You do as you wish. I will never purposely use an oil that is not approved for use in my car.

To put your mind at ease, next time you have the dealer change your oil, ask for the container the oil came in to make sure it is not Mobil 1 but Mobil 1 ESP X2!

Oh: you better watch them actually put in the oil, because the dealer may "ghost" you and show you the container without you knowing if the oil in that container was actually was used!

My dealer takes oil from an 50 gallon drum. I have no idea what kind of oil they use, but I suspect it is made by Mobil.

But for me, Mobil 1 is good enough!
