Anti-Freeze

I picked up what I thought was 8 gallons of pre-mixed anti-freeze from a Cummions dealer in preparation for my 100K maintenance. When I got home, I found that I actually had:
- 4 Gallons of Propylene Glycol Concentrate (which = 8 gallons of anti-freeze)
- 4 Gallons of Ethylene Glycol 50/50 Premix
Questions:
1. Is there a preference for Propylene Glycol vs. Ethylene Glycol?
2. Are Propylene Glycol and Ethylene Glycol compatable?
