Premium fuel. 91 or higher. i just purchased a 2004 Audi A4 and the previuos owner had run regular. The engine was a little sluggish. i started running high test and within a month I felt a notasable improvement. aso ran a can of techron through it.
good luch and always use a the least mid grade if yu want the best performance and engine life.
