I just got an '01 Yukon XL (love love love it) and had a question about oil filters. I always use synthetic on my vehicles and run it around 8000 miles, but I like to change the filter halfway through. My other vehicle is a Jeep with the 4.0 and the filter is on the side of the motor. I can change the filter without changing oil and lose only what drips from the filter, but didn't know if that was possible on the Yukon with the filter being under the motor. Any input is greatly appreciated, thanks!
