I'm buying oil for my 2021 Corolla and keep seeing both 0W-16 and 0W-20 listed for the 2020–2022 model years. Does the correct grade depend on which engine the car has? If I can't find 0W-16 locally, is 0W-20 an acceptable substitute, or is 0W-16 required?
Also, how many quarts does it take for an oil change that includes a new filter?
