Seems to me that the 100 octane "blue" aviation fuel was leaded, but I
don't know about 100LL.


The 100LL is leaded gas and is dyed blue.


That's what I thought. So, 100LL is the same as 100 blue.

I heard that some of the newer engines were designed to run on 100 octane
unleaded, but I've never seen one.
