The other day while at Auto Zone I bought an anti-freeze called Prestone 5/150 Extend Life, GM DEX-COOL Approved, silicate & phosphate free. Meets Ford WWS-M97844-D, GM62277M, among others. It has a weak orange color. It says to use a 50-50 or 70-30 mix. Is this the same product GM sells as DEX-COOL? If so, it looks like the DEX-COOL product is a little easier to buy, and maybe a little more economical, at about 7.00.gal.
Like new ’95 945 90K, and the red headed stepchild, ’78 245, I beat like a rented mule
