Yeah, its not like we are talking about how to get a tune on the thing without the dealer being able to tell later via the computer when it blows up.
Its never going to fail from oil. If a manufacturing defect causes it to fail, and they test the oil, how would they tell? They can't.
They probably set it at 6 months becuase they expect the car to get taken to the track and rode hard every other weekend. If you are not doing that though, why waste the time?
