(south UK). The 5W/40 for fully synt oil is very common, whereas the 0W/40 (mobil) is more expensive. There is an argument against extreme multigrade for warm tropical climate or for vehicles which runs the whole day. e.g. busses. Then it's probably an advantage to rely on fewer additives for the longevity of the oil.
