Not the most interesting post in the world, I have to admit, but she was due for an oil change.
Put a new filter on (ERR3340) and filled her up. There seems to be some debate as to whether you should use 10W-40 or 15W-40. I thought I would try the 10W-40 (Castrol GTX) for a change to see if it makes any noticeable difference.
