OT - Running Diesel engine on veg oil.
Turbo Mini Forums

We have an diesel genertator in the workshop, 6 cylinder turbo thing, it drinks the fuel.

If I wanted to run this on old Veg oil, what would I have todo? is it simply a case of filtering it first?

Vegi and mineral oil doesnt mix terribly well.

Depending on the pump it might also fuck it as there are problems with the fuels lubricity.

BUT

A mix of diesel and veg should work well. Can't you run it on heating oil? Its heats the workshop to doesnt it

AlexF

What injector pump is it? Have a look and see if there is anything on it.

If its for a heater or you need alot of it, theres a grey area. You maybe able to burn old veggy oil legally. A friend been looking into it. Waste desposal licence. The cost of a licence might be too expensive, I shall keep you posted on his findings. :)

As AlexF said, you need to make sure it has a decent fuel pump.

A friend of mine ran a diesel 306 on it for a while but said a mix of veg oil and diesel is better than veg oil alone.

With old oil i would imagine it'll need to be filtered to remove the majority of the sediment.

the pump says nothing on it. it's and old perkins engine I think.

Sturgeo, what age was his 306, and what king of mis 50/50?

Is the 306 still alive?

People seem to get round running 100% veggy. Alot of it is where they are running pre-heaters to thin the oil. Ok on bosch pumps apparently. Other than that...go 50/50 to be safe.

Jimster, i'll try and find somemore out about the 306.

The problem with veg oil is that it congeals when it gets cold so a for use in a cold workshop a 2 parts diesel, 1 part veg oil mix would be best.

It can be done, but works better if you can pre-heat it as it viscosity goes down and is easier to pump. It doesn't seem to work well on a cold engine probably for the same reason.

A good way of heating it is to run a copper pipe with a water jacket round it-kind of a heater exchange unit. As its a generator it probably won't be water cooled, so your best mixing 50/50 as it has a similar effect as heating the oil.

Its good to run a tank of pure diesel through it every now and again to clear the fuel system through though.

A mate of mine was down at Avon with his LDV van. He runs a 50/50 mix with no problems so far

cheers for the info guys

A few years ago I read that when running a diesel car on heating oil it was best to stick some two stroke oil in as well to lubricate the injector pump. If it is true, this might be a good idea when running on veggie oil.

a friend of a friend had a van and only drove around his private property and he ran a bit of red deisel mixed with heating oil and it had a strange smell when running

the bloke at work almost ran out of fuel in a oil burning Belingo van and filled it with petrol!!! he then drove approx 60miles but it wouldnt restart. drained the tank and refilled and is still working many miles later. the driver said the filler cap had a green bit so he thought it was petrol!

There is a pump that can be used that works on veg oil. It was on discovery a while ago i think. And I think it was a bosch pump as milamber says.

a freind of mine has a citreon ax and a mitsibushi peoplecarrier type thing and runs them both of vegi. pretty sure its pure vegi. i think that because majority of diesel cars (if not all) have some sort of preheat mechanisms vegi works fine as its viscosity returns before it is injected/burnt.
i havent heard of the pump thing before this is new to me so dont have a clue on that.

but as people have been saying 50/50 would be best for the genny as there isnt any preheat on it.

There you go Jimbo

jim RUN A 50/50 MIX

go to the asda or tesco and run that

vegie oil has more! lubricity than the new diesel you get at the pumps ... trust me

50/ 50 mix is just right
100% mix in winter, it will tow a shade on start up

fire it in and do you bit for the planet
one thing is ........... you will put 12 stone on, because you will feel like a burger every 10 mins ....

i am responsible for all the plump!!!!!
people in my town
as they smell the oil & want fishs and chips or a chinki.......LMAO!

It does smell......like cooking batter! Noticed it on the M25 a couple of times.

I regularly run my sierra td on veg oil, I tend to run veg for a few weeks then go back to diesel, I always find the car starts to feel sluggish after a while on veg oil - I have read the glycirin in the veg oil cokes up in the injectors. Possibly could explain slugishness after a few weeks?

I have a big mechanical fuel pump which doesnt seem to mind, apparantly some of the modern electric pumps dont like the viscosity of veg oil.

The glycerin can be easily nuturalised with an aditive... I'll try and remember which one.

Benross, how do you know it is more lubricicating?

AlexF

Jim old chap, speaking from experience with my multi-fuel buggering about, I suggest the cheapest way to do it is to run K-85. Ie Kerosene 85% FRESH veg oil 15% (provides lubrication to your injector pump). Works fine. Used oil has to be transesterified which is messy and time consuming, new oil is a tad pricey (even considering red diesel) Kerosene/Veg oil or 70% Kerosene 23% red diesel, 7% lubricating oil will do it.

My pug 106 multi fuel donk shat itself when I tried running neat veg oil at about 2 deg C. Needless to say, if you are running straight veg oil and ot gets cold, the viscosity will go up exponentially, as will the drive load on the injector pump, which you will find isn't up to the job!

Stu

Bugger off, I'm getting there.

apperenly make sure its rapessed oil as the engines run better than blended sunflower oil.

my mates corsa runs fine on rape and thats neat rape to from tesco's.

always looking for them bigger bunches of bannanas

alex around 5 to 10 years ago diesel oil the viscosity used to be very heavy and oily

the new genaration of city diesel is like piss and has cause a load of trouble with pumps seizing

i go on the not so technical thought that my mates chainsaw to lubicate the blade he uses this and the chain doubles its life

anyway he has a picaso 2litre diesel turbo and has done over 100k on rape seed oil and thats neat!

not one bit of trouble
its only the chanselor who is loosing out
but they get more than enough anyway

Fight the power benross. LOL

Back once again like a renegade master

Some of the boys over here are running used auto trans fluid in there Ford trucks with no problems....I don't see why it would'nt work in any other diesel....Of corse we work at the dealership and have a ton of it here and it's fricking FREE.....

Just a thought...........Willieeeeeeeeeeee.............
