I hear one or two owners on here using veggie oil to run their cars on , my question is what car is suitable for this ??? Im presuming the oil is not sold commercially , so do you go round the local fish and chip shops then take it home and filter it or just chuck it straight in the tank :-\

Little bit more to it than just that

most modern diesels will run on some oil in one form or another without any modifications,i know a disco diesel will run on veg oil but the fuel filter needs changing and i think you have to turn the fuel pump up....but the problem comes in cold weather as the oil starts to thicken so you need 2 tanks and some form of heater,as for used oil i think you would need too strain it before use and you will smell like a chip shop,and i think there is a limit as too how many miles/litres that can be used set out by the tax man :y

Interesting info on that site and answered one of my questions :)
[quote]How much does a conversion cost?
An Elsbett “one tank” conversion, including the price of the kit and its installation, generally costs around £1200 [/quote]

might as well buy a petrol and pay for a gas converson :y

;D
Or an indian takeaway :D
And a couple a litres of oil in the shopping trolly for a top up :)

But petrol is going to run out soon and keeps going up :y

Modern diesel engines mostly wont run on straight veggie oil,they need biodiesel which can be made from veggie oil.
Older type diesels are often fine to run on veggie oil,particularily those which have a Bosch pump.
Cavalier (Isuzu) engines are great as are Peugeot xud,old Merc 190,s and lots of others.
The oil can be bought (usually unfiltered) commercially for around 50p per litre,or you can knock on doors of local restaurants etc. and try to get it free or cheap. Ime chip shops,kebab shops etc arent much use as the quality of the oils is very poor - full of animal fat - and takes forever to filter.
You need to have some system of filtering the oil.The simplest method is "sock filters" - which come in various grades. Typically from 100 microns down to 5 microns,so the oil can be filtered in stages.
Im fairly new to it,but many people speak about dewatering the oil.I dont know much about this yet,but the oil I currently use is very high quality and doesnt seem to need anything more than running through a filter to remove any largish particles.
In cold weather the oil can be too thick and cause difficult starting,rough running,and premaure pump failure.There are various answers to this,the simplest being to mix it with anything up to 50% diesel.
This partially negates the point of doing it imo as its relatively expensive.The best method ime is to mix 10- 15% petrol with the oil (believe it or not) which keeps the oil thin and makes the engine pretty pokey as well.

P.S The limit set by the taxman is 2500 litres per year of personal use. ;)

My brother has run his Pug 306 for years ONLY on homemade bio. It isn't free but not far off if you go about it the right way. You need a bit of space, lots of storage containers and a bit of patience - oh and a supply of oil and a "still"
Q. How does the taxman know how much you have used? What a daft rule. Anyway I guess that would be about 20k miles!

Thanks for that link albs and will have a read through it tomorrow ;) I did spot the old pugs and citroens being used in the link martian posted .
How does the tax man know how much your using ???
-
You keep a record of what oil you collect,where you got it from etc.Then in the unlikely event the taxman comes knocking,you show him. Tbh its unlikely an individual motorist is going to exceed the limit,so as long as your not selling it on for profit etc. I cant see any problems arising. My Cav does 40 mpg so 2500 litres would be (as Varche suggested) at least 20,000 miles p.a. I do around 6,000 miles p.a. in it.

I'm going to start running my Merc on veggie oil from Costco when the weather warms up. It'll be 80% oil/20% diesel and I'm sure she'll be fine. I used to do it with a Rover 218 diesel. :y

Sounds good or like albs said 10- 15% petrol with the oil ;)

well that intresting as know of five companies that run,focuses,octavias and volvo's,peugets all under a year all run on veg oil with no modifications and all run with no problems...not sure what it does to the injectors etc,come to think of it not sure what it would do too the warranty either :y
-
Iirc, you thin it out with ethnol :-\

What about meths or paraffin :-\
-
Illegal as no duty paid and its not exempt.My understanding is that modern (common rail ?) engines wont run on veggie oil. :-\
-
Common Rail Diesels which are mainly the newer engines. can`t / wont / shouldn`t run on it, as it will knacker the injector pump, my motor which is the older 5 pot Mercedes TD with the Bosch pump runs on it a treat, not special modifications required, I buy new veggie oil from a cash and carry in 20L cubees, if you intend to go round the chippies / take-aways etc you have to do a fair bit of filtering thro various micro filters etc, normally start off with something as simple as a J cloth which will filter down to 5 microns, you can get some real bad stuff tho` I have fitted a small-ish inline fuel filter in the main line, just before the main fuel filter, they can be changed very easy without the need to bleed the system.
During the summer months I run 100% veggie, in the cold winter I run about 70/30 veg and diesel, with a stand by fuel can of PETROL to add in case of exceptional cold,
you can not tell (other than that nice smell ) that its running on veggie, and it does wonders for your emissions,and your wallet,I believe that as long as you do not use in excess of 2000 litres per year, no tax chargeable.
-
I use a small inline filter before the main filter too.Even well filtered oil seems to be quite hard on the main filter and at over £15 a pop its worth trying to give them an easier life. :y
I filter my own oil and found it really messy work at first,but have now got a bit of a system/routine going which seems to work quite well considering I am very limited for space.
Im still running 100% veggie so far this winter but have a can of diesel/petrol mix to add if we get a really cold snap.
-
A mate of mine used to run a Vectra on veggie oil and he used to thin it using Jet A1 aviation fuel from the local Police helicopter no less!
They took fuel samples from the aircraft and fuel store before each sortie, a jerry can at a time, when a test tube would have been adequate. They were glad of someone to take it one it had been retained for the required period. ;D
-
AHEM,!! without saying to much,black diesel is far better than veg oil,and its usually free to collector as people want rid of it :y thats all im saying,hint hint
-
What does black derv burn like? Just seem to imagine it would make a right mess, and burn leaving horrid deposits behind caking everything in ash?
-
nope burns great and smoother with more power :y
-
Most petrol omegas run on a mix of engine oil and fuel anyway ;D ;D
-
Never heard of black derv.whats its normal application ?

It comes out your sump

And strictly speaking requires duty to be paid if used as fuel ;) ;) ;)

Cant see that being much good for the longevity of the diesel pump. :-\

Or the fuel filter.... :-\

True,although I suppose it can be filtered before going in the tank the same as veggie oil.

And it will have been regularly filtered whist running round the engine, down to 10 microns I think engine oil filters IIRC
-
I ran 3 omega 2.5 td doing around 50 k a year, would run 100% from april to october never gave a bother switched to diesel for the winter ,always had problems starting swmbo' s cavalier 1.7 td.
-
My old Cav starts first time every time,might hvae been something wrong with it - glow plugs ?
Ive thought about an Omega 2.5 diesel,but heard some reports that they dont run well on veggie oil. :-\
-
I ran mine on approx 50/50 with no problems a few years ago,
-
regarding the "black diesel".
was watching one of the "police-reality" shows the other day, and it mentioned that people add used motor oil to red/blue diesel to disguise the dye.
If you get pulled for a fuel-dip check, you can expect a *lot* of attention.
-
The best diesel's to run on oil are old Mercedes and the Peugeot/Citroen engines.
I used to have a Ssangyoung Musso 2.9d which uses as old 5 cylinder Merc engine - it ran on neat oil with no modifications at all, in cold weather I'd just mix in a little diesel. The cheapest cars for it are probably old 406's, 306's and old Mercs.
If you've got a modern diesel I think it's only really the VW group diesels that will be happy on it, but they're all very efficient anyway.

Were you ever in the Ssangyong Owners Club, name seems familiar,

:o Dont it smoke quite a bit using neat engine oil ???
Mind you it cant be no worse than following an lpg conversion stinking like a burst gas main ;D
