Do GM cars have to have DEX-COOL antifreeze. I just don't understand the difference. Please help on this one. I mixed antifreezes without knowing and they gelled up in the system and now I have to do a flush. Does my 98 Cavi have to have DEX-COOL or can i save a few bucks and get regular antifreeze?
Thanks,Tim
