On the last 4K OCI before I sold my Pathfinder, I switched to 5W30 and the oil did not get black. It was dark but not black like it was with 0W20 after only 2K.

Yep. I've been using synthetic 5w30 on mine since it's first OCI and will stick with it. I've read of 4 severe sludging issues now on the VQ35DD and at disturbing low mileage with record of oil changes!

My 2019 Infiniti Qx60 has 53,000km (former rental) of which 6,200 is from me since late July, I have a hard time getting a solid oil dipstick reading with the VQ35DD, but I don't see any darkness of the Pennzoil platinum 0w20 that I put in on day 2 of my ownership.
