Hi, I run a Gen3 3300A in the UK. Given a choice between 100LL and 91UL (unleaded avgas), which would be preferable for the engine?
Thanks.

91UL would be the best choice. The lead in 100LL leaves a lot of residue inside the combustion chamber and sludge in the oil.
For more information about fuels in jabiru engines/aircraft have a look at JSL007-7 Alcohol Lead Compression Ratio Fuel Guidance (jabiru website) It doesn't specifically talk about 91UL but covers criteria of suitable fuels.
