    Only brand/oil I put in my car
    By  THOMAS,  a  Verified Buyer  from  Denver  on  March 21, 2025
    I have a 2022 Elantra N and this is the only stuff I put in it. After a couple of headaches when I bought the car brand new at the hyundai dealership their service team is incompetent. Twice they almost put the wrong weight into my car arguing with me that I was wrong when I told them look at the oil cap uhhhh Ya. So I swore I would do all my maintenance and work to my car myself. Besides bodywork. Car drives smooth and I can tell it likes Amsoil by the way the car feels.
    Bottom Line
    Yes, I would recommend this to a friend.
