Product description

Over time, deposits can accumulate in the fuel system and engine. Carbon deposits and other contaminants can build up on injectors, intake valves, piston crowns and inside the combustion chamber. These deposits can negatively affect combustion, engine performance and fuel consumption. They may also cause rough engine running, knocking or pinging.

Lucas Deep Clean Fuel System Cleaner is a powerful fuel system cleaner specially developed to tackle stubborn contamination and carbon deposits. Thanks to its unique combination of cleaning additives, the product helps thoroughly clean the fuel system and combustion chamber.

Particularly in classic Volkswagens, where deposits may have accumulated over many years of use, thoroughly cleaning the fuel system can be a valuable maintenance procedure. Lucas Deep Clean helps restore original engine performance and contributes to more efficient and consistent combustion.

The product also helps reduce engine knocking and pinging. By improving combustion, it may also help reduce fuel consumption and emissions of harmful nitrogen oxides (NOx).

Directions and dosage

Pour the entire contents of the bottle into the fuel tank before refuelling. One 155 ml bottle treats up to 70 litres of petrol.

Use Lucas Deep Clean whenever thorough cleaning of the fuel system is required. For preventive maintenance, it is recommended to repeat the treatment approximately every 5,000 to 5,500 kilometres. The product can also be used in preparation for an emissions test or vehicle inspection.

Recommendation: replace the fuel filter after treatment

When cleaning a contaminated fuel system, deposits and dirt particles may become dislodged. These can subsequently collect in the fuel filter. It is therefore advisable to install a new fuel filter after treatment, particularly in older vehicles or when the fuel filter has not been replaced for some time. This helps prevent accumulated contamination from restricting the fuel supply.
