It's 95. The knock sensor doesn't make it safe to run a lower octane fuel. It's meant to prevent engine damage in case someone does put in lower octane petrol. At 95 octane, the engine runs as normal. If the petrol quality dipped, the knock sensor would detect it and retard the ignition and cam timings. There is a limit as to how much it can retard the timing. Once you exceed that limit, it's ping ping city.
