They honestly should of just kept the same exact motor and just improved other aspects of the car like wind buffering, little cosmetic stuff, and etc. Toyota basically just introduced new big headaches for 2021....
I am sure the thicker oil on the 2021 will fix the oil consumption issue. So no need to worry about it or for a new motor.
I was just joking around. Trying to lighten the mood. You don’t know how much crap we 2020 owners got from 2021 prospective buyers back in Feb of 2020..... :(
