Toyota's new 2.5L has proved itself

Good to know.

What about other fluids / maintenance? ATF change interval, etc?

Thanks for sharing.
Welcome. ATF every 60k, engine and inverter coolant every 60k, factory brakes still, spark plugs at 150k(They didn't look bad), Brake fluid once at 80k, hybrid battery air filter cleaned every month and replaced every 6 months, engine air filter twice a year. I buy the parts online so that helps. Top Tier gas and some Chevron Techron once in a while. And frequent driving the car as if I stole it lol. This Toyota eCVT is also pretty bulletproof.
No front diff fluid because it doesn't have it, and no alternator because the hybrid battery does that job. Still get 37-40 mpg. 2021 Sienna
 
Saw a UOA of this engine here with HPL 0w30 and it looked better than my numbers. Either HPL is legit or 30 grade did the trick. It is time for me to switch to at least 0w-20
 
OP...have you used 0W-16 oil mostly? always? sometimes? please elaborate.

Glad to see this. I have a 2023 Rav4..low miles so far. It is a fairly complex engine.
 
not always but depending on job location, building construction my not stock 300 tq 2001 jetta1.8T seen a thou weekly traded at 200 thou running great!! oil changed every 10 thou, used amsoil 10-30 until i was unsure of its formulation then switched to Redline. now driving a 2001 TT 225 in nice weather using redline 15-50, my 11 frontier just switched to 10-30 HPL passenger car oil + seeing less consumption than typical group III fake synthetics!! the TT + Jetta both only held just over 4 qts!!
