So i was in target strolling the automotive isle (btw they have a DC> AC power inverter for $5 now....)

and i got some STP fuel injector cleaner. Well low and behold i checkout and go to my car (imagine that).

Start it to get things warming back up, go put the STP in, once the bottle is empty, oh ****. I did that backwards!

It'll be fine as long as you have more than half a tank. It'll just take a bit to fully mix.

Well the tank is full save 10-15 miles. My problem was I did it when the car was running....

You're talking about the STP you dump in the tank, right?

Yup, fuel injector cleaner, black bottle, I did it when the car was running.

No problem. Won't hurt a thing.

Ya, that should be fine. I thought you meant you put the cleaner in an almost empty tank.

I figured it didn't kill.

Whatever doesn't kill ya makes ya stronger....

It was stronger in the top end afterwards though, musta knocked some crud out.

Is it true that if you use off the shelf fuel injector cleaner once you've got to continue to use it. Sort of once you start using it, you can't stop. If that makes any sense?

I'm not sure if you HAVE to keep using it. Well, if you want to keep the fuel system/injectors cleaned well, you should use it regularly. But I don't think you'd have problems if you don't use it regularly, other than dirty injectors once in a while. Is that what you meant?
