Not Ranked
You need to be aware as stated above that even 100 low-lead Avgas still contains gas and one weekend it will ruin your O2 sensor (I speak from experience). I would not be as concerned about legal implications if using AVGAS OFFROAD.
Running higher octane than needed can lower running temps, which is why many people will still run 100+ octane NO LEAD in a late model street car that is being tracked.
