Professional kit for thorough removal of carbon deposits from the entire petrol engine.

The BG 6577 KIT is a comprehensive solution that, in three simple steps, frees the engine of carbon and oil deposits throughout its entire range – from the oil system through the injection and combustion system to the emission system.

What the decarbonization treats

• Oil system and piston rings
• Injection system and injectors
• Combustion chamber and valves
• Emission system (catalytic converter, particulate filter, EGR valve)

Why choose BG 6577

• Highly effective prevention for the whole engine at once
• Removes even very stubborn carbon deposits (injectors, valves, oxygen sensor, catalytic converter)
• Restores engine performance to factory-like condition
• Reduces fuel consumption and harmful emissions
• Protects the intake system of direct-injection engines (GDi, TSI, FSI…) from fouling
• Ensures smooth, steady engine running and reduces vibrations
• Helps prevent clogging of the particulate filter (GPF/DPF)
• Reduces the risk of poor starting
• Extends engine life

Suitable for both new and older engines – including the latest direct-injection units.

How and when to apply

We recommend applying it at every engine oil change, ideally starting with the very first oil change on a new vehicle:

1. BG 109 – applied to the old oil before the oil change (engine runs for approx. 20 minutes at 1200 rpm, without load)
2. BG 115 – applied to the new engine oil
3. BG 208 – applied to a full fuel tank
