the program said certain cars could run straight on unaltered rape seed oil. The van they had running on chip oil had the oil thinned down with a
solvent but they didn't mention which one
Hopefully someone else here is more knowledgeable which wouldn't be difficult

The main problem with Veg oil is that it is viscous and can buggar up injection pumps, most older diesels (not common rail) shouldnt have too much of
a problem with running veg oil.
I know some americans mix veg oil with either petrol or ethanol (5-10% mix) to try to thin it out a little,
Another major problem is it gels at low temperatures, so a heated tank may be needed in winter
Have a read of this

I've run my 1.9 (non turbo) xsara on 50/50 oil/diesel for 1000's of miles no problem. Its a dirty knacker so not bothered what it does to
the car, but there have been no effects at all, well apart from the chip smell  It take a few more turns to start in the morning, and when its cold
i put a little less veg oil in, but other than that go for it

Just to add, it doesn';t save you that much now though, a couple of yeras ago veg oil from asda was £1.25 for 3 litres, its nor £2.98!!!! Is
veg oil related to crude oil prices

You usually mix it with methanol. You need to filter it first.

only if its 2nd hand oil, i.e. from a chippy and been used for frying. I stick it in straight from the bottle as supplied by asda

Only problem I can see when doing this is you are evading Fuel Duty.
If you register as a private fuel producer, you can make quite a lot (I think its 2500 litres) per year without a lot of hassle or tax. but you would
need to look into it in detail.
I have a mate who makes his own Biodiesel for about 60p per litre tax paid. (and properly registered with Customs & Excise)
Dont know what the costs are now. That was a year or so ago.
Worst case, is they impound and crush your vehicle for not paying the fuel tax.
Be careful and check the legal aspects first.
1. The point of a journey is not to arrive.
2. Never take life seriously. Nobody gets out alive anyway.

Methyl Esther Biodiesel is made by mixing Veg oil, with Sodium Hydroxide, and Methanol.
This separates out the lanolin which makes the oil thniier and very like diesel in viscosity.
There is no reason why straight veg oil wont work.
However, look at the outside of a chip pan and then think of your engine.
Also the injectors and pump need the thinner liquids to provide the lubrication of the pump, as the thinner liquids can get through the tight
tolerance gaps in a Diesel Injector pump.
This is why cutting it with diesel etc is an advantage.
Believe me an injector pump rebuild is Expensive. Mine was £880, and I removed and refitted it to the vehicle.
Direct from Land Rover it was £2500 new, and £1500 reconditioned.
Its not a cheap item to replace.

I think The Veg oil rules have now changed.
I believe low users don't pay duty now.

No, but the supermarkets have probably cottoned onto the demand by now.
I've seen several people lobbing sunflower oil in their tanks in the car park of my local Tesco. The looks it draws from people not in the know
are very amusing - although no one ever stops to question the people doing it

You don't need to register as a fuel producer - just crack on up to 2500 litres/year.
On the PSA XUD engines the Bosch pump is what you NEED, if its got a Lucas forget it, it will run but the pump will die - its just a matter of when
(not usually very long).
Although its largely not worth it at current prices if you're buying new oil, and even used stuff (which you've gotta go to a fair amount
of hassle to filter) is in high demand.
Customs take a dim view of certain solvents being put in your tank.
With the PSA XUD engines or IDI Merc's all your trying to do is lower the viscosity so it starts better in the cold (and is kinder on the fuel
pump).
5% unleaded has the same thining effect as using 40% normal diesel.
I ran a veg car for a few months earlier in the year when you could still get oil for ~55p/litre but it was pretty much too much hassle even then (as
it was 1 litre bottles!). If I wanted 20 litre cubees it was an hour round trip and about 75p/litre or locally about 85p/litre. This was back before
normal diesel shot right up but then as someone else said new veg is ~£1/litre.
And the Merc (with my right foot) was only doing mid-30's when I can get around 50mpg from the Bimmer as its faster and handles better....

i was thinking of knocking up some 50% oil 48% diesel and 2% unleaded, seeing how well it mixes in a jar and then testing in the van.
The van's a shed thats getting sold soon, so im not really bothered if it dies. Plus, im spending about £200 a week on fuel so could save a lot.
Just need to find somewhere for cheap new oil in bulk.

To be honest with new oil at ~£1 a litre by the time you're mixing it with diesel at £1.30 and the time it takes to buy it and mix it coupled
with the potential risk of damage its not worth it for the tiny saving.
All in IMHO of course!
