Octane rating has no bearing on the quality of the fuel lmao. It just runs better in engines that are designed to run it.
Octane rating does not relate directly to the power output or the energy content of the fuel per unit mass or volume, but simply indicates the resistance to auto-ignition under pressure without a spark.
Some engines will adjust spark advance by using the knock sensor, and when using a higher octane gas, will be more efficient.
The gas is not more power dense, but it gets used more efficiently. If your car doesn’t, then it’s not better to use higher octane gas.

Yes, thanks. That’s exactly what I said, and I agree with you completely
