OK, so now I sit here and wonder how long till Andy fires up that Bio-homebrew, because, this my friends
is the big jump. A single component fuel that doesn't smell bad, not that's a hell of an idea. Of
course many questions remain, 1. Will olive oil polymerize to become a true synthetic castor oil (castor
as you remember is the only oil that becomes thicker when heated) 2. Will the Biodiesel process ruin
the olive/synthetic castor and cause it to loose it's unique properties. 3. Will the new oil both burn
and lubricate. And finally what will it take to make it work.
This is a dream it doesn't exist in our world today for any internal combustion engine.
A single component fuel will never happen. Castor does not get thicker when heated(take a bottle and put it in the freezer). At a certain temperature castor polymerizes into a solid. Oil won't burn in our engines. Oil which has been esterified into fuel(the biodiesel process) will not lubricate the engine. It might be possible if we use anti friciton bearings on all rotating parts in the engine. Biodiesel doesn't have the properties to burn well in our engines anyway.
Single component fuel will only work if we have lube oil from another source, be it crankcase or oil injection as in motorcycle two stokes. Biodiesel could burn if we had high enough compression ratios. We simply don't have engines capable of burning straight B100 or any other oil.
There is no such thing as synthetic castor oil. Synthetic describes many things. Germany synthesized virtually all of their oils and fuels from natural gas during WWII.
The kerosene smell can be removed by washing with hair shampoo.
Treven, two stroke oil actually spends a certain amount of time in the engine. The only portion that gets replaced every stroke is the portion that doesn't settle on engine components. The rest migrates to the exhaust much more slowly.

Model four strokes do not have crankcase oil and have plenty of lubrication just from what gets past the piston ring. You wouldn't want to start one dry, but you wouldn't do that with any engine.
