With regards fuels..Many years experence in the sector etc...
Diesel and Kerosene / Paraffin are similar fuels. Yes it is true that high usage of Kero in the tank may cause engine problems long term but for urgent use then a tank of kero is fine although it will run hotter. Mixing 1 Part Kero to 1 Part Diesel may make the tank up. Slightly less power from Kero. With regards Veg Oil . It needs to be clean and of good grade and not stored with moisture in it. Run off the top layer and use that. Veg oil will thicken when cold and cause waxing problems but again it can be mixed ok especially with diesel or kerosene. A mix could include 1 Part Veg, 1 Part Kerosene, 2 Parts Diesel. That may bulk up the tank slightly and enable you to get things done ! Jet A-1 is the same as Kerosene with aviation additives and is of a higher quality than Kerosene. In cold climates Jet A-1 or Kerosene can be added to Diesel to help cold starts and in extreme cold (-12 and below) Petrol (Gasoline, Petroleum Distillate) can be added to diesel to thin it out a little. No more than 10% added to the full tank though. The older the diesel engine the more versatile it is and the more fuels it will burn readily.....
Tim, vegetable oil freezes BEFORE diesel, which is a mixture of different hydrocarbons. See what Wiki has to say: http://en.wikipedia.org/wiki/Vegetable_oil_fuel#Temperature_effects

Thanks, Tim. Yes, vegetable oil also freezes. All hydrocarbons do so, in stages and at different temperatures. Information is available online. For example: http://www.zyra.co.uk/freezing-diesel.htm

I believe adding paraffin works, but don't use too much as it dilutes the lubricating effect of the diesel.
I wonder if vegetable oil freezes? I run my diesel car on that.
