Thanks everyone! Oil Changer, I'm in SoCal.
Well, I just did the oil change. Had to run to the store halfway through to buy a filter wrench since whoever installed it last put it on so [censored] tight. And I guess this is one of these annoying types of cars where the sideways-mounted filter leads to unavoidable oil spillage all over the place upon removal.
Gonna take the car Jeep out on a drive later and I'm sure it will run great.
So this reminds me, I know that when you first start a car with a new filter and oil, the motor runs dry for a few seconds while the filter fills up. Is there anything you can do to help it? I think I've read about people pre-filling the filter but I don't know if really makes any difference and presume that oil will spill out when you orientate it sideways for the install.
