A lot of work but can be done, there are few people that do make there own Biodiesel.. They head to there Fish and chip shop and get the used oils

Im thinking on older style diesels yes, this is fine, but not the higher tech ones we have today.
You try it and let me know , Nah Not for me,
They tell me you can smell the buses running BIO Diesel, but whats the point ,
you have to build a seperate plant to refine the oil making it more expensive than "NORMAL" diesel.
To me a bit like buying bottled water,,,,,,,,,,,,,WHY
I have heard u can walk on water but have never been brave enough to ask any one if I can
Its all for the enviroment i know but i dont want to smell like my local f/chip shop
a lot of work for very little gain but each to there own
good luck with it
Workmate ran his 80 series on bio for a while. To cut to the chase, car is off the road now with a well and truly cooked engine. It began with gaskets leaking everywhere, then gradually car overheating and now it's game over. Hes not sure what happened exactly, but for whatever reason the car ran way too hot on bio and eventually just called it quits. Price was literally a couple of cents under normal diesel, so I could never understand why he done it.
The bastard made us all hungry when it was home time, and he was one of the first to leave. The fish and chips smell behind him was overwhelming. In the later stages of his engine demise, there was that much smoke behind him, the EPA people would have had a field day.
Biodiesel is one way, but it is also possible to run an old school diesel on straight used cooking oil. We met a couple wit a pair of young kids at Yulara, they had just come across the great central road in an old yellow & purple Landcruiser (47 series I think) running on only used cooking oil. At Yulara they had been to the restaraunt there & secured more supplies of used cooking oil & were spending their evening filtering it ready to put into their tank. I'm not sure what their set up was, but I do recall them telling me that some folk who run their vehicles this way have to be very choosy about what sort of used cooking oil they use, but they didn't because they had some sort of 'pre-heating' arrangement, allowing them to use the type of oil that solidifies. It was a very labour intensive way to travel, but as they explained, better than just sitting at home.
Another couple running their 4wd on straight used cooking oil

Here in the UK diesel price is nearly twice the price of home brew Bio . So guess what I run lol
As said old school pre common rail generally will run fine on SVO straight veg oil. In colder climes like here :/ it can get a bit gloopy so a few litres of petrol fixes that ;)
Does smell a bit like a chip shop but hey I'm not paying bloody duty ha ha ;-)
Emissions are virtually none too .
You'll need to be careful if your old truck has rubber pipes though as veggie can eventually rot it. This can be a problem if the pump has rubber O rings etc. Most these days are some sort of synthetic rubber so "should" good to go.
My Trol 4.2 has been running on it since I had it 3 years back , all good and "cheap as chips"
the older naturally aspirated diesels can handle it, not CRD or turbo versions, the ones I know use it straight
When I was in the uk, I had a Mitsubishi delica and I ran it on straight veg oil for around 3 years as it was half the price of diesel. I fitted electric and coolant heaters to make it thinner. The delica had a rotary injector pump, reportedly not as robust as an inline pump like the mq has, however I had no issues, even in winter. I believe the older precombustion chamber diesels are ok, but direct injection are not.

Ok, here's a bit I have gleaned from Mypatrol4x4 forum. There is an informative thread on veg oil there.
Two types of diesel alternative :
Biodiesel : more of a brewing process and vehicle needs no modifications to run. Making your own in the backyard may be illegal. You need to be more of a chemist than a cheapskate to do this one.
Waste oil - divided into two categories: waste vegetable oil (wvo) and waste motor oil (wmo)
Both can be collected for free (byo containers). In some places there is a bit of competition. Make sure the oil is vegetable oil. If it's WMO you are using, make sure you trust the mechanic, and it's just oil. I know myself it is easy to use the engine oil change pan for so many messy tasks.
Both WVO and wmo are subject to a thorough filtering and settling process. One of these is the 'woolies bag filter' Apparently it is a good size (microns) for one of the filtering stages.
Depending on your climate most vehicles will need a fuel heater as mentioned in the post above. This heats up the fats so they will be able to be put through the fuel system.
As well as some storage/filtering tanks you will need a pump to move the oil around between tanks for filtering
A reduction in power and economy is to be expected. It has less octane (the diesel equivalent?) or something. Some have used 10% petrol to cut it and bring back the octane (apparently frowned upon environmentally) but it's free, so no biggie about using more. The most you can use it is 90/10 wvo/diesel.
Long term worries about using it include the injector pump gumming up. Water injection is apparently the solution to this.
Here ends my basic knowledge.
very interesting thread!
are you aware of any legislation on home made biodiesels in Australia?
valuable links and info, thanks Cuppa!
Back in 04 i looked into the cost of make bio. dollar for dollar, i came to around 60-65 cents a liter. problem with bio is you do have wastage so that can increase costs for dumping, but at that stage it is still quiet cheap.
The process is fairly easy to work out, but its the chemistry required to make bio viable. To make it have a combustion rate equivalent to petro diesel.
If you can use a still at home, you can make bio, haha. plenty info out there. Just have to be keen to try.
Run my TD42 on up to 80% rapeseed oil. Sometimes a splash of petrol when it's cold or just more diesel. I find the sweet spot for it is about 60-70% svo to diesel. Runs lumpy for about 5 seconds on cold startup in winter otherwise I can't tell any difference in performance. No fuel heaters and it has an inline pump. Saves me about 60 quid a month on fuel. Not to be sniffed at if you excuse the pun.
