OK, I stand corrected.
Oil changes are a messy PITA. It's a good way to learn, but I wouldn't suggest it "just because." It's cheaper to have an oil change place do it.
You can get a cheap trolley jack for $20 and keep it and a lug wrench in the trunk. Are you SURE your spare doesn't have one inside? Most cars do. They aren't easy to use, but they work by the side of the road.
It's worth it to learn this just so you aren't waiting for AAA on the side of 101 for two hours in the middle of the night....you can't go that far on a donut tire, but you can certainly get it off the highway and probably home/hotel/service station.
FWIW, I've changed a tire with that obnoxious stock service jack at 8000 feet on Mauna Loa on slippery and very sharp lava rocks. That was a really expensive rental (I wasn't supposed to take it up there). I can't imagine how long the AAA call would have taken, or if it was even possible.
