Its a mine field ! I service a lot of cars and keep 10 different oils in stock and still dont have the correct one ! Just done a service on a bmw m5 it took 8 litres cannot remember what grade it was but I remember the price £96 for 9 litres ! Ouch
I've just spoken to Citroen Sale and if they were servicing my car they'd use fully synthetic 5w40. There's no harm using C2 5w/30 (low saps) it simply has less particulate in it. I thought it worth a double check so rang Citroen Manchester, they said I could use 4 types, 0/30, 5/30, 5/40, 10/40, I asked type of engine and it's a DV6 TD.
Oil shandy; mix a bit of each in there.
