I think most of us are aware that there can be issues running Ethanol fuels in olders cars, but does anyone know whether the P100 has enough Ethanol in it to matter?

I have a Gen1 Liberty with a JDM Ecu, which runs rich and is tuned for 100RON fuels. I want to use the P100 if possible, and basically want to know if the % of Ethanol is actually going to eat things in my fuel system? We all know we can't just go and run E85, but what about P100?
