Sorry to ask yet another question about oil, but I looked through previous answers with no success.
Citroen Berlingo 1.6 16v: book recommends 10W-40 or 5W-40 (or 0W-40 for extreme cold down to -30 and up to 40C+). I have a can of Mobil 1 fully synthetic 0W-40 with just enough left in to do an oil change.
Will it be okay to use? Will I be merely 'over protected' against cold weather? It meets the required API/ACEA spec.
Oh, and something that may be useful to the group, cheap bulbs at Lidl on Monday, no idea what they're like, but *some* of their stuff is actually quite good quality, honestly! (A few other things on there too)
