System Cleaners

I was thinking about running some fuel system cleaner in my older car. Curious does it really help and if so what kind should I run? Anything else one should do to a older high mileage car aside from normal maintenance?

It sure won't hurt but in certian situations it's not a good idea. Nissan for example dosen't recomend it because they use a pindel-less fuel injector. The additives can hurt it. So check out with the dealer.
