Fuel and engine additives from RAPIDO: injector cleaners for petrol and diesel and an octane booster, one bottle per tank.
How to choose fuel & engine additives
- Petrol engine that idles rough or feels weak: start with the Petrol Injector Cleaner.
- Knocking or weak fuel: the Octane Booster raises the octane number.
- Diesel engine: only the Diesel Injector Cleaner is made for it.
- Every bottle treats one tank with at least 30 litres of fuel: add it first, then fill up.
