cooking oil!!

[Antoin]

thanks for all the info shal hopefully be smelling like a chippy for the weekend.
anto 306 i may be in contact with you in the future to find out more about the mods you made to run your 306 on the veg oil. may convert mine if all goes well with the vento

All i did was swap from a lucas pump to a bosch pump, nothing more than that 306-d-turbo...
Lucas pump would have sh!t itself eventually if you run it on veggy oil.

You can make heaters etc for the oil to make it easier to start but when i need that il be switching back to diesel.

cheers
just had a look at the vento its got a bosch pump. so its all go geting some used oil from work tonite so i will report back tomorrow with the results

doesnt the acid in the cooking oil not burn or eat away at seals??

You cant just bung in some used cooking oil, aside from the fact you will have chips in it, it must also be filtered so if you got 50litres of used oil once its filtered through very, very fine mesh only 25litres approx is useable.....

Try it on oil out of tescos or soemwhere first.....

After a couple of tanks change the fuel filter as well as it acts a s a good detergent and cleans the lines so a lot of crap will get to the filter.

No, its the residual in poorly made biodiesel that does this.

Ive been running on veg for ages - it is a better idea to preheat

I preheat the veg oil tank with a submersible heating element and also preheat the fuel before entry to the injector pump. I use a vow2d+ heater for the latter.

get one of them off ebay or from vow2.co.uk

If you run twin tank like me you will also need a pollak selector valve. I use a tiger loop as well (Like on home heating oil systems) to keep air out.

I also have a lift pump from the veg tank to a small res at the front which is then preheated - this is how I got around the problem of having a lucas pump. Veg oil is VERY thick compared to diesel and I wouldnt say it was a good idea to do a high mix on anything without a lift pump or a preheated tank or you will soon shaft the lift pump in your injector pump.

I did shaft 2 pumps experimenting to get it right, but they were only £30 from a scrappers.

Mark ive heard no matter whether the oil is heated or not that a lucas pump will just eventually seize altogether, no warning signs nothing just one day itl let go.
Something to do with how the components of a lucas pump are lubricated as opposed to the bosch pump.
Correct me if im wrong.
Its something im interested in.

 

[Mark_C]

That is right, but it will last longer if you do as above, and warm up and shut down on diesel. I have 10k miles on this one so far.

I know of a few with a lot more than that - I put it down to starting on diesel, and heating twice.

You can shaft one of them in about 15 minutes though on pure!

 

[Antoin]

No problem, didnt realise you were starting on diesel and heating it twice.
Are you just going to drive it till it seizes and then stick another pump on?

Would you have saved the value of a new pump already in those 10k miles do you think?
So anything more is a "real" saving?

 

[Mark_C]

pumps cost me £30 each so I'd say yes!

Your flying then as long as the pump going doesnt take the rest of the engine with it....
What car you doing this on out of curiousity?

 

[nomis]

go a kit off the net a while back but never tried it its basicly made up of different kinds of cloth for filtering the used veg oil through. gonna start out running on probably something like a 60%diesel mix to see how it goes. good thing the car only cost £300 and parts should be cheap enough to get for it so its a good car to experiment on as if the worst dose happen its not really a mega loss

let me know how you get on. seen these kits and wouldn't mind trying one out, anything to save a bit of money, fuel prices are beyond comical

 

[Coog]

Ran my Vento for several months on cooking oil, and the escort on it too. Mixed it at about 50/50 during the summer and about 20/80 oil/diesel during the colder months.

No issues at all, apart from the smell which was absolutely rank, but then diesels usually are rotten anyway. Lidl Vegetable oil - 49p a litre or thereabouts. Don't forget to declare it to pay your fuel duty

One thing I do have to say is that it is a pain in the arse to fill the car up with it. Do it in old clothes/shoes, I used to cover my good stuff in oil then get a right rollocking off the missus.

 

[chrisni1986]

would a 1.9 straight derv clio run on this oil?? its 1995 like

 

[forde]

So you guys are saying that on old vag diesels (which i assume have bosch pumps) you need to do nothing to them at all apart from pour the oil into the tank? No tank heater? Nothing done to the fuel pump? Nothing done to the engine at all?

Why would you even bother making it into biodiesel then if you can use it as it is?

Also i dont see how the 1 litre bottles of oil in tesco would be cheaper, surely the 3 or 5 litres work out at less money per litre...

 

[Coog]

5 litres from Lidl - was the cheapest I could find.

You'd need a heater for a strong dilution but for a weak mix it should be fine in warm weather (less than 50/50) mine was grand. Only done about 8k miles before I sold the Vento, although the car ran for another 20k after that before being scrapped due to rust. Engine was 100% to the end and had 140k on it.

 

[Mark_C]

I would not do a mix of any higher than 40/60 unheated in the summer and 20/80 in the winter. For all the heater costs it is well worth it - but do use good fittings, short hoses (Or a tigerloop) or you will take air on

You can thin it down with petrol of all things.

I would recommend NOT filtering your own used oil unless you have a really, really good filter. I dont think its as good as clean SVO.

anto 306 - I'm running an AX1.5D on the stuff, and a 1.9TD Xantia
The AX was the one I wrecked a few pumps on.

 

[nomis]

i got some oil there and im filtering it now got it through the 1st 2 filter sheets grand but this 3rd 1 is a real pain in the arse its taking ******* ages so im assuming that it is very fine indeed will mix it up with so diesel later on and see what happens

 

[big cyril]

Used oil is actually very hard to get a hold of.
Has anyone got veg oil anywhere cheaper than Tesco at 56p / litre, if so where?

 

[Mark_C]

when I started out using veg oil about 13 years ago I used to buy from cash and carrys.

They too now are a ridiculous price.

 

[Tommy]

Ive got a 98 Xantia td for sale if anyone is interested, im currently running my 96 xantia on bio diesel and it runs spot on! going to try the cooking oil once this tank is done

 

[gixerboy]

I use a toyota van as a race transporter & have ran it on veg for two years now with no problems, during & the winter months i use a 60/40 Derv/Veg mix for easier starting..

These guys are very helpful..

[nomis]

results are in got the oil filtered, mixed with the derv and now in the car done about 60 miles tonite and it runs spot on

WVO (waste cooking oil) should be filtered to at least 5 microns or it will block the fuel filter, What derv/veg mix did you use?

 

[nomis]

dunt no wot its filtered to it was some kinda filter cloth that i got of the net in a kit form along with an information booklet on running a car on veg oil so i hope it was fine enough
