...it shows, in the right column, the current Federal (EPA) "test fuel" requirements. Note that AKI is always slightly less than the RON number, hence AKI = 91 octane, from RON = 93 octane.
That's a proposal for one standardized test fuel between the CARB and EPA. They are suggesting only testing with Premium grades and use 10% Ethanol.

I don't see how that means they only test with premium.
