This can be simplified depending on your car. GM, for example, requires Dexos oil from any manufacturer. Pair that with an OEM filter and you have a 10,000 mile oil change.
The hard part is having the crush washer on hand and remembering to put it on. In my experience, shops have forgotten it too, used the old one, or have over torqued the plug screw. I think this is why many shops aspirate the oil instead.
