components.

In order to reduce the amount of toxic exhaust gases, governments require fuel suppliers to mix a prescribed percentage of biodiesel with diesel obtained from petroleum. Since 2008, a worldwide standard has been in force which stipulates the maximum permissible amount of sulphur in fuel. The level of sulphur is reduced by mixing biodiesel with petroleum diesel. More and more countries are making the use of biodiesel mandatory, with the mixing percentage varying between countries. Diesel containing biodiesel can be recognised by the letter B followed by a number; B5, B15, B20 or B90 are most commonly found. The numbers 5, 15, 20 and 90 indicate the percentage of biodiesel present in the diesel fuel obtained from petroleum.

Algae as raw material for biodiesel
One of the raw materials for biodiesel is algae. To an increasing extent, algae diesel is considered to be the third generation of biofuels and as a result, its use is on the rise. All fuels contain a certain amount of water. Diesel is less refined (filtered) than petrol, so it contains more water. Biodiesel is hygroscopic, which means that it attracts moisture from the surrounding area due to its chemical composition. The combination of having relatively more water in standard diesel and the hygroscopic properties of biodiesel therefore means that a lot of moisture is present.

Algae like moisture; it makes them grow. Just like other plants, algae also grow more quickly as the temperature rises. One property of sulphur is that it limits the growth of algae. However, as the amount of sulphur in the fuel is gradually decreasing nowadays, the algae have more of an opportunity to multiply in the fuel storage system and the fuel system.

Sludge blocks fuel system
Algae can be identified visually as sludge and this sludge accumulates in the fuel storage system and the fuel system. The sludge spreads from the fuel tank to the fuel filter via the fuel pipes. The fuel filter of a diesel engine contains a water separator that collects the moisture in the diesel and prevents it from entering the fuel pump, diesel injectors and engine. The algal sludge accumulates in the filter and will block the filter after a while. The result of this is that the engine will run more and more poorly and at a certain point it will no longer even start, as the fuel is prevented from entering the engine.

The car will then have to be taken to a workshop. In the workshop it will be discovered that there is sludge in the fuel filter, after which the filter will be replaced by the mechanic. The vehicle will now drive well again and the car owner will be on his way. However, this will almost certainly only be for a short period of time. The algal growth in the fuel tank and pipes will continue as before and the issues will start all over again very soon. The engine will start to run poorly again and the customer will have to return to the garage with the same problem. That is the last thing the customer wants.

Another adverse effect of having algae in your fuel is that they may cause defects in the fuel pump and the diesel injectors. Due to strict environmental requirements, these parts have become more and more accurate and therefore more sensitive. Even the tiniest particle, invisible to the eye, may cause a severe fault in the high-tech components. The fact that the components are subject to extreme requirements makes them highly expensive. It is therefore better to avoid having to replace them.

Requirement: clean the entire fuel system
It is highly important not just to replace the fuel filter, but also to clean the entire fuel system. Diesel Anti-Bacteria contains a product that kills living organisms, such as algae. Attention: these products do not remove algal growth. In extreme cases, the amount of algal growth in the fuel system will be so great that it can no longer be cleaned with an additive. Manual cleaning is the only solution to this. After the manual cleaning, JLM Anti-Bacteria prevents algae from growing and keeps the fuel system clean.

It may happen that you have no issues with your car in your own country or during the winter, just when you are abroad or during the summer. So if you have been on holiday abroad and you car starts to run poorly after a while, just remember this article. The algae have nested in the fuel tank and are slowly but steadily spreading throughout your vehicle's fuel system. And algae don't consider your vehicle's make, type or model. They are everywhere, from private cars to delivery vans and lorries. Algae appear wherever biodiesel is present.

JLM Anti-Bacteria is suitable for all fuel storage systems, fuel transport systems and all diesel engines with and without turbos, and all common rail systems that run on regular diesel fuel.



  • Eliminates and prevents bacterial growth
  • Cleans the fuel system
  • Prevents the fuel filter from getting blocked

How to use:

Effective treatment
A good mix of Diesel Anti-Bacteria is essential for an effective treatment. Ask your JLM dealer for the guidelines. Diesel Anti-Bacteria has the optimum effect if it is present in the fuel system for 24 hours. The cleaner the fuel system, the more effective JLM Diesel Anti-Bacteria will be.

JLM recommends the following cleaning method:
1. Determine the amount of fuel in a full tank
2. Calculate the amount of JLM Diesel Anti-Bacteria required as 1:1000
3. Drive the vehicle until the tank has 25% fuel left
4. Use a drain to remove any water from the bottom of the fuel tank
5. If a lot of sludge is present in the tank, clean the tank thoroughly to guarantee the best treatment
6. Add the calculated amount of JLM Diesel Anti-Bacteria to the tank. COMMENT: Avoid contact between Diesel Anti-Bacteria and your skin or eyes. We recommend taking protective measures. Read the Material Safety Data for more information
7. Fill the tank with diesel after adding JLM Diesel Anti-Bacteria
8. The Diesel Anti-Bacteria is automatically mixed with the fuel while filling up
9. Do not use the vehicle for 24 hours, to allow the Anti-Bacteria to do its work properly
10. Use a drain once again to remove the water with the dead algae
11. The treated fuel is now ready for normal use. Enough Diesel Anti-Bacteria is present in the tank to clean the tank and the fuel lines

IMPORTANT: if the fuel system is severely contaminated with sludge, slime or condensed water, the tank must be manually cleaned before the Diesel Anti-Bacteria can be added to achieve the best possible result. In this case we recommend checking the fuel filter as well. Replace the fuel filter if required.

A 250-millilitre squeeze bottle with a dosing system is available for private cars and light commercial vehicles. Add 25 millilitres of Diesel Anti-Bacteria for every 25 litres of fuel. Add 50 millilitres to the tank after filling up with 50 litres of fuel.

A 1-litre can is available for larger fuel tanks, e.g. for lorries, agricultural machines and vessels. Use a 100-millilitre measuring jug to add the correct amount of Diesel Anti-Bacteria. Add 100 millilitres of Diesel Anti-Bacteria for every 100 litres of fuel.
