In that case, you become influenced by recommendations in areas of the world where not all grades of oil are readily available and therefore limiting the options the manufacturer can expect consumers to use.
I wasn't aware there are no 20wt oils available in the UK... I highly doubt they can't get it. If what you say is true they probably don't have it because it's not spec'd for anything over there.
