Any idea why?
Because he is old school and he is afraid of what he doesn't understand.
Facts support that there is nothing wrong with the 15000 miles oil changes. It has been around since 1998-1999 and engines didn't start to wear faster. Never happened. Porsche, Mercedes and Audi embraced it. for Porsche, it is now up to 2 years.
Save your money.
