Think of this as a deep clean and an espresso shot for your engine. RAVENOL Petrol Performance Optimizer Premium is a high-quality additive designed to tidy up your fuel system from the inside out. Over time, even the best engines get clogged with carbon deposits, fuel residue and the odd bit of grime from day-to-day use, and that’s where this little bottle works its magic.
It cleans everything it touches – injectors, spark plugs, fuel lines and combustion chambers, helping restore smooth running, sharper throttle response and better fuel economy. It’s ideal for use between services or whenever your car starts feeling a bit lazy or thirsty.
Running E10? No problem. This additive helps combat the moisture and corrosion issues that come with ethanol-blended fuels. It’s also brilliant for direct-injection engines, which are especially prone to carbon build-up.
Certified by TÜV Nord in Germany, this isn’t some overhyped miracle potion – it’s proper chemical engineering designed to keep your car performing as it should.
Just pour the full bottle into your tank before filling up (treats up to 60 litres of petrol) and let it do the hard work while you enjoy the drive.
Why You’ll Want It:
- TÜV Nord certified, tested and proven to work
- Restores performance and smooth running
- Cleans injectors, spark plugs, fuel lines and combustion chambers
- Helps improve fuel economy and throttle response
- Protects against corrosion and moisture in the fuel system
- Safe for catalytic converters and lambda sensors
- Perfect for cars running on E10 or with direct injection
- Easy to use – pour it in, fill up, and you’re done
