I don't think you'd get anything out of it...

You run the chance of having a missfire with the plugs gapped at .060, maybe not. If the car does not ping on 89 octane fuel use it, if not go back to the 92-93. Do not use more octane than what the engine needs, it will hurt power if you have to much octane.
