I have a Hyundai Sonata with the 2.4 4 cylinder engine and I was wondering what oil Hyundai motors seem to like the best. I usually do the 3k OIl change and most of my trips are 5-10 miles during the week with Highway driving on the weekends. I use Valvoline Nextgen 5w20 in it now since I got some for 10.50 for 5qts with a coupon. I was thinking about going down to a 0w20 though since winters in Northern IL get pretty chilly and my drives are so short. What do Hyundai motors typically do best with. I heard the manual calls for QS but I dont really care for them but if its best for my car then I will use it. Thanks!
