Castrol GTX vs. Mobil Clean 5000

Curious, I assumed since Castrol is a part of BP/Amoco they would get their base stocks off of them?

Besides, does it even matter where the base stock comes from? There is only a handful of sources where the dozens of blenders get their stocks from... It's the refining/blending that makes all of the difference really.

It is possible that BP Castrol now gets some or all PAO base stock someplace else other than Mobil, but we do know that in the past they have used Mobil base stock in some of their products:

That link is 9 years old right around when they were bought off by BP. Also it predates the purchase of Pennzoil-Quaker State by Shell to form SOPUS by about 2 years.

It would be interesting to know how each company is getting their base stocks today.

Yes, I said "in the past." Not sure what purchase of Pennzoil-Quaker State by Shell has to do with this.

Here is a more recent article concerning US suppliers of PAO:

October 29, 2008
"U.S. producers of low-vis PAOs, which typically range up to 10 centiStoke in weight, include Chevron Phillips Chemical, ExxonMobil Chemical and Ineos Oligomers. However only two North American companies, ExxonMobil Chemical and Chemtura, have manufacturing capacity to produce the high-viscosity grades, such as 40 and 100 cSt. These often are used as "correction fluids" to balance lower molecular weight PAOs and achieve viscosity targets."

Great info! Thanks for posting this. Mobil seems to be the dominant supplier.

I mentioned SOPUS cause it was also mentioned in the first link from 2000.
