bio-diesel

Not sure if they can help but tallowate in melbourne might have something

Absolutely you cannot just pour it straight in "unmodified"
It needs to be heated up to around 70 degrees so it is a similar viscosity to mineral diesel. Usually this is achieved by using a separate tank for SVO and using a coolant heating coil or heat exchanger in the fuel line. But it must be switched back to mineral diesel before stopping as the cold vege in pump is very likely to destroy your injector pump on startup. Apparently is best in engines with indirect injection.
Other than the viscosity thing it burns like mineral.

That "diesel engineer" should do a bit more homework. DON'T use SVO (straight vegetable oil) without pre-heating it as per fisho64's post. I believe that the critical component is the injection pump, not the combustion method. Rotary pumps will be damaged but some inline pumps can handle it.

Howdy - I have been using SAFF Premium Diesel for about two years now - run an 80 series TOJO manufactured Nov 1997. Their (SAFF) Premium Diesel from what they say is B20 (20% Bio Diesel 80% "normal" Diesel. At one stage I mistakenly used their B100 (100% Bio Diesel) with no ill effects other than a darn good clean out of the system and some dregs in the fuel filter noticed by the service people.
Seems to be good stuff and I shall keep using it as it is LOCAL product as far as I can work out. Have a look on their web site as mentioned already.

Some countries in europe run B20 as standard and I'm pretty sure there'd be a few mercedes vans in those countries...

Really makes you wonder where these num nuts (dealers) get their information from.

I'll say it again (as in all the other Bio Posts) I'm running B100 from a local supplier and have been since the start of this year. I actually put $20 of Dino diesel in on Sunday comming back from a trip down nanup as my 110L of Bio wasn't going to get me home. Man it was weird using a bowser after all this time. And bleep they don't give you much for $20 these days do they!! Less than 15L. I sure was happy to get home and pump in some more Bio. :-)

"but i think Nissan said no to any bio diesel."

some Nissans, Im sure they would prefer you didnt put ANY diesel in!!

Hmmmm
You just couldn't help yourself there, eh? ;-)
Actually, Nissan says is ok as long as it meets our fuel spec, and that means no more than 5%.
I have read somewhere that the main "showstoppers" are actually the injector manufacturers. They claim their products are made to go with petro diesel and generally don't warrant performance/longevity with anything else.

There is a guy on this forum, cant think of his name at the moment, he knows the ins and outs of bio fuels and he has said that you CAN definately run you car in warmer weather with 25 percent of straigth cooking oil. Finely filtered or of course new oil is preferable. Michael

"he has said that you CAN definately run you car in warmer weather with 25 percent of straigth cooking oil."

At great risk of sounding sarcastic, if it has 75% mineral diesel in it, it isnt Straight Vegetable Oil is it?
Yes you can do that, but it does increase the viscosity the more you blend it, and raises the gel point of the fuel. Try putting cooking oil in you fridge and see how much it thickens compared to a sample of diesel.

Yes Fisho, you have me on the way i have worded my post. As for straight, i meant not bio diesel. I guess if this guy uses 25% cooking oil and you havent tried it, i guess he would know and you wouldn't. I will find this guys name and he can set you straight. Michael

yes I have been down that road, done all the research, make bio in the shed when time allows. Bio is not necessarily vege oil. Point is if there is someone telling people to put SVO (pure) in their tanks and drive off, then, well, bad luck for those who listen to him I guess.
Yes you can blend it. But you need to be careful on what you are blending. Some types of vege oil can seperate if car is left standing with a tankful. Result could be disasterous.
Also adding thicker vege oil to diesel will thicken it up somewhat (even at ambient temp) Your pump is calibrated for a certain viscosity, and some types of pump dont like a change. I dont use it as such anymore, I blend bio with mineral instead, or use Gull B20.
