I have dabbled with making bio diesel but the tractor smelt like a chip shop.

Would follow your tractor to the ends of the earth Mash.

You would think, but all it actually does is make you feel hungry all the time.

Back in the day, 7-8 years ago? when veggie oil was so much cheaper than DERV fuel, I had many a slip, mistaking the chip pan for the fuel tank filler.
Those days seem to have come around again....
Will my later model turbo charged car engine be able to eat the same as it's predecessors ?
Let's see.

Robert.

It's not the engine thats the problem it's the injection pump, new high pressure pumps cant process the veg oil as it's a thicker viscosity so no don't try it in a newish vehicle. My rule of thumb is around 2003 the tech started to change to high pressure, so be careful.

Bang on. Don't try it.

I blew 2 fuel pumps and numberous filter. There veg oil makes ANY moisture into mayonnaise and bins the filter real quick.

Don't!

A little petrol in the mix might help things, me thinks?
When Alfred Diesel designed the engine, he hadn't settled upon a fuel, and was considering crushed coal...
Might need to shake the car a few times in the mornings to mix things up?

Robert.

I used paraffin - but yeah.

The trouble is they have pissed about with Alfred original design...............Not sure he invented the ECU

I have a late 90's Mazda van and it runs a lot better with veg in the summer, smooth as anything and bout 80p litre from Farmfoods . In the winter I mix 60/40 with deisel and rarely have a problem. The Maker was bang on the money though. Modern deisels, especially common rail engines it's a no no. Unfortunately my dear Mazda is gradually rotting to bits and I'll soon have to bin it for a newer van. I'll miss it

I've a similar what to do problem. My tails i recycle through the wash. I kept the heads and foreshots and collected them in bottles. I did NOT seperate the foreshots. I have a couple of stoves, a Trangia and a small homemade one which i use when camping/walking etc... so my intention was to use the heads/foreshots for this. Works great, no probs there. I also use some for cleaning, works great too. But i don't really use a lot doing any of this so now i will re distill my heads/foreshots mix. Given the amount of collected foreshots how should i go about working out what to discard when i re distill , am i looking at ABV ?

I wouldnt waste your time, you will get sod all back for the effort used.
It seems a waste to chuck it but add up the cost in running the still and time to get such a little return. I base this on my still as it runs well, maybe you will have more to recycle.
I now seperate strong smelling heads and tails from feint smelling and only recycle the feints, I don't run the feints seperately just chuck them in with a vodka run.

The old deisels will run on lots of fuels, check your pump as some are more picky but a low pressure Bosch will pump most things with out complaining.
Think about used thin oils, oil isnt always used for burning, it has other uses.

One of the classic small scale whisky methods is that the boiler charge for the spirit run is blended.
60% Low Wines : 40% Feints.

This uses up a bit of the feints. If you keep running that blend, then over time the volume of feints produced tends to stabilize.

You can try doing a spirit run just with feints diluted to 30%. I never bothered because I used to run my accumulated feints through a 2" packed column. That was to produce a near neutral base spirit that was used for other infused products.

The original Porsche engine was ran on peanut oil - there was also one trial that ran for a few years on perfume.
When I was looking at conversions a few years ago there were a couple of main options.

Straight Veg Oil (SVO) that used a heater in the fuel tank to reduce the viscosity, and blending SVO with a small quantity of diesel to again reduce the viscosity.

Interesting stuff. What really offended me was that with the SVO option you were supposed to notify the men in suits of the quantity of veg oil used and they then gave you a tax bill to make it the same price as the diesel. Failure to do so was classed as tax evasion.
