partner had worked with mobil on this. I have heard this rumor years ago and have looked repeatedly for any info regarding this. The only problem I have ever seen with mobil 1 was the AV1 and they stopped producing that some time ago. I haven't been able to find any facts regarding mobil one not being a true synthetic. The rumor resurfaced again after the new trisynthetic formulation about what 6 months ago.....seems likely if it were true that there would be some kind of state or federal attorney general reports somewhere. Or some kind of consumer action...I tend to lump it into the competitors disinformation files.


I did not say anything about the FTC. It was mentioned that the poster was from "Down Under". Perhaps the suit took place outside the US?

If you go to this site and search the ftc files for mobil you won't come up with a single case regarding mislabeling mobil oils. The oil that the court case involved was Castrol not mobil.Castrol also won the right to call theirs synthetic. The castrol rs10w60 is required on the M5s and its quite a bit more than 8.00 here at the dealer. I have only found it at the dealer here. The bmw synthetic 5w30 which i use has a castrol part number on it and is supplied by castrol to bmw. They used to use a valvoline synthetic as the bmw oil now they switched to Castrol. I am guessing that its based on costs to bmw. I am sure that Mobil would not blatantly claim that the mobil one trisynthetic is 100% synthetic unless it was. The
U.S. is far too lawsuit happy for them to do so.Especially since the castrol court case had happened just prior to the trisynthetic formulation anouncement.


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?
