Also it depends on how fast you drive on the highway, nevertheless OEM engine oil viscosity grade for most of Hyundai gasoline sedans is 5W20, so any 0W30 or 5W30 oils with A3 specification is good enough for your car for noise control and highway driving both I know.
I do not recommend you any 0W or 5W40 oils for your car as you could lose more like the fuel-saving and the starting acceleration unless more tha 90$ of daily driving is highway high speed.
정숙성과 고속에 중점이라면 토탈쿼츠 에너지 9000 0w30 써보십시오.0w30치곤 좀 무거운 편이라 초반 스타트나
시내주행에는 보통이지만 고속주행이나 정숙성에서는 정말 좋더군요.같은 아반떼hd 가솔린 차량 타고 다닙니다.
현재는 페트로나스 0w30 넣고 다니는데 쿼츠0w30하곤 별 차이를 못 느끼겠는데 고속에서는 쿼츠가 낫다는 느낌~
