Now the M5 and the M3 use the 10w-60 from what I've seen on the M3 board it can cost like $8 a qt.
I have heard the same thing about castrol not being 100% synthetic stock. I would be interested to see any press releases from the court case about the Mobil 1. Or could this be a case of someone who sells amsoil making somekind of claim?
You would think that if this was true about the Mobil 1 (since they claim that their product is 100% synthetic) that Amsoil/Redline/Royal Purple would be reporting this on their websites. This is the first time that I've heard this.
Just my opinion.
Not a user of Mobil 1 (except in the lawn tractor - no filter, extreme usage); but this post came up from a respected member of another BMW forum.

<< 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?
