Couldn't find anything specific, but what I did find is that TruSouth, the blender, is at the same address as Calumet Packaging. Calumet is the parent company of Belray and Royal Purple, and also produces private label products for others. They make Stihl's premix and a couple other company's premixes. VP mixes their own.

Even if they're not using an existing oil formulation that someone else uses, clearly coming up with their own solid product is well within their wheelhouse.
What info do you have?
