I have always been a fan of mobil 1 synthetic. I used it in my geo and I currently use it in my truck. Its really up to you whichever to decide, but with the amount of driving I do, it works out a little better to me, as I can drive a little longer before changing my oil. (usually 6-8k depending) I used to use Lucas Synthetic Oil stabilizer in my geo, which made a world of difference, especially with regards to gas mileage. I haven't put it in the X yet, but plan on it pretty soon. Any opinons on the oil stabilizer? I have about 15k miles on my X.
