A change in octane won't affect mileage, only performance. You can probably run 89 in the car if available, just don't wring it's neck at every red light.

Negative ghost rider. It won't make the engine any more clean or dirty. It will just be more prone to knock retard which will force the computer to reduce timing and affect horse power.
