Tec A says that high octane fuel is harder to ignite than lower octane. Tec B says that using high octane fuel in an engine designed for lower octane will produce better fuel economy and power. Who is correct?
To my understanding higher octane fuel has a higher detonation point, so you compress it more, which will result in more power. Also yes higher octane fuel in a car expecting lower should get better gas mileage and efficiency.
