I just purchased a 2023 ELANTRA N… a couple of weeks ago, now I’m ready to change out the brake in a oil at about 1000 miles…(I normally do it at about 400 or 500 miles but I’ve been super busy)… The owners manual says do use 0W 30. But I went to three different parts stores today, Auto Zone, O’Reillys, Advanced Auto. And the only synthetic 0W 30 I could find was one that said it was European spec. What is everybody using. There was a lot of 0W 20 and 5W 30. But I was trying to stay with what the manual recommended, thanks for the help in advance.
