The manual for my 2003 VW TDI says to change the oil every 12 months or 10,000 miles.  My dealer says every 6 months or 5,000 miles.

Are they just trying to make twice as much money off my oil changes, or is there a legitimate reason to change the oil twice as often as VW originally printed in the book?
