Fuel System Cleaner Advanced (J42011)
Petrol Additive
This is an advanced blend of specially selected cleaning agents that together dissolve deposits formed in the fuel systems of petrol engines. It removes varnish, carbon, and resin from single and multi-hole injectors and other fuel system components.
Benefits of use:
- Effective cleaning of the entire fuel system: tank, pump, injectors
- Improvement of the shape of the dose and the composition of the fuel-air mixture
- Cleaner combustion and reduction of HC and CO emissions
- Removal of carbon deposits from valves, grooves, and piston rings
- Improvement of compression and engine smoothness
- Stabilisation of fuel containing alcohols
- Compatibility with modern technologies and synthetic petrols
Capacity:400 ml
Catalogue number:J42011
How to use?
Preventively (every 10,000 km or during periodic inspection):
400 ml Fuel System Cleaner Advanced + 400 ml Fuel & Emission Improver per 50–60 l of petrol.
Correctively:
- Injection engines: add the product to 10–15 l of fuel through the tank
- Carburettor engines: add through the fuel pump
- Always also add 400 ml Fuel & Emission Improver
WARNING: Exercise caution during use – the product may damage paint.
The product can be used without concerns about the manufacturer's warranty.
The product:
- reduces the risk of LSPI occurrence
- reduces exhaust emissions
- improves performance and restores engine power
- neutralises acids formed from fuel oxidation
- stabilises fuel against moisture, corrosion, and decomposition
Compatible with systems:
- indirect and direct injection
- E10 fuels, ethanol
- GPF filters
- catalytic system
Fuel system contamination:
Modern petrols contain alcohols, which react with water to create an acidic environment in the tank. This leads to the formation of varnish, tar, and resin, contaminating the fuel system. Additionally, contaminants affect sensors (e.g., lambda sensor, EGR valve), which send incorrect data to the ECU, resulting in increased fuel consumption, engine speed fluctuations, and power loss.
