Here we go again....
I used to believe that. But my engine knocks at WOT above 4k rpm with 87
octane (Unocal or Chevron). I think it has to do with the oxygenated gas
here in California. I now use 89 and the knocking is gone. I guess I can go
back to 87 if I drive it like a grandma.

I don't mean to start a war here, but I think you're crazy
for using
anything higher than 87 octane. Just my opinion.
