Lower octane?

OK Adam - how are figuring your lower octane makes your car happier? That is flying the face of what Porsche says to do of course, which I'm sure you know. The engine will compensate to a degree for lower octane but that limit is around 96 octane. Are you checking your spark plugs, studying your emissions on a hydrocarbon reader...? Obviously we'd all like to run lower octane and save some money, but if that puppy is pinging it means significant damage to the engine is happening. One of the easiest ways to begin such a process is to look at your plugs running premium and see if they are wet and carbonized.
