do it yourself i have freinds that work at speedy oil change places and yes they do keep boat plugs in stock for when they mess up your oil change plug
also they use brake kleener to clean your dipstick!!! had to tell them stay the hell away from my truck!!!!!!!!!

 

The dealership close to me was having a special not too long ago. Call and make an appointment and they will change your oil for free.

I wouldn't trust any "car spas" or 10 min oil change shops, last few times they cross threaded the drain plug.

My last boss was telling me they pulled his truck around the shop and gave him the keys. When he checked the oil just to be sure there was none in it.
