Mobil extolls the virtues of PAOs on its website. The company is too big and has pockets too deep to play fast and loose with the truth publically. Funny thing is, ExxonMobil has both synthetic markets covered. They're vertically integrated to produce the raw PAOs that go in their own Mobil 1 oils, and also sell to other blenders, yet they're also a top player at the forefront of hydroisomerized Group-III base stock development and production. And, they'll sell upgrade equipment to other refiners to produce Group-III base stocks, or even complete turn-key refineries. The company's laughing all the way to the bank with a win-win situation.
