I'm new to Posches but my other vehicles built within the past 15 years all have knock sensors that detect motor knock and adjust the ignition timing as needed to prevent it. Can anybody confirm whether or not Porsches have knock sensors? Does the 2000 S model like the one I bought a month ago have them?
I doubt I would use regular gas anyway but it would be nice to know whether the engine can actually be damaged on low octane fuel. I've used regular in my Corvette and couldn't hear any knock or feel any power loss but I decided high test would only cost me about $100 a year and there was no point to the cheaper gas.
