<< Now, on to Mobil 1. Did you know that this oil is NOT made from a true synthetic base stock?? It is actually dino oil in disguise!! Which is one of the reasons why Mobil was involved in a court case in the not-too-distant past in which it was LEGALLY determined that they are allowed to market a number of their products as "sythetic" - because they have undergone an elaborate transformation. However, the truth is that the base material is still crude oil.
From my limited understanding of chemistry I believe what they do is turn the base stock into a gas then turn it back into a liquid - ask a chemist how, not me. The point is, a duck is still a duck even after its been roasted. >>
I know that Amsoil and Royal Purple are 100% synthetic, now wondering about Mobil 1. BTW, Mobil 1 and the BMW are not the same thing. The BMW juice has a wider viscosity range than Mobil 1. Further I've heard that the BMW juice is a Castrol product and costs upwards of $40/quart. Can anyone confirm this?
