Fuel system cleaners in most cases perform the role of a miracle fix but in other times, they don’t work instantly but will basically help keep the system clean but won’t do a full fuel system clean out.
For best result, you can talk to your service centre and let them advise you on this procedure. It is not every work shops that can provide you with the detail you need.

How Long does it take for Fuel Injector Cleaner to Work?
Personally, I have used Seafoam for almost 5 years now, and it works good for me . First, run the tank down to 1/4 tank, dump in a bottle, and take it for a long ride.
Normally, I get it on a little and once t gets close to empty, I add some more to keep it concentrated, and go on another ride.
That generally straightens things out. Unless you have other issues, you should see an almost instant result.
