Penzoil is at least upfront that they make their synthetics from natural gas.

Mobile-1 is happy to tell you that they dont use natural gas.

But that doesn't mean that they dont use hydrocarbons pumped from the ground to make it. Synthetic is just a marketing term: http://xtremerevolution.net/a-defining-moment-for-synthetics...
