I have just been to Morrison's where they had both diesel and biodiesel at 119.9 a litre.

Can biodiesel be used in the 1.4 Tdi 80 engine?

its 118.9 at my morrisons

As far as I know, NO.

Oh dear -what have they changed in the new engine -my MK1 14Tdi 70(5) handbook says that any bio conforming to spec bla bla can be used .I was even thinking of a 50/50 mix with bio @ 80p and diesel when it was 132 ,but cost of new filter sort of changed my mind .

I thought biodiesel was supposed to be cheaper...

Just stick a 50/50 mix of diesel to cooking oil in!!

Please do a search.

Well covered topic. You car will not run on a 50/50 mix with veg oil, the whole system will struggle with it. 20-30 % in this weather is ok, going to 15% in the winter.

Morrisons Bio is only B30 (And this is 30 % Bio which is different to VO) so I don't see a problem

Don't forget...virtually ALL diesel sold at the pumps has at least 10% Bio in it already. This was a government target set some years ago, and it has been achieved. This was in order to further reduce particulate matter and other nox gases. The new target now is to be 15% minimum of each gallon sold will be Bio within the next 5 years.

Bio diesel cheaper? If you could run car,s on fresh air this goverment would tax it !!!1

It's become so difficult for BD producers to sort the tax out a lot of them have just given up

whats bio diesel??? :confused:

I'm sorry. Environmental benefits or no environmental benefits, if biodiesel is as expensive as normal diesel then I'll buy the normal diesel every time.

Why?

Does the fact that the elder diesel engines are incapable of running correctly even on a 50/50 solution not put you off even slightly? I'd rather feed my car the food it was designed to eat, and tested to tolerate...

Older as in Pre-92 cars have issues with rubber hoses (As opposed to plastic in newer ones) which will rot with Bio exposure. Other than that Biodiesel is exactly the same and conforms to the same spec as regular mineral and can be used in place of in a lot of vehicles.

WVO (Waste Veg oil) is different again as it's not processed like Bio and is therefore cheaper however it's a lot thicker and this causes obvious problems. People who are dedicated to doing this will have their car converted with either a heat exchanger to thin it out or run a twin tank.

You VRS will run on 100% Biodiesel and about 25% WVO. There are lots of reasons why you shouldn't and lots why you should, it will depend on your situation. I save about £3.27 on each tank of fuel using a 25% veg oil mix. This works out at about £200 a year saved and I give a less tax to the muppets in power.

BTW did you know that the first "diesel" engine was actually made to run on penut oil.

I meant the elder ASZ VRS engines, I was under the impression that running the engine for prolonged periods of time on veg oil or biodiesel caused damage to the fuel system.

Another reason I'm reluctant to do it is because of the nature of the PD system. If for some reason my injectors become damaged using biodiesel, I'll be well and truly fecked - I hear they're an expensive repair job.

I do concur though that if I had a less valuable car that I didn't plan on running for a long period of time, I would go for the biodiesel. In my current situation I will go for "proper" diesel every time.

My 55 plate VRS did 55k on it without any issues. There isn't a lot to go wrong if the fuel is up to spec.

My 04 handbook says the same -Bio must be to spec *****,otherwise damage to the fuel componants will result .

Fair enough, but still, unless there is at least some financial gain (5ppl? 8ppl?) what motivation have I honestly got to try it?

If you start harping on about environmental benefits then I'd love to introduce you to the nice big (probably conventional diesel burning) tractors that had to:

a) Plough the field

Work the ground down

c) Sow the seed

d) Cut the crop

e) Transport the crop

. I don't deny that as a sustainable fuel it is probably (well, it is..) better than conventional fossil fuels. But at this moment in time, unless the use of it in my (beloved) car benefits me financially in some way then I'm going to be steering clear.

My original post wasn't questioning the value of Biodiesel but explaining that for as long as they're the same price, I won't be going down the BD route

Yeah thats what I said. It actually needs to be up to EN590 (EN590:2000) which describes the physical properties that all diesel fuel must meet if it is to be sold in the EU, Czech Republic, Iceland, Norway or Switzerland. It allows the blending of up to 5% Biodiesel with 'normal' DERV - a 95/5 mix. In some countries such as France, all diesel sold routinely contains this 95/5

£3.27 a tank as I have mentioned. May not seem like a lot but it's about an extra 40 miles per tank for me

More or less irrelevent in my case as I burn WVO so all I am doing recycling and riding the world of a waste product. That way there are no moral or environmental issues.

Like I said there are many pros and cons to this and it will all depend on the situation. However, it does help if everyone is well informed...

I appreciate that, I just want to make sure that people have the full story so they can make an informed choice I have been running WVO/Bio/Rapeseed for 100,000's miles in various cars and I think if you put the effort into it, it will save you money.

My 1.9TDi has a sticker on the inside of the filler flap that is pretty clear -

A big red circle with a line through it over the words Bio-Diesel!

The Morrisons just down the road from me has Bio at two of it's pumps. They've put a sign next to them to say only use it if your manufacturer has said you can otherwise you may damage your engine.

There's normally a queue at every pump, except these two where you very occasionally see a van or taxi filling up.

If you have a DPF you should heed that lable, if not don't worry about it.

I think I will give biodiesel a miss. My old Fiat would take 100% veggie oil with no problems at the time it was about 73p a litre.

Red Diesel anyone ..........

Too smoky for me.

Who told you that red diesel makes your car smoke? It's amazing what bull**** goes around.
