I insisted on my first A service that they drain from the bottom. I looked at the invoice when I got home; I did not see a charge for a new washer and called them. They told me that they had indeed drained from the bottom and the service included the washer. I'm not sure I believe them. For the first B service I said do it any way you want. I'm not keeping the car past the warranty and if it blows up before, it's on them.
