I do too, and will continue to as long as I physically can. The OP was concerned about getting older and less able/willing to wiggle under a vehicle to get at the drain plug and/or filter.Finally, most of those places use labor that aren't really qualified in the first place, aka: high school kids, part time help.
I'll always do my own routine services.
I agree that the help at Jiffylube-type places aren't exactly top shelf, but I doubt they're any worse than the chain tire/auto centers that do brake/exhaust/oil changes.
