Ki-43-II WEP vs A6M5 Military Power.

What octane fuel did Japan use during the war?

IJN used 92 octane from start of war.
but, IJA used 87 octane in start of war.
(Ki43-I was tested by 87 octane.)
but, it was changed at 1942.
It's a ok that you think many IJA planes used 92 octane.

If IJA could use 100 octane, it was a exactly Ki84 got over 660km/h...
