I plan on taking mine to the stealer to do the service. Where I bought it they will do the service for 17 bucks.
Personally I have total confidence in the dealer's oil and how long the 6.2 will last is the farthest thing from my mind. Wellll, maybe if I was wanting to get in the Ripley's book.
We have to do what we feel comfortable with, so that makes us both happy.
have fun out there.
