This is what I’m sick of. People assuming things that they have nothing to back it up with. I never say that higher octane is better for the yaris engine, just show me some proof that is not if you're going to make that claim. I did show where some would say it is better but did not state my opinion. If you’re going state your opinion then show me some facts.

I spent half my life working in the labs and offices of the world largest gasoline and oil companies here in Houston, would love to read some facts and not opinions.
