I use 0w for the first start on cold mornings (40F or colder), as it will circulate faster, and better, and that translates into more protection during the first start of every cold morning, and it is at that instance when 90% of engine wear happens.

Wrong!! 5W-20 is NOT the same as 0W-20, and Toyota is aware of it, that's why they say 5W-20 is okay for the Yaris but 0W-20 is NOT okay for the Yaris. Can't believe you're too dense to understand something that simple.

Rearrange the TSB to fit your needs all you want, and make all the excuses you want, but it's gonna be tuff convincing the Toyota service department how wrong they are if they ever question you for using a viscosity that is listed right on the TSB as a viscosity to not be used in the Yaris NZ 1.5
