You want esters?
Google "Red Line".
Their oils use a significant proportion of Grp V basestocks.
G-Oil was (and almost still is) supposedly a bio-based oil, which would involve esters by definition.
There's also an Ohio company called Renewable Lubes (RLI).
They offer oils using a corn oil derived basestock.
I'm sure there are others as well.
+1, and there are a limited of others, since you're going up the pyramid to get the best.
