thanks Kelly, plenty to think about.

I have been looking at biodiesel as it is an interesting topic which I thought might have an application to our needs. I haven't found any place locally that sells it yet but the process to make is not too complicated. However, having to "cook" up a batch of fuel to go flying seems like an awful lot of work. Still, the process is interesting and the results might just make it worthwhile.

I had never thought of mixing something like the Coleman type fuels (Naptha ?) with kersoene. I will have to give that try.

George:

Mercury No. 6 - never heard of that one, maybe someone can uncover some details on that one.

I did run across this interesting bit on fuel for F2C Team Racing. Seems many years ago the Russians where using Tetra Ethyl Lead in their Team race fuels which allowed them to run higher compression. Some enterprising fliers found a substitue in ferrocene, (dicyclopentadienyl iron),

Andy has been pretty quiet of late. I wonder what he has been up to in his testing.
