Most seem to have a strong smell of thinners or some other solvent in with the fuel.
We've had samples analysed but the lab can't positively identify the culprit.
Thats interesting. If you know would you pm me the servo brands. Rig is running fine but I an 2-300km down on distance this tank already! I'm not even half way though it. I plan to search for leaks this weekend.Quote:

Please don't write biodiesel off because some dodgy people are cutting it with crap.
Keep informed through www.biofuelsforum.com and keep your eyes open for the new association we have just incorporated:
Australian Biofuel Users (ABU) http://www.biofuel.org.au
ABU is currently discussing the best options as far as suppliers of inconsistant quality biodiesel goes.
cheers,

keh? how the hell can an engine thats making less power cause more wear? if thats true I should be absolutey killing my series parts.Quote:

As for your 10c per liter savings Im making experimental batches and each litre costs me between 21 and 25 cents per litre the diesel I bought today cost me $1.29 a litre. Unless your using my wifes accounting thats about $1.04 to $1.08 back in my pocket.
particals yes, no, Maybe? (lubricity I'll get to next)Quote:

The big problem comes when the bio picks up the stuff thats already in your fuel system theres also the problem of it slipping past seals that are worn and once that happens theres the fuel leaks to deal with.
from an experiment I did last year the hydroxides and ethanol used in the production of bio are not plastics friendly.. I took some of the ethanol and soaked a fuel injector in it for a week the result was not something I want to see done to my $1550 injectors and the hydroxides made the ethanol look like something that Id happily recomend as injector cleaner.
I might be wrong here but isnt high flow diesel just the indicator that the pump has a big nozzle and a high flow rate compared to a normal pump?Quote:

all oils have a "filming" pressure which in a nut shell is how hard you have to press 2 things together to dissipate the lubricating film of oil. An aftermarket stabiliser will help sort this out...
That still leaves you with the "how good is your bio?" conundrum..
IMHO Bios a double edged sword. Perfect Bio in an electronic diesel that has all the right type of materials in the fuel system that hasnt yet been run on normal diesel should be fine and dandy as theres nothing to contaminate the bio or go wrong with the bio. Occasional use of good bio mixed with good dieso shouldnt be a problem as you'll get the protective benifits of the dieso.
good bio in a mechanically injected diesel shouldnt cause any problems after its had the chance to clean out the crud from the normal diesel and at less than $80 for a new nozzle for an injector (parts only) if your brewing your own and makeing a 50c a litre saving you only have to run 160l (make it 176l to make up for the 10% power loss) youve saved enough to have a nice bloke like me rebuild your injector over a 6 pack of beer and a BBQ. But I'll bet you get further than that out of a set of injectors.
[/QOUTE]And to top it off, to save $0.10 per litre only to use 10% more fuel to travel the same distance.[/QUOTE]Quote:

Too right, it should be posted if the pump is bio. And priced accordingly too! I've got a mate in seymoure who brews his own at a cost of 25-30 cents a lt. So some stations are still charging the dino going rate for the bio. Further to that I've put two tanks of the stuff in to sally anne and now I,ve got starting problems. I'll post when I figure out the exact drama.
Hi,
I lived in Port Lincoln SA for two years before moving up to Karratha in Jan 2006. For the two years that I lived in Port Lincoln I ran my MY2003 TD5 just about exclusively on the South Australia Farmers Federation BioDiesel. During this period I had absolutely no problem whatsoever with the Disco. They replace the parafin wax with canola oil in their Diesel I was told.
The TD5 ran smoother, had more power, no exhaust smoke and pulled out 2.5 tonne van better. When we moved from Lincoln to Karratha we hit Mount Magnet and lost at least 50% of power - the cause being the guts of the front muffler had collapsed restricting exhaust flow and hence turbo boost.
Landrover could not find the power problem whilst they waited for a replacement piece of pipe including muffler from LRA (it was under warranty at the time). Wheter or not the SAF BioDeisel had caused this I have no idea but the Landy seemed happy for the two years that I ran it through the system.
SAF BioDeisel seems ok but others who knows.... Hope this added some value.
