Thanks StonedofMoo. How much do you pay for 20l normally?

£11.50 last time I went

However just to answer the original question I get mine from Makro in 20 litre drums and just pour it straight in. You can also get it from any normal supermarket for slightly more in 3 litre bottles.

What car is it that you're run on veg oil fella?

Stonedofmoo · 4 Oct 2007 at 22:17

A 1994 306 Turbo Diesel (One in my sig)

Does running the car on Vegetable Oil have any long term effects on the engine?

Ive heard on the radio that someone said the stick a fiver in diesel and tops it up with veg oil and it works fine...Is this true?

This is what my mate does with his 1992 Pajero 2.5TD

So you just pour these drums of oil straight into the tank with no treatment?

Don't use it on anything but the oldest of old bangers on carb/s that you don't care about.

I hate these TV programs for telling you it'll work in any diesel.

A diesel on carbs? Have you been on the glue?

I did for a while but found the car started to hesitate. The trouble is veggie oil is far more 'sticky' and viscous than diesel and this can be dealt with either by heating it or making it thinner.

I went for option 2 and making it thinner. If you add a mere 10% of unleaded to your Veggie oil mix it almost halves it's viscosity. A guy who has done some testing did this graph which shows you the effect

HOWEVER once you have done that you introduce another knockon effect. The cetane (calorific) value of the mix drops because you 'watered' it down with petrol. So to bring that back up to normal amounts I add 100ml of 'Veggie Boost' (Google it, I can't post link) which is basically a very stong diesel cetane boost.

Once you have that in your tank it runs as well or better than normal diesel!

Total cost to fill up is round about £35-36 with current prices of the 3 ingrediants on a 60 litre tank and that will do me 450 miles varied driving. It would be 550 miles with motorway driving.

So to finally answer your question, in my fuel tank I put in around 55 litres of pure veggie oil, 5-6 litres of unleaded petrol (a jerry can) and 100ml of Veggie-Boost to fill the 60 litre tank. I never put in any diesel.

There is such a thing actually, not been done on a car for ages, and the ignition timing is as vuage, but:

Mechanical Single Point injection then. It may as-well be a carb as there is no electricity involved, in the injecting.

Basically, electronic injectors want proper diesel, especially the new ultra high pressure ones.

That is very impressive!

Another question, because you're not using diesel (but yet a tiny bit of unleaded) what are the emissions like? During the combustion process, are the same nasty pollutants that come from using normal diesel emitted?

Stonedofmoo · 5 Oct 2007 at 13:16

I can't test it first hand but I've read that veggie oil pollutes less than normal diesel. It's cleaner and has MUCH less sulphur than diesel which is the bit that gives wheezy people asthma. Some people consider it a carbon neutral fuel because it comes from crops.

Either way it is better for the environment than diesel and cheaper. Win, win really.

It produces a shed load less of most emissions but around 5% more nitrogen oxide.
But you are looking at a 45% reduction in C02 and dust.

Its probably not much better than normal diesel to be honest

You need machines to plow and recieve, fertiliser to grow it and power to process it. To give an idea: In some countrys they have burnt down forests to grow biofuels which are processed in coal powered factorys

Also the plastic bottles you buy them in needs energy top make aswell as transportation to the supermarkets.

It should have no sulphur in it as sulphur in fuel comes from the crude it is refined from

Stonedofmoo · 5 Oct 2007 at 15:17

Very true.

I don't run it because I believe it's a carbon neutral fuel if I'm honest. I run it because it's much less costly than diesel

If it IS better for the environment which it should be to a certain degreee, then all the better.
