Since we are on the fuel debate, is there any benefits to running leaded petrol? My understanding about the shift to unleaded is that lead additives are not compatible with catalytic converters. My car no longer has cats, so does this mean I can use leaded fuel?

In Australia 98 RON unleaded is readily available, and is all I use in the boxster. I'm just wondering if the lead would somehow help the motor apart from increasing octane. Maybe it lubricates better or something??

Your thoughts are much appreciated.
