Came off of a new-to-us 2018 Hyundai Sonata with the 2.4 GDI and 37,000 miles, unknown oil. Probably somebody's bulk 5w20. Has less than 1000 miles on it, but didn't have a sticker in it when we bought it, so had no idea of mileage until I pulled it. That being said, it was an ex-rental, and likely got the cheapest maintenance service they could find, and as I prefer full syn, it was coming out anyway. Had a coil spring that you can see in one of the pics, forgot to snap it by itself. Looks decent enough for a low cost filter, if I had to guess based on construction i'd say its a Mannhummelwixolator.
