You can!!!I can guarantee the vast majority of drivers in the UK and Europe have their vehicles serviced in accordance with the respective manufacturers scheduled intervals.
I think that you're assuming that because you don't know the differences between fuels and lubricants (if any) between regions and that because you or anyone you know have experienced premature engine wear, this must be a marketing plan to drive revenue. The 'I do this all the time and it never had a problem' position could be valid in many situations except for preventative maintenance.
People are more aware here because more do their own oil changes as well as other work in their cars. It stands to reason that they would be more aware than someone in the UK who has somebody else change their oil every 12000 miles. I merely suggested that for the cost of one 318 GBP oil change, the OP can do 5 oil changes himself. He can can double his service intervals and save 150GBP. It's just a suggestion, so much for marketing.
