Peter,
I'm surprised your
forum search didn't show up my contributions on this topic before.
Yes it is possible.
There are a wealth of good links with a few starting points being:
www.ravenfamily.org/andyg/vegoil.htm
www.greasecar.com/
Site Link
www.frybrid.com/
www.biofuelsforum.com/ go to the WVO section
Adding brand new
supermarket vegetable oil - available on special at my local
supermarket for $1 litre - at a blend of up to 25% oil requires no modification, no concern for clogged injectors or rings, will remove the diesel smell from you exhaust, extend your use of fossil fuels, give you a great talking point, run your engine quieter, minimise the black smoke. You will also be breaking ATO laws by blending an excisable fuel and a non excisable fuel. To get around the tax laws, you run a two tank system where you start up and shut down on dino diesel and when the engine is warm, you switch to heated full strength vege oil.
A diesel can run 100% vege oil new or used without problem as long as it is viscous enough to be injected properly otherwise you may/will have problems with coking injectors and rings. You reduce the viscosity by either heat - at 70°C canola oil reaches a viscosity similar to diesel - or by thinning it.
You can heat it either electrically, or the favoured method of using a heat exchanger off the coolant system. To thin it people use dino diesel, kerosene and in the US they use unleaded.
Adding even a few litres to a tank full of dino diesel will increase the lubricosity of the dino diesel substantially for the benefit of your pump.
Filtering is critical. Vege oil users can buy 5 micron sock type filters that are adequate.
Supermarket oil does not need filtering, just pour it in.
Heating, blending etc., can be avoided as per the above post, by converting the vege oil to biodiesel, which several
forum users are reporting on.
Using vege oil, new or used, is NOT biodiesel.
Some diesels, notably rotary Lucas pumps are not suited to vege oil.
The jury is out as far as I know on VO for high pressure common rail engines. It would simply be a matter of viscosity through the pump and injectors.
Caveat emptor. Do your own research. Try it once with new
supermarket oil. It's only kinky the first time.
Regards
Tim

I think when we all get a clear handle on the do's and dont's, revenge may follow on the oil companies!!!

Tim,
thanks for the info. i have read many of your replies on biodiesel. they are very informative and a great read.
just couldn't find the one specifically on my question. i put it down to my lack of search skills.
i read how to make biodiesel. i read that i can run SVO from a separate tank. i just didnt read if i could blend dino with svo. the info you supplied is as usual very good and the links are great. oh and a special mention to saurus. the link almost worked.
all there is to do now is give the mix a
test run. might even make my own proper biodiesel. hopefully the old injector pump wont blow the still original seals as a result. surprised it hasnt already with the low sulfur diesel. still i put some lucas or moreys additive in every so often so maybe that is doing as they claim and keeping the seals from leaking.

Thanks for the
feedback Peter, you're probably right that I hadn't previously answered your specific question, no worries.
This isn't the best
forum to be getting the technical tips on vege oil and bioD, it's good for lot's of things, but there are much more comprehensive sites out there that are better, and with fewer naysayers, for this stuff.
One of the problems with VO and even BioD made in the backyard is the legal aspect. it's all a bit underground - I've heard about this bloke that ...., so as to avoid undue attention from the ATO. Bit sad really.
One of the things I've learnt with the WA Renewable Fuels Association meetings, www.shortcircuit.com.au/warfa/warfa.htm are the lubricosity benefits to IP's by adding a couple of litres of new oil to each tank. Not as anything special to save the environment, but as an additive to increase the lubricosity of diesel. Now I don't know why the seals might be leaking, but I'd be betting 2 litres of vege oil will be a lot cheaper than anything branded Lucas or Morey's, and just may have similar benefits.
Personally, I can't see myself making bioD. Not enough room at
home, too many dangerous chemicals. I failed Chem at school, it's all a bit spooky to me. I'll be buying bioD when it's available, but making it.... not for me. Each to their own.
All the best in your journey.
Tim
