I have a genesis coupe I bought a couple years ago and have been using 5w-30 havoline pro ds since I've owned it. I admittedly only put about 6k miles a year on the car 70% highway and maybe 30% city. When I do drive the car I tend to drive "spirited". The requirements are API service SM, ILSAC GF-4, ACEA A5 or above. All comments appreciated.
