You can actually run your 80 on pretty well 100% veg oil with little or no
modification as Jon Wildsmith does. In actual fact Diesel engiens were
originally developed to run on veg oil by Mr Diesel.
The biggest problem with Veg oil is that the glycerene causes waxing that can
block filters, etc, however if you pre-heat the veg oil before feeding it into
the engine you can avoid the problems, although I understand that this isn't
necessary with the 80 series engine.
There is a stack on info on the web about such things, take a look at:
handy forums on the subject.
- a company that does conversion kits so cars can run
on veg oil.
- some good general info.
- the singer Willie Nelson's site on the subject.
As Clive has pointed, whilst running on SVO (straight vegetable oil) may be
cheaper, you should be paying your government the duty on the amount you use,
since in most countries the tax on fuel applies to the fuel that goes into the
vehicle regardless of the type, although I believe that there are different
rates for different types. Having said that I doubt most people running SVO in
their cars admit it to the Chancellor.
One day we might have an enlightened government that will be willing to charge
a significantly reduced tax, but I doubt it.
I personally run 100% Biodiesel made from WVO (Waste Veg Oil) from
although Andrew is looking into producing it from
Oil Seed Rape, etc and is talking to local farmers to sort out a supply source.
