I'm approaching 25k miles in my Civic and was wondering whether I should run some kind of fuel system cleaner (thinking the Redline or Amsoil ones, or perhaps even just Techron). I usually fill it up at local Shell and Chevron stations, and whenever I've been on longer trips I've filled up at other top-tier stations.
The car's not running rough or having any problems. Is it a smart idea to pre-emptively run an injector cleaner at this stage in the car's life or just a waste of money?
