My wife has a VW CC and has 140,000 miles on it, she has used ARCO premium gas 100% of the time since it was new. Her company pays for her gas with an ARCO credit card that's how I know she has only used ARCO. Anyway, it started running rough and fuel mileage dropped. The VW mechanics had to clean the valves, they said it was because she did not use Top Tier gasoline. I hope everyone learns from this. It cost me $1200. Below are photos of the valves.
