Surprised? You have shops that claim to be Euro experts that use wrong oil.Using an oil with the correct approval makes it so you don't have to worry about any of this. I'm actually surprised the shop didn't use the correct oil. Even a quick-change shop is generally a stickler for that. You'll pay for it however.
If I take car to a shop, I always tell them that I don’t want anything complimentary. Just do whatever we agreed on. I don’t want even windshield fluid topped off.
