Veg oil conversion

[Snagger]

The TD is an engine highly prone to cracked heads and pistons, so check it very carefull before you buy. Its Lucas pump is not especially strong, and vegoil will damage in very short order if not heated. You would need a twin tank system to run pure diesel while the engine is cold and purging near the end of the run to prime it for the next cold start.

Welcome to the forum.

so butting in do you just pour in tank?....no processing?

just mix with you own diesal

For up to 50/50 mix - yes. Bear in mind though you will get problems in the winter as it will clog your fuel filter quicker. The better answer is to find a renault or Peugeot fuel filter which has a coolant heater built in. These are the same footprint as the standard CAV units, and can be picked up relatively cheaply.

I would try to find one of these, then add to it by fitting a flat plate heat exchanger. Then you may opt for a two tank system with the valves etc.

Even if you don't go for the twin tank conversion, it will prevent problems with the fuel pump.

I have a Disco TD5,which I bought recently and it has given me no end of problems with the injectors, it has done 75k miles and the injectors were worn. Various specialists were involved in getting it going. I needed a new lift pump, filters and injectors to sort ot out. When the pump went the mechanic found a load of sludge in the tank he said it matched a defenders tank which he was working on which had the same problems and the owner ran his on veggie oil. The injectors were tested and were worn and would not deliver enough fuel through the power range. I didnt run the car on veggie oil but signs pointed to it running on it. I would be worried about the long term problems it might cause especially on the injectors. However I am no expert

Hi guys - just to add my tuppenyworth. I have been commenting on bio - 2nd generation type - for some time. See entries here on other threads.

My TD5 defender has done 13750 on pure processed old chip oil and is very happy on it - no probs at all unless you class a few seconds on the heater plugs plus a few seconds on the throttle till running smoothly. Processing is very satisfying when the fuel has correct PH and clear - looks good enough to drink - not sure about that one but as it is just rape-seed oil should not be as dangerous as dino-diesel!!!!

That's not running on vegoil, it's using biodiesel.

It started off as veg oil - old and lumpy!

Hi all
I am new to LandRovers, having just bought (and loving already) a '94 Discovery 300TDI.
I'm very interested in saving some money at the pumps and have been looking through many threads just like this one. In relation to the Customs and Excise thing.... the official wording on their website is this

4.2.1 Exempt producers/users
If you have produced or used less than 2,500 litres of:
■any biofuel, or
■any other fuel substitute or additive
within the last 12 months, and/or expect to produce or use less than 2,500 litres in the next 12 months, you are an exempt producer and do not need to register with HMRC and account for duty. However, there are simple record-keeping requirements, which are described in paragraph 4.9.1.

The whole document (heavy reading indeed) can be found here

basically it seems to me that if you use a full tank of PURE VEG OIL (and no diesel at all) a week, then you have to register as a biodiesel producer/user
12 gallon tank = 54.48litres x 52 (weeks)= 2832 litres per year

Obviously if you are mixing it 30/70, 40/60 or whatever, as long as you dont use 2 tank fulls a week then you are classed as exempt. You still need to keep receipted records of the oil you have bought and I would presume some photographic record of your mileage over the year.

There you go folks, the legalities of it straight from the horses mouth (hmrc.gov.uk).

I'm going straight to Sainsbury's to buy 10l and dump it straight in !!

WOOHOO - no more "over a quid a bl**dy litre" fuel for me (well, maybe a little every now n then)

Welcome to the world of veg oil

I guess the only chance of the authorities knowing you are using veg oil is if you get stopped by the police and 'dip tested' by customs and excise.

Of course, you could just keep the most recent receipt for your veg oil purchase, and if challenged you could say that it is the first time you have used veg oil.

Dont see how it could be proved otherwise.

(Not that I would ever do that!)

My understanding was using pure/ veg derv mix veg oil still incurred duty. To be duty free it had to be proccessed ie made into Biodiesel.

Also read a number of threads where people get coking problems trying to run pure veg oil with doing a conversion.

I would do some more research first.

I highly recommend everyone reads the pages on Revenues & Customs website, it is pretty heavy reading but the legalities/duty info is all there.

if you "prepare" the mix at home, you are technically classed as a producer and then you have to pay duty on it all. if you are only a "periodic user" then providing you use less than 2,500litres a year, all you have to do is keep your receipts for the oil you've bought.

i have a 96 range rover with a bmw engine ( currently blown ) so if anyone knows of a decent engine !!! , can any one reccomend some one to either help me fit a twin tank veg oil system to my RR , or do the job and the best way to go about it

Just to clarify, the "preparing" means if you process WasteVegOil (WVO), by taking used oil from say a chippy or chinese first, filtering/de-acidifying or whatever and mixing with diesel at home or if you have biodiesel manufacturing facilities etc. If you're just buying StraightVegOil (SVO) and glug it in, you can use up to 2500litres a year without having to register. Well, thats how I read it on the HMRC website so i suggest everyone reads it. I'd keep my receipts though, just in case

Hi All.
I`m new here.
I am considering to buy a Defender with the Td5 engine and converting it to run on veggie oil.
Here I`d like to share with some stuff I`ve founded about converting it.

i run my 98 300tdi on 6 litres of veg to a tenner of white stuff runs great, quieter, livelier pick up and a few more miles.
