Hello just trying to get a suggestion on a coolant for the 2008 Elantra. The manual said Ethylene Glycol Coolant which is no real help. Peak Asian green states that will work on my car. I think the Pentefrost A2 will also work. I was thinking of Zerex asian blue as that was recommended by Napa. Someone posted that Pentefrost A3 whould work where asian blue coolants were called for. But Advanced Auto Parts said that A3 is not for my car. I think my 4th gen Hyundai engine is simalar to the previous 2000 - 2006 Elantra engine so kind of old tech. The additives get confusing. I even looked at Rotella elc and there was the nitrate scare. Any help is appreciated.
