HOAT, is not the Brand of antifreeze, but rather the type, (G-05).
Any of your auto parts stores ( AutoZone, O'Reily's, Pep-Boy's, Wal-Mart, they all carry it).
But there are several different Brands of it available. As long as it is HOAT, then they will all intermix. But OAT is a different product, that will not mix with your antifreeze, so don't use it........:nonono::nonono::nonono:
