Hi there Gael, I would think the only thing which would get hurt is your wallet.
Its only really highly-tuned cars (with turbos especially), that benefit from higher octane levels.
Its better to use a good, branded fuel, than supermarket petrol, as it contains various additives to keep the engine clear of debris. Although, occasionally using supermarket fuel won't do any harm.
Hope that helps - its quite a subjective topic - am a bit surprised that nobody's jumped in before me!
This job should never be complete - the day I think I've done it all, is the day I resign.
