I run a 50/50 mix of Veg oil and diesel when it's warm in the summer(bought from supermarket at retail price) in my 1996 Hilux Surf truck. I use
about 60/40 diesel/veg mix when it's colder.
It's a 3.0 Litre beastie, but when using 50/50 veg/diesel mix it's 'carbon footprint' is roughly equal to a 1.5 - 1.6 Litre compact car.
Saves about £15 - 20 for every full tank of fuel too. ($30 -35).
I save about 50p per litre (about a third of the cost of a litre of diesel), for every litre of diesel i replace with veg oil.
BUT..you have to either go for an older model diesel vehicle, or retrofit the fuel pump, and injector set on a more modern vehicle for older
Newer diesels fuel pumps just can't take the extra load involved with pumping thicker veg/diesel mixture..older pumps are more robust and manage
Some people add a fuel pre-heat stage, so that the warmer fuel is thinner and so will pump and flow through the injectors more easily, or they simply
add some other ingredients like a gallon of white spirit, or a couple of litres of unleaded petrol (gas for yanks ;-)) per full tank, or a bottle of
diesel treatment additive, to thin down the veg/diesel mix.
I'm happy with the very slight engine performance drop, in exchange for a 30% saving in fuel costs, but engine emissions and harmful gases being
released from the car, drops very heavily..so it's good environmentally as well as a money saver.
But in a SHTF situation, while you'd be able to use the entire truck as a diesel generator (run the truck static and attach a lead to the battery
while running the engine), sooner or later, all veg oil and diesel will be harder to find than rocking horse poo..so any generator that relies on
hydrocarbons is going to get useless quite quickly i reckon.
A better option for power generation in a SHTF scenario, would be one of those 'biolite' (think that's the name) camp stove generators, but scaled
right up to provide a useful amount of power.
These use fire/combustion of wood, straw, twigs, hay/dried grasses, newspaper/cardboard, anything able to make a fire as fuel to generate heat for
cooking and heating water and also running a small heat - electricity generator.
You'd need a larger version than is yet available, but the principle should be the same as the small one out now.
Or perhaps use the same fuel. but rig up some kind of steam engine attached to an electrical generator.
These four young girls, have come up with a device that require external power input to work...not a great solution to lack of electricity, if you
need electricity to make it generate imo.
