Bio Desiel

[Kevaclone]

My sisters husband has been making bio diesel from chip oil for about 2-3 years now.....a couple of his early batches were not real flash... but he seems to have the game well sused now...... but you do have to be attentive.
His navara seems to be running very nicely on it.

I've been thru Big Doug's "bio diesel plant"(in his back shed) ( at length ) and it isnt rocket science, but I can see where consistency problems can come from

I noted that the bloke on dirty jobs was not washing his product....so he may have exccess byproducts in his fuel.

One bug benifit that has bee tested from a bio blend is the increase in lubricity.....hands down over any other additive on the market for lubricity.


Am I going to run it in mine....um don't think so.

cheers

Yet I've seen the results of damaged pumps where the Bio fuel has worn out pumps due to it having lower lubricity than diesel. Pump repairer suggested a mix of no less that 25% diesel in the Vege Oil

One big benefit that has been tested from a bio blend is the increase in lubricity.....hands down over any other additive on the market for lubricity is a correct statement, I have read the test results a 5% blend of Biodiesel in diesel was the best and cheapest way of increasing its lubricity of several of the biggest commercial products that have been put out there trying to get some lubricity back into diesel after the removal of sulphur

just had the old mans injector pump repaired and the specialist repairer blamed the bio, no way would he run it in any of his cars, he has seen it destroy motors. didin't matter that the pump was stuffed before Bio was used so we just nod and agree

There are heaps of so called specilasts who are prepared to blame biodiesel ( or whatever) for all sorts of things..... but I ask where is the proof.

How can they ligitemately prove that the bio has caused the problem.

Sure there is some dodgy Bio Diesel about.

But all these guys are going to know is they have a worn or buggered item and it has been running bio diesel...... they know nothing of the history or the true causes.

What is most likley is that the item was on the way out and the bio has stripped all the gum and rubbish, left behind from the pertolium waste product we call pump diesel.

If the seals were the older materials....the modern pump diesel probaly would have killed it first.

Lots of these guys, simply wont hear of any alternative product or additive of any discription.

Even in my own family.....there is a disagrement...... my sisters husband quite cherrfully makes and uses biodiesel....... but my brother wont use any sort of additive in his vehicles

Me... I say give me the facts.....just the facts.......not conclusions drawn by a biased and preconcieved mind.

Didnt the Brisbane City Council throw all their trucks on it a while back ? or was that hybrid diesels ??

Wonder how thats going ?

They fitted d gas kits to use lpg as a catalylst to improve combustion conversion. Bio diesel is good in non direct injection diesel but dont run in direct injections as the micro filters in the intake to the high pressure pumps and the clearences in the pressure regulator valves is 3 microns and will block very quickly running bio fuels. i used to run bio in my surf but now the colorado would be too expensive to fix to save money on fuel.

2nd you dont get the same milage out of biodisel as normal and if you dont blend with normal diesel in winter you can have hard start problem.

If you have a vehicle under a new car warrenty then warranty void if you have a problem with the vehicle.

you do loose some 5 to 10% of economy????? running DB100 but at less that 35 cents per lt I will wear that loss

the unit value of energy is less in a lt of Bio as opposed to diesel but the cetane level is higher as is the oxygen level so it runs and fires better than diesel

you are right about the o2 and cetane levels but that is not always a good thing, there are 12 different reagions in australia for fuel mix each having upto 6 different blends that change seasonally due to climate hence running pure bio is not good.

Yeh but we don't all live in the frozen south

If you are making BIO in a cold climate, you will probaly be a bit more selective in the source oil you use.

Like it is unlikley you would try making BIO out of animal fat in a Tasmanian winter......even with a free flowing vegitable oil, you will be heating quite a bit to get a sucessfull processing outcome.

But in Wepa in summer you may not be heating at all even with animal fat.

Anybody making BIO will know all this.....it is covered in the books and web sites quite early in the piece.

Remember BIO is best when it is carefully hand made, rather than sold as a universal comodity.....and anybody with an alternative bone in their body will think that is a good thing.

Wonder who is distributing this diesel??
