Did they offer you an oil change, after the fuel injection service or state that the chemicals used would deplete your oils add pack?
How effective was the service to your injectors? Were they clogged up? Do you notice any difference in performance after the injector cleaning service?
Yeah, I do notice a difference in performance after the service. The car runs smoother, accelerates better. For my own peice of mind, I'll go ahead and drain the oil this weekend. I've got 6K on the oil anyway, so its about time.
