Question type: Maintenance & Repair

I have a 1988 porsche with non-ethanol gas in it. What, if anything, do I need to do to prevent any damage when I have to use the newer mixed fuel?
Thanks,
Charles

You can use up to 10% ethanol in most any vehicle, you won't want to go higher than that. You may change to a hotter spark plug or adjust your timing a bit if you notice a pinging/preignition/spark knock.
