Hi Guys,

I am new to Audi after years of driving 3 and 5 series BMWs. I love my newly acquired 09 Audi a8 but I am wondering whether there is something wrong with the car. I only get 240 miles on a full tank, averaging about 10 miles per gallon. I already replaced the air filter and just ordered new OEM plugs. What else should I do/replace to improve the gas mileage. There are no codes.

A8 Lover
