I just completed the first oil change on my X and found some interesting stuff. The dual exhaust is not a true dual. The headers go into a single pipe and then is split back out into duals at the rear axle. The oil drain plug is covered by a plastic "drip" cover that must be removed to gain access to the plug. The book is right on at a refill capacity of 6.9 quarts including filter. The battery tray has a drain hose coming down to the front right of the car. If you get a chance, look under your car, you will see a lot of interesting things!
