DEXCOOL or equivlent!! DO NOT use the green ethylene glycol OR propylene glycol!!!!!

You need Organic Acid Technology (OAT) which is a Long Life Coolant (LLC) / Extended Life Coolant (ELC) widely used in Europe before its introduction in North America. OAT is usually EG. The generally recommended replacement interval is five years or 150,000 miles.

DEXCOOL was TEXACO brand but there are other brands that use OAT formula that will work.

You can also get Dexcool under the Prestone brand. That's what I used.
