I have a Peugeot 405 diesel about 9 years old, with 120k on the clock. I hear very often it's OK to put straight vegetable oil into the fuel tank, and drive with no problems.
Has anybody done this so far, if so, how did the engine run ? and was it better to mix diesel and veggie oil or to alternate a tank of diesel with veggie oil ? It appears that mixing 50/50 might cut down on engine deposits from the veggie oil ?
It might smell like a mobile fish and chip shop but it's got to be cheaper 🙂

It's also pretty easy to make bio-diesel yourself. A friend of mine does it. Also, the farmers here are increasingly interested, because they can grow the sunflowers, make their own oil and bypass government taxes on fuel. I would think that used oil would probably need to be filtered. Your only other problem would be storage

I have seen bio-diesel advertised and talk of adding a drop of white spirit to the neat oil, but it seems from a lot of people, you can simply put clean fresh veggie oil straight in ! thanks for the tip about storage to Buffalobill, I guess it degrades over time or thickens up ?

Biodiesel is definitely the way to go over straight veggie oil. It doesnt leave deposits but it is a very good solvent and tends to break loose old deposits from the regular fuel. For this reason, you don't want to start off with it. Ease your way in with B10 (10%Biodiesel 90% regular fuel), then go up to B20 or B25 after a week or so and gradually work you way up to B100 (100% Biodiesel) so as to avoid engine clogs. Be careful if you live in a cold climate though, you'll have trouble getting started on cold mornings or might not be able to at all. A heated garage is the best solution so far although they are working on additives to keep it starting in the cold.

Yes, you can put in straight veggie oil, a diesel engine will burn pretty much anything since it works by compression. Biodiesel is a better alternative though.

thanks Umbrageofsnow, useful tips there, however i don't believe i have ever seen biofuel for sale anywhere !
What about a tank of diesel/veggie oil/diesel etc ? is that a good compromise ?

Actually, now that I think about it, as good as the compression in most diesel engines is, straight vegetable oil might not be the best. If you are going to use oil, make sure to filter it, using it fresh is probably too expensive. There aren't, to my knowledge, any large scale biodiesel manufactures for more than a small area. You might want to check with the chemistry department at any colleges or universities around where you live to see if anyone there is making or researching it. If not, making your own isn't that difficult. Check out this site for good procedures for making your own and for better information on straight veggie oil.
