[QUOTE="speedwell68, post: 10773, member: 78"] I had a bit of a theory on all of this, only a theory. A VW aircooled is designed to run on 91 octane fuel, so they ignition is timed accordingly. So as we are running on 95 octane fuel is it possible to advance the ignition slightly and gain more power and economy. Would you be able to advance it slightly further if you used 97 octane super unleaded? In theory a greater advance curve will make the engine run slightly cooler too. [/QUOTE]
