Not really, most cars when they start to knock retard timing.
Turbo and performance cars have high ignition advance and so need high octane fuel.
High octane fuel in a regular car is pointless, its based on something called a driveability index. High octane fuel in a regular car might allow the engine to self-advance its timing a little but no stock ECU will advance the timing very far. Any difference is likely down to premium gas often having no ethanol in it.
