Has anyone else seen the comercial with the XTS, the 350Z and 1 other car which suggests that mobil has new oils which go to 5000, 7500, and 15000 miles? When I change my oil again (another 6k mi or so) I think I will try the 15000 mi one. I bet we still need to change oil filter at 7500 (currently The best filter walmart caries goes to 7500 so that is what limits me from longer change interval).

i just bought the 15k mile one. i am about to change my oil and try it out. though, im smarter than to actually wait 15k miles to change again. only a moron would go 15k miles. i dont care what mobil says, you cant safely go 15k miles w/o an oil change. ill probably go 5k-6k, if my K&N high performance oil filters allow it.
