green antifreeze

[md21722]

Looking for some technical opinions on coolant.

The local Auto Zone has Conventional Green (not universal) coolant. The local farm and ranch stores have old stock Zerex Conventional Green, Durex Conventional Green, and Polar Conventional Green. They are all labeled "low silicate" and not universal (like Prestone). I assume they are the old IAT formula. Is there any reason to buy one over the other? Auto Zone wants $11.99 a gallon and the farm and ranch stores are selling the Zerex, Durex, and Polar for $9.49.

That universal fluid is similar to dexcool

I would go with auto zone green stuff and Diluted water as jeep recommends. Dexcool requires frequent maintenance, and I wouldn't put it in a old system that wasn't designed for it either
