I wouldn't use a tankful of 100 Octane on any car unless you have special fuel/timing mapping for it. This would be a waste of money. I don't think our cars fuel mapping can adjust to that level of Octane. Maybe 94-95 octane it would be able to adjust and provide minimal result and better response from the engine.
