In particular for a 2025 NX 350h AWD. I just saw an older video that said premium gas was required for the 2nd gen 350h engines. Clicking the youtube link will take you to that part of the video.

For the 2025 350h models my understanding is that premium is recommended but not required (in other words, using non-premium will not void any warranties).

Doing a cost-benefit analysis, would you recommend using premium or non-premium gas?
