I picked up a mint Toureg 4.2 with only 25k on a few months ago from a Ford dealership and am I'm due for my first oil change. All they claim to have to offer for oil is a synthetic blend. I've never owned an suv, have been a die hard VW guy since I first owned a car. Should I just purchase my own oil or go with the blend for now? I've used full in all my other cars so I'm figuring why settle for anything less on a more expensive vehicle.
