Top Engine Cleaner... WTF?!

I went to the dealership today to get a "can" of it... and dude looked at me like I was lost in time. "Sir, we stopped selling that product years ago, what year is the vehicle? Oh, it isn't intended for injected cars..."

So I am standing there w/o a clue (no part number) and have to leave with my tail between my legs, after he shows me some "newer" products that may work the same... One was called "Cleen" and sounded like the trick.

So, now I have a few questions:

1) What is the GM P/N for Top Engine Cleaner?

2) Does this go in a full tank of gas, or am I supposed to pour it in through the up-pipe as described elsewhere?

You do the top engine cleaner and they will be calling you Smoking Joe.
You pour the Top Engine cleaner thru the throttle body and it cleans up carbon build up and puts on a smoke show. I would change my oil after doing it.
