MotoZen FuelGuard is a concentrated petrol system cleaner built for engines that have picked up carbon build-up from stop-start city driving and low-quality fuel. One 300 ml bottle treats up to 60 litres of petrol.
What it does
- Dissolves carbon deposits on intake valves and fuel injectors
- Restores lost throttle response and idle smoothness
- Cleans the combustion chamber to reduce knocking
- Protects against future gum and varnish build-up
How to use
Add the full bottle to your fuel tank when it is between a quarter and half full, then fill up as normal. For best results, use every 5,000 km or every third fill-up.
