Welcome to the forum and enjoy your car... you'll love it!!!
My dealer charges $72.50 for an oil change. Plan on spending the better part of a $100.00 bill for an oil change on this car.
As with all cars, you can take it anywhere you wish to have the oil changed, even doing it yourself without voiding your warranty. Just keep receipts.
I would not take the Xfire to one of the quickie lube places etc as it's a different setup most of them people are familier with... and they tend to screw things up once in awhile. IMO you would be better off with this car to take it to the dealer... if they screw anything up your covered.
