Do a search. Everyone is too lazy to answer you because you are too lazy to hit the search button
 
Providing you are not on any sort of AVS schedule, I'd use any full synthetic 5W/40 such as Halfords (was on buy one get one free last time I was there - so that's 10 litres for £33) or Synta Gold (about £24 for 5 litres from GSF). I use either of these in my S3 and in my Ibiza, changing it every 5000 miles / 6 months.

If you are on AVS then the manual should tell you which one of the various specs you need to use - but expect to pay a fortune for it (like £10 a litre).
