I don't think I'd take it to someone who had never even heard of 0w20. 0w20 is kinda unusual- and not everyone is going to stock it. plus your standard oil change at jiffy lube is not going to use a high quality expensive oil. I usually supply mobil 1 to my regular mechanic when I have him do oil changes- we use it on all our cars.
Any reputable mechanic should be able to do it- you have to be careful though- there's a special aerodynamic plate with plastic fasteners over the drain. one guy here took his to jiffy lube and they never put his plate back on- gone.
my car's still new and I got my first oil change (yesterday) free at the dealer.(gave them 4 qts of mobil 1 0w20) but I'll be doing my own if he's going to charge an arm and a leg for it.
good luck-
