I fill up at Sunoco with Octane 94 in all my cars and bike. But I realized that the milage is at least 10%-15% less than 91 Octane (Shell/Esso).

My question is, shouldn't Octane 94 have better milage compared to 91 Octane? Or Octane 94 just makes the engine burn more fuel to get more power?

Which Octane would you use?
