What's keeping the natural viscosity of processed oils - mineral oils, from becoming any higher than they are? Cost aside, and I suppose market necessity as well...what's the snag? Group 3 with cracking, cat. dewaxing, hydrogen saturation...don't quite have a "back hand" knowledge of it all, but none the less curious at better understanding the limiting factors. Thanks in advance for any contributions.
