JLM E10 Fuel Treatment J03175 JLM LUBRICANTS

JLM E10 Fuel Treatment is an all in one fuel treatment for cars providing ethanol corrosion protection and valve seat lubrication and protection. In addition it boosts the fuel’s octane number.

Product information

Blending 10% ethanol with petrol might make environmental sense but it introduces technical issues, even with cars that are designed to use it.

Just as food goes stale over time, so too does ethanol. Additionally, unlike petrol, ethanol absorbs water. Once it can hold no more, the water/ethanol mix separates, causing a useless incombustible mixture to sink to the bottom of its tank, leaving the low octane gasoline layer above. As the solutions will never mix again, the tank needs to be drained.

JLM’s solution is to slow down the ageing process as much as possible. The company has developed a preserver within the E10 Fuel Treatment to condition the fuel, which inhibits the process and makes it last longer. To assist with optimum combustion, an octane booster helps to compensate for the slight loss in fuel economy that results from ethanol-laced petrol.

However, even fresh E10 petrol causes issues. The ethanol content increases soot and lacquer deposits within not only the combustion chambers but also the delicate fuel injectors. If allowed to accumulate, engine efficiency becomes impaired, which can be followed by mechanical failure, if ignored.

JLM’s E10 Fuel Treatment cleans these contaminations and prevents accumulation. A further preventative maintenance function forms a protective layer on valve stems and seats, compensating for ethanol’s lack of lubrication quality, thus enhancing engine valve/guide life and reducing the risk of valve seat recession.

JLM’s E10 Fuel Treatment is an easy-to-use answer to these complex problems, which will help your car to optimize its environmental and running costs potential, while using E10 petrol.


Add 1ml to 1 liter E5 or E10 petrol (25 ml treats 25 liters petrol). Use every tank fill!
Special bottle with dosing device, helps to obtain the right quantity.

These are the most common questions we get.

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 JLM Extreme Clean 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 JLM 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.
