I hate quick oil change places. I should know, I worked at one back in HS. At least if you bring your own oil, you won't get someone putting the wrong fluid into your engine or trans. Well, maybe... They sometimes forget and start then have to drain it. I've seen them strip oil pan plugs before as well. The best is when you have a hood support that's not front and center. Then someone tries to lower the hood and bends it in half.
The shops that so oil changes on the side are a lot better. You don't have 3-4 different people working on one car.
Although the YJ and TJ don't take that much maintanance. 11 grease fittings IIRC. I do it myself all the time. It doesn't really take long and I can check other things while I'm there.
