2019 Toyota Corolla Hatchback XSE, North American Owners Manual recommends a 0W-16 or 0W-20 if 16 is not available. I found it very interesting that Toyota Japan and Toyota Austrailia recommend such a wide range of oil weights for the exact same model and engine combination.
Why wouldn't Toyota NA use the same broad spectrum of oil recommendations listed for Toyota Japan/Australia? MPG regulations?
This just goes to show that many engines can run nearly any weight of engine oil without catrosophic failures.
Personally after seeing the Australian owners manual oil recommendations I would feel comfortable running any oil viscosity listed here in the states.
