After reading through posts, I found that the Zerox G05 HOAT coolant is the one to use unless you go to the dealer? I saw it at NAPA for $14/gallon.
Valvoline.com > Products > Antifreeze Radiator Products > Antifreeze > Zerex G-05® Antifreeze / Coolant
Are there any other brands that are certain to meet the HOAT spec?
Thanks, James
