Cooking oil instead of Deisel

go to google - "vegetable oil diesel" search
There's loads :-)

Look in the "Engines" history and my Pug 106 threads will become apparent. I sheared the injector pump driveshaft. (Viscosity<>1/T) and at cold temperatures it loads the hell out of the pump. If you dilute it with kerosene (central heating oil) until the right low temperature viscosity is reached, it should be fine. They do stink though 
You also have to bugger about with the injector timing a tad, retard it until the clatter on accelleration stops. It clatters more and smokes when you cane it 
I ran everything from multigrade to olive oil. Whatever I could get my hands on. If you've got some kids at school, see if they can borrow a "U-Tube" viscometer as well as a decent thermometer/stopwatch, do your own viscosity comparisons with diesel. Kerosene is also bloody cheap.
NB:- If you get caught with a tankful and a few Gerrycans, that's all you have to prove the duty for. Pay in advance. No evidence=no penalty!

OK, Listen up once and listen up hard!
Used cooking oil comes with filth in it, water, etc, etc. The molecules look like "E"s, in order to solve the viscosity problems, make the fuel approximate proper diesel, it is necessary to bust the E's up into 3xI's if you're with me. So, this is achieved by chemical means by Sodium Methoxide NaOCH3 (made from methanol and caustic soda) this is aqueous (dissolved in water) agitation of the used oil with this busts the E's into I's and the resulting change of properties of the solution cause the crap/water to separate into the aqueous phase (watery crap). The resulting stuff is as good as diesel and carries virtually none of the vices of cooking oil. BUT the reaction is tedious merely filtering dirty oil is not enough. Making sodium methoxide is a mess and working out the right amounts is a bit tedious. Incomplete separation (takes time) would result in surplus crap including NaOH alkali getting into the fuel system-not a good idea.
That's about as concise as I can be.
