Hi, sorry to jump in. Please can you expand on this it would be really useful to know exactly what you were doing. You are one of the first examples I have seen anywhere of someone having a real problem (not "I read, I heard, I think, a dealer/friend/village idiot said"). I have a load of waste veg oil settling at the moment to use for the first time, so I am really interested in the answers

So lots questions:

- What if any conversion did you do on the vehicle?
- What oil were you using (straight or waste, rapeseed, soy or what else)?
- How did you prepare the oil eg filter/ remove water)?
- Did the oil you used have additives (eg anti-foaming agents, usually E900)?
- Did you run 100% or did you add anything,if so what proportion?
- Did you run veg all the time, or did you sometimes run straight diesel?
- What did you do on fuel filters?
- What mileage did you do on the veg in total?
- What is the nature of your driving - eg lots of short runs not up up to temperature, or long motorway runs?
- What was the state of the vehicle when you started (any existing problems/ how many miles on it)?
- Was there any indication that there was a problem before it happened/ how did the problem appear?
- Can we see some photos?
- Has the acid in the oil attacked any of the surfaces in the engine?

Loads of questions I know, but any info would be much appreciated.

You're probably right, but this is reality for some people.

If you have got the time, skills and equipment then you know that the financial downside of pouring veg oil into a landy engine is pretty low. There are others (probably not on here) who are happy to go to a main stealer to get a bulb changed. Then there are those in the middle who know they are going to get bent over if they have to get work done, but can't do anything about it. If Elt is in this unfortunate situation, well done for coming on here and sharing/'fessing up.

For me - I just got 800 litres of waste veg for £130. Diesel would have cost me £800. If I get through this lot (say 4,500 miles) then I think I have any downside covered with the £670 I would have saved. I can do a lot of stuff, but I haven't opened an engine in my life, so there is a risk. For someone who has to rely on a dealer and can't get such a cheap source, then they will need to do 10-20k miles before they can feel safe.

No worries. I am going to use it, 100% WVO if I can. The first 160 litres is settling and should be ready next week. I just thought it would be worth narrowing down why this guy had a real problem.
 
Just a word of caution to any of you using biodiesel bought from the pumps. Just recently there has been a spate of PALM OIL being used for bio-diesel. If you experience problems with cold starting or loss of power this MAY be the reason. It wasn't used diliberately by the manufacturers but it was supplied to them by unscrupulous suppliers who sold it as normal vege oil.:mad::mad::mad:
 
I looked into this last year & have got a filtering station in the garage, but got no further as all the outlets, cafe's pub's chinees's etc all said that the suppliers have a deal with them to collect used oil. So after trailing around for a bit, I gave up, epecially as diesel has come down.
One of the things I found out was its far better to use a twin tank system from someone like Welcome to dieselveg.co.uk which I might still do.
 
Came across this thread by accident, I'm not really bothered one way or the other but does anybody really know the answer? Thing is this, I know Elt, I've seen what veg oil did to his engine, I also know the costs he stated are probably better than most would be able to get things done for. I always thought you had to add stuff to veg oil to make it work properly and safely and also that it was necessary to heat it up so it can flow and burn properly.

Seems to me it might be best to run diesel engines on diesel but I accept I know b all about it. So that's my 10 pennoth.
 
I run my on own Bio Diesel (real biodiesel) and know many people that run either bio or veg... the one's that run landies on veg do so through a twin tank system... according to them (I know... hear say) landy diesels don't burn the veg oil fully when the engine is cold, so some unburnt veg oil drains through the bores and contaminates the engine oil which needs changing every 3 - 4 k to be 'safe'. Once hot they are fine.

Personally I've done 12k on 100% bio, no mods, no probs mixing with Diesel and a saving of about £1600 on fuel so far.

Checkout Using Vegetable oil as a diesel fuel and don't trust what you read on the JtF site... their information is suspect.

Oh yea... Diesel engines are named after their inventor not the ****e that fuel companies chuck out... and Rudolf Diesel run his prototype on peanut oil!
