first off never take your car to those fast change oil places to include most dealers. I have heard many horror stories about them not changing the filter and or oil and charging you for it. also they could use regular oil vs synthetic to make a buck or 100. Take the time to do it yourself to ensure it is done right. as far as the amuse kit you do not have to take the bumper off there should be a cutout there that allows you to access the oil filter and drain plug.
