Why Does Europe Have Higher Octane Gas?

Octane Rating - RON vs MON vs AKI. Often people ask "Why does the US have such low octane gas at the pumps?" They state this assuming European fuels have a significantly higher octane, when in fact it simply comes down to how we label our fuels. Most countries show the RON, or Research Octane Number. In the US, as well as a few other countries, we show the AKI, or Anti-Knock Index, which is the average of both the RON and MON, or Motor Octane Number.
