So they shouldn't be putting anything else in either. I would just ask them about the ester oil the manual says I am supposed to be using. When they give you that confused look I would remind them the manual clearly states that is what they should be using and ask if they were going to.
I was pleasantly surprised to see my dealer ship actually knew what it was and didn't even second guess me on putting it in. I don't know if they would have if I hadn't said anything but after I did there were no questions asked and I saw them put it in.
