Fuel system cleaners, in most cases, perform the role of a miracle fix, but at other times, they don’t work instantly but will help keep the system clean but won’t do a full fuel system cleanout.
For the best result, you can talk to your service center and let them advise you on this procedure. It is not every work shop 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 five years now, and it works well for me. First, run the tank down to 1/4 tank, dump it in a bottle, and take it for a long ride.
Normally, I get it on a little, and once it 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.
