J03155 JLM Lubricants Petrol Extreme Clean

One of the latest additions to the ever growing JLM stable of trade trusted workshop standard products is JLM Petrol Extreme Clean.

It is the solution to late model cars and engines with severe build up blocking problems in different parts of the fuel system. These contaminations are tough and not easily dissolved with regular fuel additives. The JLM Petrol Extreme Clean blend comprises multiple additives packaged into a highly concentrated 500ml super shot with one bottle treating 40-60 liters of petrol.

It is suitable for all petrol engines including direct injection with or without a turbo or catalytic converter.

Product information

The additive contains detergents that ensure cleaning of the injectors, spark plugs, inlet and outlet valves and combustion chamber

The octane booster in the product regulates a more efficient (read: cleaner) combustion

The combined effect of the 2 above ingredients ensures less deposits of combustion residues in the cylinder and much cleaner exhaust gases

In addition, the additive package ensures that the oily residues and soot particles that originate in the exhaust system burn at a temperature that is approximately 125 degrees lower than normal (comparable to principle of JLM DPF Cleaner and JLM ReGen Plus additives). As a result, the exhaust system is already cleaned at a lower exhaust gas temperature and (and remains) the turbo cleaner. In addition, the efficiency of the catalyst increases, and exhaust gases become cleaner.

Phosphor Neutralization

Depending on the condition of the petrol engine, oil may leak into the combustion chamber. This oil will burn and turn in to phosphor. This phosphor exits via the exhaust system and upon entering the catalytic convertor harms its efficiency, leading to many problems as a consequence. This is remedied with JLM Petrol Extreme Clean. One of the additives within the formula contains an element that neutralizes phosphor (from the combustion of oil) circa 50%. This makes the catalyst cleaner and more efficient. And the service life increases.


JLM Petrol Extreme Clean with every maintenance, at bad engine running, turbocharger problems, black smoke or out of round idle. A can of 500ml handles 40-60 liters of gasoline fuel.

Just fill in the petrol fuel tank. JLM gasoline injector cleaner for apply optimal results every 5,000 km.

These are the most common questions we get from a potential distributor.

Do any of the JLM additives help the performance of the high pressure diesel fuel pump?

J02330 Rapid is perfect for pump and injectors!

Is it OK to use the extreme and the DPF cleaner together. ?

No, this will not have a positive effect. In fact it may cause an adverse effect. And also the risk of overdosing! Never combine fuel additives


Will BluBoost dissolve existing crystal infestation or is it more like a preventative product?

JLM’s BluBoost additive cleans and prevents crystal formation in the AdBlue dosing system. It also conditions the AdBlue fluid for a longer time to ensure proper working of the AdBlue and SCR system. This helps prevent performance loss and the often-subsequent expensive repairs. It also reduces foaming at low temperatures

Is the JLM Engine Oil Flush safe for use with wet belt engines?

Our JLM OIL FLUSH is safe to use with ‘wet belts’ (TBIO). This is mainly because we use non solvent and premium pack of oil cleaning additives.


Does the Petrol Emissions Reduction Treatment also clean the catalytic convertor?

The catalytic converter is not a filter, it functions by converting harmful emission gases into less harmful gases. The filter can become contaminated if for example there has been an oil leak, and when this happens the filter needs to be replaced. There is no additive or chemical that will remove physical contamination from a catalytic.
