Are there synthetic oils that are not derived from petroleum base stocks? If so are they any better lubricants than the major
brand name petroleum based "synthetics"?

What do you mean by "derived from petroleum base stocks?"

All synthetics have base stocks that are predominantly group III/IV/V. Usually "petroleum base stock" means group I/II.

However, most group III/IV/V base stocks originally came from crude in some way. They are just so heavily processed that you'd never know it, which is why they are called "synthetic."

Better how?

PAO is made from natural gas,right? I`ve always wondered how they turn natural gas into a liquid lubricant?

You take the gas molecules and attach them together to make strings (alpha-olefins), and then you take those strings and attach them together to make big crazy funky-looking molecules (poly-alpha-olefins).

No. RLI, Redline,NEO, Mobil, Amsoil, etc and others for sure have esters in the basestock mix, and some (RLI) may even use plant derived esters, but they also have PAO which as mentioned, are assembled using gas feed stocks. (note: a base OIL not "distilled" or hydrotreated from crude). That said esters can be made from petroleum as well. Petroleum is a still a low cost source of organic feedstock.

No. Yes. No. It depends on what you mean by "better". A LOT more to a lubricant than ultimately where the feedstock began it's life.
