Hi Nick..
Oil will be a good quality 10W40 semi-synthetic.. At a guess, around 3.5 - 4
litres. Drain plug is on the sump somewhere, usually the bottom, but could be
at the side. Don't forget to change the filter as well, and only use a genuine
one from the dealers.. only about £6 - £7.. not worth using any other however
cheap it is.
Fill as normal, and keep checking the level, then start the engine to fill the
filter, allow to stand a few minutes then check again, and top us as needed.
Plugs... NGK or Nippon Denso.. don't bother with anything else.
John
