| There has been much debate as to the suitability
of using vegetable oil in diesel engines and a considerable amount of
confusion as to whether these oils can cause damage to engines. This
database will help us decide which engines can be run successfully by
looking at actual use on the road, as opposed to laboratory tests. We
would like to identify vehicles that run particularly well by rigourous
statistical analysis, which will be available free to all, on this page.
Please feel free to add your own experiences of using
vegetable or animal oils, whether good or bad, by clicking on the 'add
new' text on the left. You may also search for your vehicle if you are
considering using one of these fuels to see what success people have
Please note, do not add entries on this database for
biodiesel (methyl ester of fatty acid triglyceride) - only straight vegetable
oil (SVO) and straight animal oil.
For those who want to conribute to the database, we have created a password protected data entry system to
ensure that we get the best results. The password is FREE, all
you need to do is send an email to : Fuels

Some initial conclusions: Lucas pumps are not performing well on high doses of vegetable oil. This pump should be avoided. Other problem areas are related to computer control systems (TDi, HDi, CDi etc.)which have an array of sensors reading temperature, flow rates etc. These sensors seem to get confused by the thick oil and instruct the fuel system to go into safe mode, resulting in loss of power. Some sensors seem to get completely destroyed by the oil, resulting in an expensive replacement pump. Another problem is with electric lift pumps which operate prior to the main pump; if these pumps fail the main pump can run dry and fail as well. Also, it seems that people are not very forthcoming if their vehicles have failed so we are more likely to here about the success stories than the failiures. One of the objectives of this database is to identify vehicles that have problems so that people need not repeat the same mistakes.
