Bio Diesel on 1.9td

[adamr8965]

Hi new to the forum, this is my first post.

Would my 1.9td run on bio diesel? its a 99 t-reg, done 84k miles. If i did which parts would have to been changed?
Plus how long will the engines go for?

The mechanical 1.9td runs a bosch pump, you don't need to bother with bio-diesel, just chuck pure veg oil into it.

But if it's the HDI version then you'll need to use bio.

Its not the hdi its the 1.9td tractor engine

You sure just chuck veg oil in? wont it break it? Can it be used veg oil from the deep fat fryer minus the old chips? or does it have to be new oil?

So no mods at all?

[StevieboyTD]

Mine hasn't seen fuel from the pump for a long long time ;)

No mods, be prepared to change the fuel filter a couple of times as the heavier veg oil with scoop up the crap from the bottom of your tank.

Currently running cleaned used oil, but if that's hard to find i pop to cash n carry and buy 20L for just under 15 quid. Even at full price it's nearly 50p/L cheaper than diesel.

Be sure you've got good glowplugs for frosty mornings (got a few months before that is a worry again anyway)

used stuff needs filtered well to remove all contaminants and contains more fat than new oil, but adding 3% white spirit breaks down all fat and bonds it into emulsion form so it burns instead of coating the fuel system and tank. More tolerant of the cold then too - add 3ml white spirit per litre of veg oil.

A wee cheeky scheme I had, was a plastic heating oil tank mounted in the rear garden.....costs 35p to 50p (may be more now) a litre for white heating fuel (diesel) - its NOT legal to use any alternative oil of any kind as road fuel without paying fuel duty on it (including veg) - just getting that in before its pointed out - but the fake heating oil tank holds 1000 litres, at £400 a fill....and worked perfectly in my diesel van. I didnt have oil heating btw...

you can use straight veg oil from the bottle. the bosch fuel system which your engine has turns out to be the best ever

tesco superstores 20 litres for 15 quid

if its old chip oil it WILL have to be filtered before you put it into your car,
but you can just put new veg oil into your car now its summer (dont do it in winter cos the oil thickens and it gets harder starting engine)

sum1 i know puts straight veg oil into his 1.9td 306 (same engine as 406)
he's done this for 4 years and engine runs perfect (few fuel filters mind)

Okay, you got some important stuff REALLY wrong there.

1. White spirit, totally illegal to use this in a road vehicle in any way shape or form. Cheaper to use petrol anyway. Illegal as in big fine & possible loss of car.

2. Duty payments. As a private individual you can LEGALLY use upto 2,500L per rolling 12 month period before you have to pay any fuel duty. So the typical user would be running duty free all year. Legally.

Been looking on youtube people add white spirt to loosen the oil, so can use in winter aswell, so just buy from tesco and chuck it straight in the tank. Feels a little weird to chuck cooking oil in the fuel tank. But done some research and diesel engines were desgined to run on cooking oil before normal diesel became readily available.

Just to state it again, using white spirit in a road vehicle is illegal. Revenue & Customs will clobber you for it. People use petrol (which is cheap!) to thin the oil, but if you have a Bosch system, it doesn't need thinning.

[adamr8965]

How can you tell if you have a bosch system? its just a 1999 1.9td

firstly, I didnt say it was legal to use white spirit as fuel at any point, I just said it works to emulsify the fat in used veg oil, and it does.

and when you buy heating oil (and I have) it says on the invoice from the supplier that it is illegal to use it as road fuel without paying duty.

where does it say you can use 2,500 litres of anything as fuel without paying fuel tax legally? If thats the case then I will buy a car that can run veg oil

Adding white spirit to oil doesn't make an emulsion, it just thins it out. And it's quite hard to take the white spirit back out afterwards so you can pour the oil into your car

The 2,500L thing is common knowledge, been running for ages now.

They got bored of of processing the payments from the thousands of people who used 2L of veg a month and were sending in a cheque for a quid, they were losing money on it, so they scrapped duty on low usage.

interesting, thats a seed for thought then if its not just urban myth etc but written down law then I'll be converting to veg asap (not the hdi obviously) but what i mean is a chemical emulsion, so the fat is dissolved into the oil.

I know why its added, to keep the fat in the oil from separating out in the fuel system. Ive seen it done and tested by the AA on top gear. Jezza is God you know

Anyhoo, clean veg oil sounds like a good idea if its legal to use that much, as 2,500 litres is obviously 200 litres a month for a year, twice what I use in diesel now, and i do a lot of miles.

[StevieboyTD]

ARGH, that bloody top gear piece was full of crap, the white spirit was added to thin the oil, not to make a chemical change.

The only way to remove the "fat" from the oil is to make it into biodiesel.
