The hybrid uses 0w-16. Crazy how thin they make oil nowadays. I buy a few cases to keep in hand as not many places local stock it. YMMV, but if you go that route there are some details called out in owners manual for making sure you run the thin oil.
While we have all the little kids I can’t see is going away from the Toyota sienna with this drivetrain. Avg 33mpg and have done as well as 41mpg on highway trips with flat roads (South Dakota,Wyoming).
