Changed over the fuel filter today, and it was filthy. As I shook out the excess, the fuel that came out was a really dark brown, yuck! Also changed the spark plugs and gave the air filer (pod) a bit of a clean.
Car seems to be running a fair bit smoother now, particularly on idle. Cant really tell if its drinking less yet, but will report back.
(Also changed windscreen wipers, easy another 10-20rw/kw now. )
