AntiFreeze tester, propylene vs. ethylene difference

I searched but did not find......

I just came to find that you can't use the same AntiFreeze tester for PROPYLENE glycol based antifreeze (Prestone) as ETHYLENE glycol based antifreeze (PEAK) even though they are both "Green". It has something to do with different specific gravity.

I came across this this past weekend when refilling my cooling system. Checker had Peak AntiFreeze on sale, two 50/50 mix gallons for $10. On the back of the container it said good to -34 F. After refilling my coolant system I check it and only had 3 balls floating with one sllooooowlllyy decending, Roughly -15 F or so but definitely not -34 F. I even stuck the tested in the container to make sure it wasn't being diluted by my system. Got the same 3 and a half balls floating.

So I looked it up and sure enough found that the two won't test the same with the standard testers. Anyone got a Refractometer.....

Anyone have a conversion for the Ball Values?

My testers balls values are: 20 5 -10 -25 -40 (be nice).

Does Heat affect the test value?
and finally: Can you mix Green with Green antifreeze, as I always though you could, even though they are PROPYLENE/ETHYLENE based?

Both companies are now offering products that are compatible with ANY antifreeze/ coolant regardless of color. But what about testers?
