VVC-Geeza

A representative from AA came out to the vehicle and brought up the subject. Every other time you fill up with gas, he suggested to add a third of the bottle. He claimed it was excellent if you were like me and didn't have much opportunity to drive on the highway. Reduces carbon buildup, improves gas mileage, and eliminates engine grime. This tried and true by anyone?

The dealer informed me that (supposedly) a software repair is in the works for the next months.
