I was looking at a thread in UK.legal about using veggie oil in diesels and paying tax on the stuff and wondered if the posters on here had any comments on it.
I don't remember any announcement on the news about a new law and the government site:

seems to be about production quotas rather than the use of cooking oil by private
I believe that tax is no longer payable when produced for personnal use,there is a limit but not sure what that may be.There was a news item in the southwest just the other week about buying the kit for £700.00

Not a lot of help. Seems they don't want to let us all in on the secret.
The BBC article looks like its kosher. I was in an Asian grocers today and the cheapest oil they sell is the same price as diesel.
summary, small producers of biofuels for rorad use, producing less than 2500 litres/year, only need to keep production records, they do not need to register with HMRC.
For the individual running their diesel vehicle on new vegetable oil, the act of pouring it into you tank is considered "production".
I wanted to verify this, so called the HMRC help line and had the above position confirmed to me.
Asda were selling veg oil at 1.69 for 3 litres a week or so back when I looked. Tesco were charging about the same. That's quite a saving over the cost of diesel.
Tesco and Asda prices have both gone up in the last week or so. Asda now £1.98, Tesco about the same iirc. The Range Rover (300tdi) was very slow to start yesterday and today with about 40% veggie oil - it's always been almost instant on derv, without using heater plugs, and it's smoking much worse than usual.
Then I read the first post in this thread:

seemed to me to be written by someone who knows his diesel engines. I think I'll stick to straight derv, with perhaps a couple of bottles of oil when I know I'm giving it a long hard run.
You were chucking vegetable oil straight into the tank of a direct injection engine and starting on it???
Did it have a Bosch injection pump?
Regardless of ring gumming problems, if the engine has a Lucas pump - received wisdom is that the life of the pump will be severely shortened, especially if cold started on veg.
A diesel that has decided to burn it's lubricating oil is not easy to shut down. Any of the normal fuel control systems are out of the loop. You either have to starve it of air or try and stall it.
With the first, do you want to be near an engine designed to run at 4,000 rpm max when it's climbing towards 10,000... Whilst trying to stuff something fairly solid and sealing well into the air intake, if you have something suitable and if you can access the intake.
The second you stand a chance but if the brakes, gearbox or more likely the clutch give up...
No you don't. An engine that is running on its own oil is toast anyway, so you just put it in neutral or declutch and let it destroy itself. No danger to life.
You'd have to be fairly stupid to attempt that. Just walk away. Problem solved.
Why would the clutch give up? It's not driving anything if you've got your foot on it, or if it's in neutral. And why would the brakes give up bringing a vehicle in neutral to a halt? Or the gearbox?
You do know about the failure mode of diesels when they're running on the oil in the engine, don't you? You need to stop the engine, which means stalling the thing. Clutch in or neutral = engine dies terminally.
That depends on how it fails or are you saying that an engine running on it's own oil will *never* have a failure mode involving bits of high velocity metal?
Look at what I wrote "try and stall it", to avoid the high velocity metal scenario.
Not necessarily true. A friend of mine over-filled his Montego (Perkins DI TD unit), and that ran on its lubricating oil, sucked down the valve stems.
He just pulled onto the hard shoulder, and jammed the brakes on, and it stalled.
"Repair" was to crack open the injectors, turn it over until the oil was squirted out, and then re-tighten the injectors. He forgot this last bit to start off!
