I don't post here that much but I do visit for advice from time to time and usually find what I'm looking for with no need to post. So just incase I havn't posted before...... Hello to everyone. I'm sure there must be a thread on here similar to what I'm about to write but I'm damned if I can find it. So here goes, It's that time of year again for me and she's due a service, no I don't mean Mrs Roo I mean my 2000 1.8T AGU A3. I just wondered what everybody used? I've been googling about and it seems a lot of people recommend Fully synthetic 10w40 for their oil. Is this right? I'm sure I stuck semi synthetic Magnetic in last time so your thoughts are appreciated. Also what would people recommend to flush or even would people recommend a flush (some do some dont)? Last time I used Wynns but this time I've ordered Liqui Moly flush. Is Liqui Moly any good or should I stay away? I'm ok with my plugs as I've ordered some bosch super 4's which I've used for years on both my A3 and my old MK2 golf when I was younger. Looking forward to the opinions.
