Only had the car for a couple of weeks (172) and not sure if at last service it had fully or semi-synthetic oil changed.
I presume that it will need topping up regularly between oil changes but not sure if ok to top up with fully synthetic. Will it do any damage if the 2 grades are mixed is what I suppose I'm asking.
Also, how much/often (on average) do you top up your oil?
