Did some searching but I’m still not sure. My mom has a 2016 Hyundai Sonata 2.4 non turbo. Owned since new, and always got Valvoline syn blend 5w20. Still under the 10/100k warranty, has 80 something thousand miles. Has always consumed about a quart over an OCI. Was taking with my dad about it, and I couldn’t definitively find if this car was ever affected by the bad engines, and/or the TSB recommending thicker oil. From what I can see, it’s not, but it looks like later years of this engine in other vehicles is.
