Why you should use JLM Rapid Fuel System Clean

Our diesel fuel system cleaner is highly concentrated and enters the motor undiluted via the fuel filter. This allows the diesel system cleaner to effectively remove soot deposits in the fuel rail, from injectors, valves, pistons, and from the combustion chamber. This saves you time and money as your vehicle will run optimally after JLM Rapid Fuel System Clean J02330 gives it a powerful diesel purge.

As the engine gets older and its mileage increases, power loss occurs, dirt builds up and the engine will start to run less efficiently. The build-up of dirt is responsible for the piston rings starting to stick to the piston and no longer being able to press against the cylinder wall. As a result, leaks occur between the pistons and the cylinder wall, compression in the cylinders decreases and oil consumption increases because the oil scraper ring no longer retains oil. Our concentrated diesel system cleaner will help prevent this and make your engine run more efficiently.

Help your car get through its general periodic (MOT) inspection.

Diesel cars are checked for soot emissions during their general periodic (MOT) inspection. If the quantity of soot is too great, the car will fail. Take preventative measures and use JLM Rapid Fuel System Clean and give your vehicle a diesel purge.

Because JLM Diesel Fuel System Clean provides a cleaning boost, soot deposits are removed and soot emissions will decline. JLM Diesel Fuel System can make the difference between an MOT pass or fail - that’s how important using a good diesel system cleaner is. The super-high concentrated cleaner consists of specially developed and a unique combination of additives. Diesel Fuel System also prevents engine problems such as knocking on part load and irregular idling.

JLM Diesel Fuel System Clean is suitable for internally cleaning all (severely) contaminated old and new diesel engines and for resolving less well known diesel faults and engine problems.

Replace the fuel filter for best results

Our diesel fuel system cleaner works best when you replace the fuel filter before using it. Then, fill the new filter with JLM Rapid Fuel System Clean and allow the engine to run undiluted on the additive.

How to use JLM Rapid Fuel System Clean

Here’s a quick guide to using this powerful diesel system cleaner:

  1. Identify the diesel fuel filter in your vehicle and take it off.
  2. Fill a new fuel filter with JLM Rapid Fuel System clean.
  3. Fit the new fuel filter to the vehicle.
  4. Add the remaining diesel fuel system cleaner to the fuel tank.
  5. Start the engine and make a short test drive. JLM Rapid Fuel System Clean will start working right away.
