Is Australian super auto fuel a leaded fuel?
If you are using the Rotax 912 you should not use a leaded fuel if you can
as easily use unleaded.
If your super auto is unleaded then you may have serious problems ahead. In
Europe Octane levels of super unleaded fuels are boosted with volitiles that
you would not want in an aero fuel. They are far more prone to vaporisation
than normal fuels and not suitable for the varying pressure environment of
an aircraft.
That's as I understand it but I am always ready to be told I am wrong.
