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.
