Was a 6 page article on biodiesel in Feb/March Mother Earth News (USA Mag)
You should have no problem running up to 60% Veg oil with 40% Diesel even down in chilly Canberra. Just make sure firstly that your veg oil is liquid at normal outside air temperature. In other words it should not be the kind with a caking agent in it to make it a solid for ease of transport and storage. Second when you want to test a mixture make it up up in a small bottle say 60% Veg oil and 40% diesel then put it into the fridge untill it reaches the minimum overnight temperature which your fuel tank may experience. Then test for consistency. Keep trying different mixtures till you are happy with cost saving V confidence that it will run through your fuel filter. If you are concerned just put a Jerry of diesel in the back to dilute your tank mix, and a tin of ether or Aerostart in the glove box. If the engine is labouring and loosing top speed thin down the mix or if it stops and won't restart thin down the mix and use the Aerostart to run the engine at idle till it draws the thinned mix from the tank. Believe me it works I ran on beef tallow for a while and made a few mistakes.
Thanks for the replies, everyone.
I was reasonably confident I could get away with 30% VO in the Diesel. Of course, I'd only be using new, clean VO not used oil. My engine uses CR injection, so I'm most concerned about viscosity. Older (mechanical) injection systems will tolerate a wider fuel viscosity range than CR. I figured to start out at 10% and increase the ratio incrementally.
My tank holds 60L. To fill it with Diesel @ $1.35/L, it will cost $81.00. VO can be obtained in bulk for $1.00/L (maybe cheaper if I took a really good look), so, at 50% VO, 30L would cost $30.00 plus 30L Diesel $40.50, a full tank would cost $70.50. That's a saving of $11.50
Commercial Biodiesel Available
I was using the WA govt's Fuelwatch website https://www.fuelwatch.wa.gov.au/ and noticed that they have flagged the availability of Biodiesel/diesel belends at some Gull Service stations here in WA. At the moment the price is a couple of cents cheaper than the straight diesel price for a 20% biodiesel/80% diesel blend, but even at the same price at least you are showing demand for a renewable fuel. I guess the more demand that is shown the sooner the introduction will become more widespread (to the limit of current production but it might encourage greater production too) but there is also the benefit of reducing fossil fuel consumption now and associated greenhouse/toxic gas emissions that go with it. No doubt the price will soon match diesel as the profit motive drives the manufacturers and retailers, but at least there is an ethical and environmental benefit.
For your information. By the way, I am still running on my used veggie oil/diesel mix so far without snags. Cheers,
I ran a lister / petter generator on 90 % veggie oil (coconut) / 10 % diesel for over 1000 hours with better engine and fuel system wear than a similar engine using 100 % diesel. - This was confirmed by Lister / Petter in the UK.
I preheated the oil, prefiltered it, and then simply upgraded the on-board filter system. (They say that toilet rolls are very good!).
I flushed the fuel system through before switching the engine off by using a simple valve and running for 15 mins on pure diesel and always started on 100 % diesel.
wow all you people are real smart !!! that was some real interesting stuff ! but why didnt someone reply to the bloke with the suzuki carry? i just bought a dodge truck 8 tonner big petrol V8 mother chews an enomous amount of fuel to carry my excavator round is there a petrol alternative ?
"is there a petrol alternative ?"
Woodgas is my preferred alternative for petrol motors

The following info on butanol was posted to the energy resources list this morning
1.. Higher energy content than ethanol.
2.. Not as corrosive as ethanol.
3.. Uses the same air/fuel ratio as gasoline. Ethanol does not.
4.. Can be shipped through existing fuel pipelines where ethanol must be transported via rail, barge or truck.
5.. Can replace gasoline any percentage up to 100%. Ethanol can only be used up to 85%.
6.. Gives better mileage than ethanol.
(https://www.businessweek.com/autos/conte ... tm?chan=au\
7.. Safer to handle than ethanol.
Most commercial Butanol is produced petrochemically. Butanol can also be
produced by fermentation of biomass with the bacterium Clostridium
acetobutylicum (https://en.wikipedia.org/wiki/Clostridium_acetobutylicum ), which produces a low yield. David Ramey of Ohio and his company, Environmental Energy, Inc. have developed a two stage fermentation process.
In this process, biomass feedstock is first fed to the bacteria Clostridium
tyrobutyricum, where a large percentage is converted into butyric acid and hydrogen. In the second process, the butyric acid is fed to the bacteria Clostridium acetobutylicum, where it is converted into butanol. Ramey has claimed a 42% butanol yield from this process.
a.. Environmental Energy Inc (https://www.butanol.com/ ) - has developed and patented a process which makes fermentation derived butanol more economically viable and competitive with current petrochemical processes and the production of ethanol. This economic improvement was developed under a federal DOE/STTR grant from the Department of Energy through the Small Business program. Using corn feedstock the production cost is estimated at $1.20 per gallon.
a.. ChemLac Inc. (https://www.butanol.com/page2.html ) (subsidiary of EEI) dramatically improves cost efficiencies to produce biobutanol by eliminating the corn feedstock accounting for 40% of the production cost of corn based alcohol fuels. By utilizing whey lactose, a by-product of cheese manufacturing as the process feedstock, ChemLac Inc. eliminates the raw input material cost, reducing the production cost to $0.85 per gallon.
1.. . 64,000 Methanol
2.. . 84,000 Ethanol
3.. 110,000 Butanol
4.. 115,000 Gasoline
5.. 120,000 Biodiesel
6.. 130,000 Petrodiesel
a.. Butanol Replaces Gasoline...gallon per gallon
(https://blog.360.yahoo.com/blog-e.G_2Pk1 ... Zy5E-?cq=1 ) - No Gas, no engine modifications, no pollution. David Ramey drove an unmodified '92 Buick in a 10,000 mile coast to coast Demonstration Run using Butanol, a fuel alcohol, instead of gasoline. He proved that there is an alcohol made from corn that replaces gasoline right now. The '92 Buick Park Avenue got 24 miles per gallon with no modifications. EPA Test results in 10 states showed that Butanol reduced Hydrocarbons emissions by 95%, Carbon Monoxide to 0.0%, and Oxides of Nitrogen by 37%. Ramey says "With the rising cost of gas, the public wants something
today that will stabilize the price of fuel and replace gasoline in their cars.
Folks across the nation were absolutely amazed by how simple it was to change the fuel to Butanol!"
1.. Butanol as a biofuel (https://www.lightparty.com/Energy/Butanol.html) -
Butanol solves the safety problems associated with the infrastructure of the hydrogen supply. Reformed butanol has four more hydrogen atoms than ethanol, resulting in a higher energy output and is used as a fuel cell fuel.
2.. Other Biofuels (https://running_on_alcohol.tripod.com/id24.html ) - Butanol is another amazing alternative fuel, because it can be made from things like rice straw and old newspapers. It has as much energy as gasoline (BTU'S/gal), it burns with the same air/fuel ratio, and it will even mix with gasoline which means that you don't have to drain your tank first in order to use it. You don't even have to re-tune or adjust your engine. The best part is that it can even be made from lawn clippings and leaves.
3.. Information Bridge
(https://www.osti.gov/bridge/product.bibl ... _id=843183 ) - DOE Scientific and Technical Information. It is possible to produce butanol from corn for less than $1 per gallon. Current butanol production is from petroleum costing $1.50 per gallon and wholesales for $3.80. Butanol is safer to handle than gasoline or ethanol. When substituted for gasoline it gives better mileage and produces less pollution.
4.. Wisconsin Technology Network
(https://wistechnology.com/article.php?id=2503) - Butanol production can be enhanced via the utilization of a micro-organism known as C. beijerinckii. The genome of this organism was sequenced by the Department of Energy's Joint Genome Institute. Butanol has storage advantages and can be used not only in internal combustion engines but also in diesel engines.
5.. Green Car Congress: Boosting Biomass to Butanol
(https://www.greencarcongress.com/2005/07 ... iomas.html ) - Anaerobic butanol fermentation process delivers 42% more energy than ethanol.
6.. Bio-Butanol (https://i-r-squared.blogspot.com/2006/05 ... tanol.html ) -
Article at R-Sqared. 110,000 Btu's per gallon for butanol vs. 84,000 for ethanol and 115,000 for gasoline. Butanol is six times less "evaporative" than ethanol and 13.5 times less evaporative than gasoline. Butanol can be shipped through existing fuel pipelines where ethanol must be transported via rail, barge or truck. Butanol can be used as a replacement for gasoline gallon for gallon e.g. 100%, or any other percentage.
Newby to this scene looking for Perth buddies to work on wvo project.
Have found interesting info here, thanks to those who input.
My email is [email protected] for direct contact.
Like to hear from u. Cheers
Am working my way through the list of websites you referenced.
So much reading!
paricularly like the "journey to the future" website
Have gathered a few links and photos here
https://renascent.ratbag.googlepages.com ... sproducers
These units can burn near any biomass and would be easier to keep running when all the fish and chip shop freebies are gone
I see it is your links I am following, not Jez's - but you both have contributed so much great stuff....
