HIGHTEC FUEL SYSTEM CLEANER ULTRA is a high-strength petrol additive that cleans the entire intake and fuel system, from valves and injectors through to the combustion chamber. Its concentrated detergent chemistry removes the carbon and varnish deposits that rob an engine of power and raise consumption. The result is smoother running, lower emissions and corrosion protection, making it especially valuable for direct-injection engines.

Purpose and specifications

This additive suits all petrol engines and is particularly recommended for direct-injection (GDI/FSI) units, where deposits on valves and injectors are most pronounced. It cleans injectors, intake valves and the combustion chamber for more complete combustion while protecting metal against corrosion. As a fuel treatment it carries no vehicle-specific OEM approvals; one container is added to the tank before refuelling and treats up to 50 litres of gasoline.

• 0.250L container treats one tank of up to 50 litres of petrol
• Cleans injectors, intake valves and the combustion chamber in one pass
• Reduces emissions and fuel consumption while restoring engine response
• Protects the fuel system against corrosion for reliable running

When to use / change?

Use it when you notice rough idling, hesitation, higher consumption or rising emissions, and as periodic treatment to keep the injection system clean. A practical routine is every 3,000 to 5,000 km or at each oil-service interval. Add the dose to the tank before refuelling. It works across the engine's normal operating temperature range, and stored sealed away from heat and sunlight, shelf life is approximately 5 years.

Frequently asked questions

Is it suitable for direct-injection engines?
Yes. It is specifically recommended for direct-injection petrol engines, which are most prone to valve and injector deposits.

How much fuel does one bottle treat?
One container treats up to 50 litres of gasoline; add it to the tank before refuelling.

How often should I use it?
Use it periodically, for example every few thousand kilometres or at each service.

Suitable for: all gasoline vehicles, especially direct-injection engines. Always verify the exact approval against your vehicle's owner manual before use.
