I provide some maintenance for Old World's ethylene glycol unit. I have no idea where they get their oil, but I know that they make Herculiner roll on bed liners as well as Peak antifreeze and some other stuff. I know they treat the employees well, not sure how good they are at making oil. If I run across one of the management people I'll ask about the oil.

Viscometric properties for Peak's 5W30 formula are superior to that of Pennzoil conventional. Both 5W30 formulas share a pour point of -39C, but Peak 5W30 has a higher viscosity index and better performance in the NOACK Volatility. From this limited data, I'd say it's a pretty decent oil, and if you can find it, their 5W20 formula looks pretty good too.

You can check out published data for their other forumlas here .
