This is a big subject and something I've been looking into for use now, rather than SHTF. As far as I'm concerned in the UK and Europe with diesel
being around £1.45 ($3) per litre, the S has already HTF!
Easiest in my mind would be to buy an old diesel car or pickup which is not direct line injection. Older diesels had a chamber before the engine which
heated the fuel mix before combustion which prevents problems with alternative fuels waxing up and gumming up the engine. Even still I would install a
filter pre-fuel pump that can be bolted on and off quickly and replaced. Not sure what to use as a filter, but its better to lose suction once every
few months and have to ponce around unbolting and cleaning the filter out than it is to have to do a complete engine strip down.
Veg oil will work in some older engines, straight (SVO) but waste oil (WVO) will need to be drained and chemically cleaned before use. Both veg oils
do not like the cold very much so you could consider an additional preheat valve on the fuel line or simply mix up something with the oil to give it
extra oomph and a lower waxing temperature (a gallon of petrol or standard dino in the tank with it.)
Another way around the waxing issue is to install a twin-tank system on your vehicle so that once the engine is running hot, the veg oil will not gum
up in the engine and will create a more complete burn.
If you live in a hot climate you will likely not have any problems running an older diesel on veg oil without any kind of contraptions added, but
those of us in colder climates will have to take all this into consideration.
There is also another easier way, kerosine. Kerosine is almost identical to diesel except it hasn't got the lubrication qualities that standard diesel
has. I know someone who was running a fairly new Ford Ranger on kerosine (quite illegally obviously) and was mixing a part engine oil to the mix to
stop it stripping the engine to pieces. I've been meaning to get down there and ask him what the mixture is, next time I'm around the area I will and
I'll post the findings. I think it was something like 1:40 oil to kerosine, but this is a complete guess, don't take my word for it just yet.
Sort of cars your looking for include these:
Old Citroen diesels.
Stay away from anything with a more modern engine. Fords are a big no-no, I'm surprised the Ranger ran OK on kerosine but then again its got a Mazda
lump in it. I've currently got two diesel fords on the drive and they are no good for experimenting on, lol.
