An oil change is quite a straightforward task, but things can go wrong.
Things like stripping the drain bolt, forgetting to prime/fill the filter, overtightening the filter, putting the wrong oil/amount. Etc.
I've heard a horror story where a quicklube place drained the MTF and flooded the engine oil. Needless to say, the car didn't last very long after that.
My independent mechanic (that I trust) only charges $10 to do an oil change if I provide the oil and filter. That might be better idea.
