okay im confused about what oil to use for my 1999 A3 1.8t sport. have scanned in the page from my manual but still none the wiser! (see linky) can someone recommend the type (VW 500 01?) and more importantly, a make of oil that is suitable, im on annual servicing if that makes any difference? http://img71.imageshack.us/img71/1939/audia3oilmanualgt1.jpg thanks!
