Specs
Zerex? Asian Vehicle Antifreeze/Coolant meets the following specifications: Hyundai/Kia MS 591-08, Mitsubishi ES-64217, JIS K 2234-1994, ASTM D3306, ASTM D4985, Ford WSS-M97B55-A, and recommended for Toyota/Lexus/Scion, Honda/Acura, Nissan/Infiniti, Subaru, Mazda and other Asian brands
Paying $10 extra for an OEM coolant is not the part that really bothers me. The major hassle is getting over to the dealer. It's not like there is a Toyota, or Honda dealer right down the road from me. NAPA is really convenient for me. We have an account there, it is minutes away, and they deliver.
