Chip fat?

Delboy

Guest
I'm making arrangements to see a van with a common rail engine, but he also has the equiment to make fuel from chip fat. But this type of engine, I believe, is not compatible, he has said he hasn't used chip fat in itl, but has he? Is there any way of checkingl

regards
 
thi site may help How to make your own fuel for you to decide , but a common rail engine is not ideal to run on veg oil due to the high pressures needed in the injection system i have a mecedes c class 2.5 diesel and is perfectly ok to use veg oil as it is direct injection , and for a while used a 50 50 mix diesel and veg oil but i did find that the performance was down and my fuel consumption dropped from upper 40 mpg local running and 50 to 60mpg motorway runs by about 10 to 15 mpg on oil not cost effective in my case . but you say you have the equipment to convert wvo so that may run out at about 50 p per litre depending on availability of old oil , intrestingly many say that common rail engines are unsutable for bio fuels any way , you will also need to change fuel filters more often and also engine oil last less time also and the rubber seals in fuel pumps are affected more with veg oil
 
Plug in a service agent's engine diagnostics box of tricks (plug lead under the dash) of and see if any fault codes come up.

Contaminated fuel often causes faults such as low pressure in the common rail, and this may show up as an intermittent fault on the diagnostics codes.

I had a poor fuel load in my Movano/Master (probably water in the diesel) last xmas and the van was almost undriveable. It cuts out at speed under any kind of load eg slight hills and you need to bump start it in the right gear, after switching off the ignition to reset.

Its mostly to do with the injector pump, if it can handle the extra viscosity of veg oil. My Citroen Relay 1.9 and my Peugeot 306 (both have the same 1.9 XUD engine) can and have run very well on veg oil. Another problem area is rubber seals, hoses etc. Some of them will rot with veg. Theres a database of cars/engines somewhere online that says what will and won`t run on veg.

I`m not sure if you can tell if an engine has ever run on veg oil but if it has run recently you can smell it easily.
 
the way i look at it if he has the equipment to make the fuel then the van more than likely has been run on it .its up to you wether you belive him or not . and has the equipment been used at all ,it can be a minefield buying a used diesel due to the worst case of the viehcle may have been run on red diesel many motoring accosiations recomend a garage chec to see if the car/van has been used on red as it is expensive and difficult to eradicat a recently run diesel system .any trace if you are checked and your motor is taken .no excuses
 
hi mandrake ,enlighten me so what differance does it make if a vehicle as in the past run red. so long as you dont run red on the road is there a problem. some vehicles hardly ever go on the road run red most of their lives . put clean diesel in the tank ,drive on. doyou know something i dont . be interested if you do. i do know if you have red in the tank but have a reciept for the duty you cant get done. using red isnt an offence its not paying the duty .
cheers alan.
 
I have read this on a forum before though I can't for the life of me remeber where, the red deisel has a red dye in it and even if you have been only running normal deisel and the othorities do their checks some parts will still have a layer of the red dye even after prolonged use with normal deisel, the nigh on impossible part will be trying to prove when the red deisel was last used.

The recomedation they gave was to replace the fuel filter and injectors once all traces of red deisel was flushed out of the fuel tank and get it done at a garage keep the recipts and get the veichle mileage noted on the recipt, thus giving you a set point in the veichles life you that you can prove there has been no red through the system since. Do this ASAP after getting the veichle.

Squibby.

It is not the red dye that shows up months after going back to running on regular diesel. The red has a chemical in it that is detectable by the inspectors dip stick.

Veg oil? I have been running my Bongo on 80% veg for the last two years and get better mileage and a much quieter and smooth running engine with much lower emissions. There is a very long and in depth thread on this subject on Bongo Fury website
 
Mariners

All the fishing boats i know the skippers put parazone in with red ,this cleans and keeps diesel bug away.:boat:
 
There are very long threads all over the place on running and producing SVO or recycled VO. Its use as a fuel has led largely to the 300% increase in price in supermarkets. In short, there is no guaranteed answer as some engines run on it and others don't like it. Similarly, as quite correctly pointed out above, fuel pumps are a significant issue, and (often especially with imported vehicles) a problem with rubber parts, particularly fuel pump seals perishing.

Ironically the original diesel engine as invented by Mr Diesel was designed to run on peanut oil, it was us who changed it to run on fossil fuels.

The danger with running high levels of veg oil is that it often requires a preheater to be fitted.
 
I think you will find that it is indirect engines that are ok to run on veg oil [ not with CAV injection pumps I hear ]

apparently veg oil damages the engine if it is not warm before it enters the cylinders , deposits on valves etc
 
im going to ask my local takeaways for old oil. been on ebay and seen different micron filters which look ideal.

also lots of people on ebay selling used oil, either cleaned and ready or pre cleaned up.

with my VW, i asked on a VW group and lots of people use it, pure, 50% or 80%. one person had rubber fail in the pump, but then over years they can go anyway (my bmw went when i was in deepest E Germany always ran on diesel.)

hopefully i can get some before the big meet, so can see what its like, i guess 50% to start off with.

i am designing a 200litre storage and triple filtration system for my camper, so i can go around Europe next year.
 
Most if not all common rails will not like either WVO or even good BD in any quantity.

If you have anything other than an old inline or a Bosch rotary pump beware.

In case you think you will pick up good quality chip oil from your local chippy think again. They know exactly what it's worth. If you are offered it for free then it's gonna be crap.

Finally if you do get lucky and get some you will require a waste contrators licence to remove it from their property.
 
And remember the taxman - you're legally allowed to produce 2500 litres per annum tax free. Averaging 30mpg running 100% veg oil (please don't!) this gives roughly 16670 miles of driving.

Lucas fuel pumps do not like it at all. Read round the forums for our make of vehicle carefully before embarking on it, and for whoever said they were going to produce their own, make sure you filter down to a minimum of 5 microns, prefrably less.

Also don't be surprised if using it for the first time that your filters clog up faster and you lose performance. Veg oil cleans all the rubbish out of the fuel lines, so expect an initial extra expense in fuel filters.

I used to do it in the days when you had to register as a fuel producer and have Health and Safety checks to do it. In the end, the availability of free oil and the price of supermarket oil meant it just was not worth while. But hey.... if you can make it work, good luck to you!:wave:

theres a place in sheffield who wants to get rid of used from their restraunt so thats not a problem.

My engine is fine, plus will change the filters soon after as recomended
 
the rule of thumb is ,if youre engine is the common rail type ,veg oil will kill it full stop. if not then you can check on the veg oil forums .but they should be ok . there are many forums on the subject that will give the full story of running on veg oil or bio fuel . my merc car runs perfectly well on it .but its is not the cdi common rail model but at between 40 to 60 mpg i cannot be bothered messing about cleaning old veg oil or making my own bio ,and new veg oil unless you buy in bulk at cash and carry is not realy cost efective in my case .

yes seen down to 1 micron filters. hold 20 litres, hence doing 2x100 litre storage units. early days yet, just getting into looking and reading up so i do it right

Yeh those were the days. Fuel producer licences and monthly returns. Oh the good old days. Not worth the both now free WVO is a thing of the past. I made 10's of thousands of litres of BD I even made the reactors for other people to make their own. Still have a few reactor vessels left.
 
mcdonalds must be doing something different because in there tv ad they recon there recycling there cooking oil and using it in there trucks which i would say are common rail unless there not bothered about the engines

yes free oil is realy a thing of the past ,some still say they get free oil but thats rare now . the majority of fast food places ,chippies kebab shops those types have to produce paperwork stating where and how they dispose of the old waste oil nowadays and how much . nothing stays free nowadays for long . we live in the uk dont foget
