I bet you can't go 10 post without mentioning exxonmobil.
If the subject is PAO base stock and PAO manufacturing plants near Port TX, you are probably correct since the one of the worlds largest PAO plants is located a short distance away in Beaumont TX.
I could be wrong, but I don't think any of smaller oil brands like RP have the capability to manufacturer PAO/Ester base stocks. Even some of the larger oil companies buy it from others.
