What is the feeling on using fuel injector cleaner / fuel system cleaner additives to the fuel once in a while?

I wouldn't put anything in the tank except for Premium unleaded. Since January 1, 1995 no gasoline has been sold in the US without an approved detergent additive package. I doubt that anything you pick up at the auto parts store is going to do anything more for you.

The best way to keep your fuel system in good shape is by a) not running the tank empty (like I did..) and b) avoid filling your tank at a station where there has just been a fuel delivery.
