the only difference between a 0w-30 and 5w-30 is at the extreme low temperature that the 0w and 5w are tested at. -25° has never been recorded here in the last 150 years, and both are the same viscosity at that temperature at that temperature. so there's no practical difference for UK and western-europe users.
