why no biodiesel?

[alhendo1]

Hi folks.can anyone tell me why my octavia 1.9tdi 06 plate(new shape) is not allowed to use biodiesel? someone I know reckons its dueto a diesel particulate filter. can anyone shed any light on whether this is correct andif not why can't it be used.thanks.:confused:

don't know the answer to your question but neither the 1.9tdi or 140bph 2.0 tdi has a DPF

I used B20 in my Golf 2.0Tdi which has now done 56000km and runs super economically = 4.7L/100km on trip. My new Occy 2.0 Tdi is going to get its first injection of Bio today - I buy 100% Bio and put 500 - 600ml per tankful into the tank - this gives a 1% mixture which gives a substantial reduction in engine wear particularly if you are using Ultra low sulphur Diesel ( < 10ppm ). In South Australia we have a " Premium Diesel" blend which is 20% Bio in summer and down to 5% in winter depending on how cold it is. Because it meets and exceeds all government standards for Diesel the manufacturers have no reason not to allow it. The main hazard of using straight Bio is the sudden cleaning of your fuel lines if you have used lots of petro distillate or deterioration of unsuitable rubber components in the fuel line.

Something to do with the fuel injection system and the viscosity of biodiesel. As you can tell I'm not a mechanic, but I sure someone on this site will expand further!

This is the link for the FAQ on Biodiesel in South Australia

Apparently you cannot use this type in PD engines as it fooks them up (so i have been told)

[durhamfisher]

It will almost certainly invalidate your warranty if you experience any problems with the fuel injection system in the UK. Maybe the terms of the warranty in Australia are different? Biodiesel seems more available / controlled than in the UK at the moment from the link provided.

I also dont know why not biodisel in pd engine, but in Europe (my case Slovenia) you can original order ordinary disel engine with addinotanal eqipment to tank biodisel without any problems.

I know that because I noticed this optinal when I ordered companys cars. We have 4 Octavias in company.

Found this document:

Which says it can duff up your dpf, if you have one.

However, it looks like other countries are leading the way on green fuels, where as the UK's approach seems to be tax the life out of us all to encourage us to buy VW polos and fiat puntos. Oh yes, and to use the non existent public transport infrastructure.

Now where did I put that passport........

[alhendo1]

thanks to all who posted replies. I suppose on the strength of whats been posted I'll just stick with the current overpriced offerings on our forecourts..........

Where ever you go, do not to come to Norway! You'll get even worse "bombed" with car-related taxes over here :eek:

Its something to do with the viscosity in PD engines, and fuel seals being 'eaten' by the fuel in all engines.

I believe that the older 1.9TDIs can take it though.

[VRS195]

The PD injectors cannot handle the sludge build up from bio-diesel.

I shouldn't worry, good old "Green Budget" Brown has quietly abolished the biofuel subsidy anyway.

Budget 2008: Biofuel subsidy surprise

By Russell Hotten

Last Updated: 1:00am GMT 13/03/2008

The Treasury aims to raise £550m through the abolition of a biofuel subsidy in a move likely to undermine Alistair Darling's claims that he delivered a Budget for the environment.

Fuel producers, including giants like BP and Royal Dutch Shell, get a 20p per litre discount for selling biofuels. But this is being abolished.

Fuel producers currently get a 20p per litre discount for selling biofuels, the subsidy was introduced to encourage development of alternative fuel sources, but has now been condemned as a revenue-generator for the Treasury.

Ruth Dooley, tax partner at Grant Thornton, said: "Given the green statements made by the Chancellor in his Budget speech, it is a major surprise that he is penalising biofuels by over £500m without making any announcement either in the speech or in a press release."

Details of the change were buried in the Red Book, the Treasury document that accompanies the Chancellor's Budget speech. In the document, the Treasury says that its new tax treatment for biofuels "will provide a sharper environmental focus through its sustainability criteria".

oh dear!

that's what gets me... the Governments are bleating on about 'Global Warming' and yet these modern Diesel engines cannot run on Bio.. is it just me or is something amiss here?? as we try to cut down on our 'Carbon Footprint' by using Bio.. the car industry seems to be either lagging behind with design or are just not interested in using Bio in the future??

Rant over..

Cheers

there is no sludge build up from Bio Diesel quite the opposite. Bio Diesel removes the wax and heavier weight hydrocarbon build up - if you have been using Dino fuel and you change to Bio you will need to change your Fuel filter at least 3 times - once after each successive tank full to remove dino sludge. As far as particulate filters go their effectiveness also depends on your driving habits - if all your trips are short then avoid Bio - if you do a good quick 50km highway trip per week that should get the system hot enough to burn the DPF clean - if you don't have a DPF there is no reason why you shouldn't use a 10 - 20% Bio mix - it significantly reduces engine and fuel pump wear esp. if you are using ultra low sulphur Diesel 10ppm or less

Seconded. Saved me some typing!

[Daz 262]

So why are Skoda in their handbooks stipulating that Bio should NOT be used??

The whizz kid on this appears (no slight intended) to be Decron.

Perhaps do a Search and read up on what he says.

He is some kind of 'fuel scientist' .
