Product overview
Injection Cleaner is a petrol fuel-tank additive that targets deposits on injection valves, intake valves, spark plugs and inside the combustion chamber. As these deposits build up they can cause rough idling, hesitant throttle response and harder starting, so removing them helps the fuel system work the way it was designed to.
The product mixes automatically with fuel once poured into the tank, so there is no separate mixing step, and it can be used either as a preventative measure at regular intervals or to address running problems that have already appeared. Because it also helps protect fuel-system components from corrosion, it supports the same components a workshop injector service would target.
Key benefits
- Removes deposits from injection valves, intake valves, spark plugs and the combustion chamber

Application
Pour the full 300 ml can directly into the fuel tank. It mixes automatically with the fuel, so no further action is required. Use preventatively at service intervals, or repeat the treatment if running problems reoccur.
