anyone running a tdi on Modified Waste Vegetable Oil, Bio-diesel(RME), or Straight Vegetable Oil?
 
As the pump and injectors rely on fuel for lubrication I suggest you check the lubricity level of any 'alternative' fuel is similar to normal diesel. For reference the British Standard for diesel is EN 590.
 
There are several people I know who run their A2´s on Bio-Diesel (RME)... without any ill effects so far.

Bye, Frido.

I have been running on MWVO for 1000 miles. One of the problems can be the increased viscosity putting loading on the pump especially during cold spells. I am mixing 25% diesel now we are into the winter.
The benefits are cheaper fuel, 70p per litre. If you make it yourself from waste oil and pay the 25p per litre duty that is all it costs!(on diesel the government get 45 per litre!)
It also helps halt global warming, lowers pollution and stops the oil going down the drains and into landfill causing blockages and methane into the atmosphere. Obviously owners with cars under warranty may have issues. The manual says you can run RME and that running any other bio fuel may end up with filter blockage.
 
Vegetable oil has a higher viscosity than diesel. This might not be a problem in the warmer months, but in the winter it is difficult for the pump to handle.

German and Japanese diesel engines seem to be fitted with pumps that are more able to handle the higher viscosity of vegetable oil.

You could add 2% or 3% of solvent to the vegetable oil. Check it doesn't separate out from the solvent by leaving it standing for a week or so. Or you could try a 50:50 mix of vegetable oil and diesel. Then reduce this to a 25:75 mix if successful. I heard of a German taxi driver who runs his Mercedes car on neat vegetable oil.
 
Hi thanks, the MWVO has a percentage of white spirit and has been well settled and filtered to 5 microns. We are slowly working out the correct organic solvents, igniters and spreaders to ensure the mix will work in any car without the co-solvent diesel mix in the winter.
Yes, neat vegetable oil usually needs fuel heaters (heat exchangers off the engine coolant)to run well but the merc engine is brilliant. In Germany there is no tax at all on vegetable oil so it makes even more sense. It is the UK that is lagging behind. Anyone in manchester want to try some? I sell for 70p tax paid with invoice.
 
70p that is only 4p less than regular diesel?
We are talking stellar mileage to see much benefit, are we not?
Run it on RED!

Your mind is best used like a parachute - OPEN
The UK does not have bad weather - we have the wrong clothes
 
Still a saving, if you want to get it really cheap, collect the oil, make it yourself and it will only cost you the duty of 25.8 pence if you do it legally. As we lobby the government more we may get them to take off the tax altogether.
The biggest saving is the planet and the environment. Estimates by 2050 of 7 metres rise in sea level mean that 150,000,000 people worldwide will be refugees.
The fossil fuel is what causes the problems. R[37][17]enewable energy does not.
 
Would love to be able to use a bike, no more insurance, no more vandalism, no more sat in traffic jams, no more washing the car, however getting to liverpool or sheffield to earn a living means transport. Bikes are an option only for people who don't need to transport things or live close to their work. Apart from the arguable use of raw materials to make the car, fossil fuels have been the most damaging area, bio-fuels are the way forward. It is not just travel, the heavier fats that are not suitable for cars can be used in generating electricity. Someone is already setting up 4 megawatts of plant! There are also bacteria that can produce oil as a waste product! there are so many ways forward that are ecologically sound. Fossil fuels will only get more expensive and run out in the long run, we will have to use the alternatives eventually so why not now?
 
Whilst on holiday I met 2 cyclists who cycled to work and back every day from Abergavenny to Bristol. Brave, brave souls,and disgustingly fit. I used to cycle 20 miles to,and 20 miles back, to work in central London. Knackered for the first 2 weeks, then fiercely competitive after that, I just had to beat every other cyclist on the road, unfortunately they had the same idea.

How far would an A2 go on the same amount of fuel as a jumbo jet to say, New York? Better still how far would one A2 go using the sum total of all transatlantic flights in any 24 hour period?
Living under the Heathrow stack and the Stanstead approach I feel that fossil fuels are being squandered up there. Why not row to New York? No I never knew anyone who did that!
 
Hi The point with the fossil fuels is not the squandering, we shouldn't be using them at all if we can help it. Global warming will be very, very serious for our children and grandchildren. Initially fossil fuels were plentyful and easy to come by, once the petrochemical industry was geared up it looked in ever more remote environments for the raw material. We have rather missed the point. Nature stores energy very quickly in the form of oils, sugars, starches, fats and so on. This means the source can renew quickly. Why not run planes on bio-fuel?
I agree with Schumacher (the scientist not the driver!!) small is beautiful, local employment and low energy is best but we also have to consider the global markets and the freedom of an individual.
If an artist wants to sell her work in New York it isn't practical to row. But bio-fuel to New York wouldn't hurt anyone, except the plants who died of course ;)
 
Go check out the Diamond Aircraft website - they are using 2 modified diesel engines from a Merc A class - to fly 4 adults plus kit at over 200mph using less than half the fuel of traditional light twin engined aircraft!

Also, i sent an article about the use of bio fuel in the 1.2TDI A2 to Stuart awhile back - it was published in Flight International magazine.

If you want to reduce emissions get Audi UK to import the 1.2 TDI - It had Euro 4 three years before the new range and pumps out 81gms/km of CO2 - that means I pay just £75 road tax per year as well as enjoy 300 plus miles for £14 of fuel LHD never made more sense!
