[SIZE=10pt]I don't know, but Prestone still sells Dex-Cool as well as their newer line of Extended Life Coolants. I'll stick with the newer formula even though the main ingredients read the same. Something has changed.[/SIZE]What's strange is that I have a bottle of this too and it has the EXACT same ingredients as my bottle of Prestone Dex-Cool. So, it makes me wonder if the formula has been changed over time.
