I've had several newer GDI engines and most recently a 2017 Pathfinder. After 6k miles of full synthetic oil with an OEM filter, the oil was black and smelled terrible. It's SO strong. I had a 2017 SantaFe V6 before and had the same thing. Same with a Sonata I4. Hyundai says to change the oil every 3k and massive oil consumption is normal, hence why I left the brand after my 2017 drank 5qts in 2k miles. (That was 'normal'). My VVT engines or anything that is port-injected the oil is decent looking and smells mostly like oil after at least 6k.
Should I be safe and change my Nissans oil every 3k? These motors seem picky.
