Brilliant 👌🏻
Picked this up for my partner’s bike and he’s well chuffed with it. Bike’s running smoother and starting easier. Just chucked it in with the fuel – no fuss. Would definitely grab it again. Great quality and price highly recommended 👌🏻

Got it running right
Got my carburettor bike that had been sitting for years running smooth without have to strip and clean the carb

Supposed to be good
Didn’t really notice the difference but says it’s doing the engine good. A bit expensive when you could literally put premium fuel in at the pumps that would be cheaper.

Makes a different noise
Honestly can't say if it works well at de-carbonising, it's not really easy to check, but mixed together with premium fuel, the bike started making a much deeper noise and I could feel it pulling really well. I'll keep using it for the next few tanks and see what happens. Expensive though for a can that only treats about 20 litres of fuel.

Not sure...
Not really sure if this made any difference to be honest. Maybe - Worth adding though I suppose.

Utilisé dans une honda 125 cg de 1997 qui commence avoir des traces de rouille à l'intérieur du réservoir. Immédiatement j'ai constaté que ces traces ont viré au noir. Le produit semble avoir fait quelquechose sur la rouille. Aucune incidence sur le régime moteur, consommation ou autre. Après, il faut éviter de laisser à nouveau le réservoir quasiment vide car la rouille redevient couleur rouille et il faut recommencer. Ce n'est pas un traitement définitif mais a fonctionne pour un coût vraiment moindre.
