You realize that the climate in the northwest United States is very similar to that of England, correct?The United States is a far harsher climate than Europe so it is kind of silly to compare their choice of oil. Temperatures here range from 115F to -45F. It is a huge country. Many parts are extremely arid and dusty, while others are wet. Cherry picking an owners manual to claim that some other country's oil recommendation is right and your own country's is wrong, is unconvincing.
Also, yes the southeast and southwest in the US have 'harsher' climates than most of Europe, but our oil specs don't vary by region. So I think that this has more to do with regulation than it does with climate.
