Ello just brought my first passat

[rayray1011]

Just got hold of a b5 passat estate my second vw had a mk2 golf gti which I loved but fancied a bigger motor for my fishing, it's a t reg 1.8 20vt auto got 64000 on the clock one owner from new my mates grandads car, it's got full vw specialist service history and its mint. I'm really happy with it only trouble is that it's been sitting for 18 months so had to buy a new battery, but its running a bit ruff ( got a full tank of old petrol ) so need to drain and service it. Anyway what oil is best/ recommended to use with my engine? Cheers in advance
