Solvency and volatility are a two edged sword ....
If you were to try and blend a fully formulated oil using low viscosity esters to get the desired solvency, it would end up as a very thin oil and burn off easily (think of synthetic two stroke oils). In terms of formulation chemistry, it becomes problematic to achieve both good solvency AND low volatility in the same formulation ....
So the approach Terry is using actually makes a lot of sense, even if it seems like VooDoo engineering ...
