Based on what some other smart people on here recommend, if you feel any stumbling or other injector/ignition issues, you should have the pressured fuel cleaning service done at your dealer. My dealer has a special that costs $129.
But since I do not experience any noticeable injector issues, I will just use a can of bg44 and be done with it. I will probably get the cleaning service done at 60k.
