What is "100-LL" Fuel?

The town next to mine, Tavares Florida has redone their lakefront, and developed a SeaPlane landing area and docking area. Went there yesterday, and the whole area is beautiful. Just a few boats tied up plus a Seaplane also tied up. Walked out on the docks and saw they have two gas pumps. One says
93 Octane which I assume is for boats, and the other says
100-LL which I assume is for aircraft. Someone else walking by thought it may mean it is 100 Octane Low Lead, and that it may be dyed blue, but he was not sure. Anyone know what 100-LL stands for?

Yes, its for Aircraft and it is leaded. Piston aircraft are still mostly running leaded.

Low Lead is correct.
A general purpose light aircraft gasoline.

OK, thanks. I was surprised that the price was "only" $4.16 a gallon. I thought av gas would be over $5.00 a gallon.

Like anything, it's a function of supply cost and how much profit the FBO wants. It's between $3.90 and $4.50 locally. Big push to get rid of it from the tree huggers because of the minimal amount of lead in it but there's big resistance in the General Aviation industry for many reasons. One thing they definitely don't want is anything to do with ethanol. Water in gas is not good, especially above ground level.
