Anyone running their Octy2 on biodiesel ?

[Mr L]

Hi, is anyone here runing their Octavia on biodiesel (B100) ?
If so, is it a 2.0 or a 1.9 ?

I'm seriously looking at an Octavia but want reassuring that people are running theirs on B100 OK before I buy one.
The A3 we have has been OK for 2 years on it, but the turbo has just gone and the garage is blaming the biodiesel for it

Cheers,

Mr L

Hi, Bought my 2.0 140 Estate 1.3.08 and on the inside of the fuel flap is a notice that bio diesel is NOT to be used. I swapped this car for a 2006 Superb which had a particle filter in the exhaust system, and that had the prohibition notice on the fuel flap and in the handbook too. The Octi doesnt have the particle filter as far as I know, but they wouldnt put the notice on the flap if you could use bio, so I`m certainly not risking it even to save money and the environment.

Is that why Stella cost more than Diesel ?

exactly, all these eco geeks might be saving a few tree's somewhere but they are killing the rest of the world by making everyday essentials overly expensive, money grabbing farmer ********.

If biodiesel killed your turbo, then there's a serious problem elsewhere. Unless turbocharing a diesel is unique on the Audi where fuel passes through the turbo.

Thanks all for the replies.
1) I only use biodiesel made from waste oil. I don't believe in using new oil as it only pushes the price up, plus unscrupulous companies / farmers in other parts of the world are cutting down forests to grow crops for it which is probably more damaging than burning dino diesel.
2) Most farmers are genuinely poor, partly ( I believe) because they haven't been allowed to grow what they think they can get the most money from due to EU restrictions. I think they should have freedom to grow what they want and let the market dictate what will be profitable and what won't be.
3) The theory on the biodiesel wrecking the turbo is not proven, the only 1/2 sensible suggestion so far is that unburnt fuel in the exhaust gas has damaged the vanes / seals. Without stripping it we won't know for sure. I've not heard of anyone else having this problem and I think it is just the garage blaming the biodiesel because they prefer to stick with the oil based stuff that they know & love.
4) BMW also put stickers on the fuel caps saying no biodiesel, but the only reported downsides so far by people running bio in them anyway is increased consumption on bio, but it returns to normal on dino. They are so much thirstier that if you are having to pay for your bio it is not financially viable.

So is no-one running an Octavia on bio then ?

Bear in mind, the Octavia (and most of the VAG systyems) uses a completly different system of delivery than what BMW and most of the other companies (VAG use unit injectors (PD) while the others (inc top Audis and the brand new VAG engines) use a common rail system of fuel delivery) plus they do not all use the same make of injector either.

so what is good for the goose is not necessarily good for the gander.

Hi
I work in the fuel injection industry.
One of the main reasons that manufaturers dont like biodiesel - is the fact that, unless it is very recently manufactured - it deteriorates very quickly.
It breaks down into chemicals - which potentially ruin the fuel injection system.
Anyone who has tried to start a lawnmower with old petrol - knows what stale petrol is like!!!
Stale Biodiesel is apparently worse!!
Cheers!

Is the 2.0 that much different to the 1.9 then as far as the injection system goes ?

Yup, injectors are completely different, Piezo injectors are much more accurate at the ammounts of fuel they deliver. Mounting is also different as the 2.0 is a 16v engine, 1.9 is 8v (unless you have a 2.0 Superb).

Recently ran my 2.0 octavia on 70% highly refined BioDiesel with no problems. Go figure

Are you sure its the turbo thats gone, it could be the MAS that has packed in it give similar symptoms

[TorqueDude]

Does anyone know whether there is a 'no boidiesel' restriction on the new CR Vrs diesel engine?

[stu4rtparker]

Been runing on 10% with no problems, my fuel filler flap does say no Biodiesel, but my handbook clearly states that 30% is OK providing BD meets EN14214, I have also had this confirmed by Skoda UK, email below

Dear Mr *****

Thank you for your most recent email regarding your Octavia TDi. I am pleased to learn that your vehicle is able to use a 30% blend of RME Biodiesel.

When designing our more recent models, there has been a lot of focus on increasing fuel efficiency and decreasing the carbon emissions released by our vehicles. The new technology and parts used are not compatible for use with 100% Biodiesel.

We want to play an active part in cutting global emissions of Co2 and we are committed to Biofuels. We have major projects underway to produce second generation Biofuels which we call Sunfuel. Sunfuel refers to sulphur- and aromatics-free diesel and petrol that emit far fewer pollutants on combustion and these second generation fuels offer the best platform for economic and low-emissions engines of the future.
