You should have seen my face when I started to pour some out to mix it down...I was like hey, wtf is this!? The color didn't look quite right and I had to grab a bottle from my stash that I had bought 2 yrs ago. I compared both and the green was too light colored, it was close but not bright enough or dense enough....makes no sense right! But I could see it as soon as I poured some out.

I had both bottles side by side and went down the labels on the backs. The tip off was the real silicated stuff says "Do Not Add to DEXCOOL" The new stuff didn't have that on the label and it didn't have "contains silicates". The part numbers were the same though.

Carquest sells an appropriate formula as well, FYI.

I used the EVANS propylene glycol coolant for about five years. The reasoning? No water = no corrosion.
It's touted as effective in race cars like pro stockers that may have hot spots in the combustion chamber at 14 to 1 compression.
I thought it would bring the coolant temps down, It didn't. So now I'm back to the green stuff.
