So in doing some research the biggest difference is pink is bio-degradable(safe for the marine environment). Preston which is green also makes anti-freeze comparable with the pink anti-freeze. You can actually mix the two.

The biggest difference is price. The Pink OEM is twice as much as the Preston! Looks like I am going green!!!
