used veg. oil as a fuel

yes but you are suppose to notify revenue and pay tax on the vegitable oil lol

Payable after you reach 1000l in theory and Im not aware of anyone that has done this. Revenue were contacted and couldnt advise either. But seriously, who cares? If you were dipped, they are only looking for a coloured diesel fuel. Mix the diesel with Veg Oil and it likely doesnt really even look that different than regular fuel. Definitely not green or red.

The UK addressed this "issue" by simply allowing home users to make/use 2500litre of fuel a year and most recently relaxed the legislation further by not even requiring receipts or notification anymore, its a totally open system.

The best fuel to Cut the Veg Oil with is Kerosene (28sec Home Heating Oil) as its naturally less viscous than Diesel and offers less lubrication, both addressed by Veg Oil (which is in its natural form too viscous for your era Diesel engine). Using home heating Kerosene as road fuel though is specifically illegal however, unlike running on pure Veg Oil which is legally more grey.

All that said, the legal aspect of all this is so so boring. The technical aspect is much more suited to a motoring forum....

I was looking into this for a long time and came across many interesting tidbits like:
- Common knowedge is that only very old diesels can use SVO (straight, new Veg Oil) however I found reports from TDI (PD Diesel) and JTD (Alfa/Fiat Common Rail) owners tried it with no issues till they got to 80% mixes (20% Diesel).
- Apparently properly filtered (no water and 1micro filtration) WVO (waste, used Oil) actually performs better than SVO
- Those that had issues generally solved them by just replacing the fuel filter and lowering the % mix
- Rapeseed/Canola oil is meant to be much easier to get good results on as its less viscous than the other Veg Oil types

So where can I get Veg Oil cheaply? Its 1.14 in Lidl per litre... thats not even close to cheap enough IMO.

seriously? Don't suppose you know how much and if it 's worth it?

And if it was already USED veg. oil, then surely the tax would have been paid on it when it was paid for the first time?

But previous tax was paid on the basis it was to be used as a cooking oil, but you're using it as a fuel so that means you are liable for fuel excise. That's the theory anyway.

I have tried in FIAT Jtd engine
Won't work at all
Even in summer the engine is not starting when cold
It is too viscous and not lubricating the expensive high pressure pump

What engine, year and % mix?

Well researched there Matt...:cool:
No where is my local Spar shop...
I wonder can i reverse my trailer to there door...:D

I've been think about this for ages and once the cold weather is gone, i'll be starting to experiment with my 1998 Freelander. Its got 180k miles on the clock, so if it goes tits-up i wont mind too much.

The 98 Freelander is a Di, which does not make it ideal, but it has a Bosch Fuel pump so that is a help. I wont be putting in pre-heater or twin tanks etc, it will be the standard freelander engine.

I've done some research, but much more is needed, My plan so far is;
The used oil will have to be heated first to remove any water, then cooled and filtered.
The oil will be filtered at 25 microns before heating just to remove large crap. Once cooled it will be allowed to drip filter through a 5 micron filter and then possibly a 1or2 filter.
Before i put any oil in, i'll change the fuel and oil filters, both will have to be checked regularly and i'll have to change the engine oil every 3k or so.
At first i'll run a tank or two at 20% WVO 80% Diesel. Then raise the levels to 50%/50% if no problems.
There are a number of additives that can be used and some even use 10% petrol to keep the viscosity of the oil. I'll probably have to mess around to get the right balance, but it looks promising. Many talk about 100% WVO, but i'll be starting at 20% and just hope for the best.

I can get as much used oil as i like from work and i dont do many miles per year, i'm really just doing it to see how easily it can be done.

80% veg 20% diesel Summer 22C

The chippers get oil in 25L drums I believe. No way are they paying anything like 99c/L either. Anyway, best option IMO is the small package plant which uses old oil from chippers. It filters, heats, mixes with correct additive to get the right lubrication & viscosity characteristics & works away by itself in the shed producing your fuel.
Car mechanics magazine did a good piece on this. I think the plants were maybe 2,000 euro or so. Oil costs would be tiny though if you were to pick up used oil. I think in uk it was working out around 30p/L ready for tank including additives etc

You get cheap SVO from your local farmer that produces it. I was driving my previous car on fuel I was buying from the farmer and I was mixing it with Diesel fuel or (with smaller proportions) with petrol or white spirit. My car could do on 70-80% SVO without any conversion, but I would do it only during warmer months. In the winter the proportions should be more towards less viscous fuels.

I think thats the whole case about taxing a fuel, ONLY taxed fuel should be used while driving on public roads...

That is one of the reasons I was buying SVO from a farmer.

MarkoC wrote: »

Is it taxed to use on public roads ?

Yes, it is.

MarkoC wrote: »

Can you explain please, how much you paid for it and who paid these taxes ?

Cheers

I don't remember exactly how much it was at the time (2007-2008), but something around 80-90 cents per litre.
I paid the full price including taxes to the supplier, same way as you pay for your fuel in a filling station.

You get a receipt with the tax breakdown :rolleyes:.

By any chance you tell us more about that supplier ?

Cheers
