Can the derv lovers amongst us use Biodiesel in the CR Octavia's?

I've been looking at the above link. 70p a litre aint bad but dont want my motor getting problems

Cheers

Qoute from website

The companies that have approved 100% biodiesel are VW, Audi, SEAT and Skoda. They have approved all their cars built between 1996 and 2004 on 100% use of â€RME†Biodiesel (Biodiesel made from Rapeseed) providing it meets the specification DIN41606 (which was later replaced by EN14214).

Hi

Check the inside of your fuel filler flap. Mine has a large NO BIO DIESEL sticker. 1.6 CR octavia

I'm sure from memory if you open the fuel flap it has a no to bio-diesel.....................could be wrong though.

Ive not got my car yet so cant check unfortunately.

Just came across the website and was looking into it.

The qoute in the first post says Vwag group aprove the use of biodiesel?

Thanks for the replies

I have the vRS CR TDI and it says NO BIODIESEL.

No you cant use 100% biodiesel in the CR.

However on certain models you can on the link below from Skoda there are vehicles that can run on 100% bioiesel

I asked Skoda UK about this - as the NO BIODIESEL on the inside of the filler flap got me wondering as the UK has a 5% biodiesel content in it's fuels.

They have said that Diesel fuel sold in the UK is fine for use, but other biofiuels (such as 100% biodiesel) is not and WILL damage the DPF / Engine.

Skoda say its safe to use upto 7% biodiesel mix with regular diesel.

My 2006MY PD140 has a NO BIODIESEL sticker inside the filler flap as well.

Bio diesel in a CR will wreck the rubber seals and the injectors along with the DPF......a very expensive mistake to make!!

There is a local company who run both there MK1s and 2s and Vito's on chip oil, we laugh at them when they get stranded

I've heard of getting your engine chipped, but..........

When they get stranded, are they left 'Crisp 'n' Dry'???

i noticed this the other day while filling up at morrisons, it states at the pump that there diesel has 7% bio diesel, and thought after filling up that the filler cap states no bio, my car is the last of the pd units on the fl octy.

Its a no no with a dpf. The system injects a very small amount of diesel in at the end of the burn to go & heat the dpf (ever wondered why the mpg with a dpf is less ?) some of this will wash down the bore & as normal diesel is mineral based it mixes with engine oil without a problem. Bio diesel is vegatable & will be detrimental to the engine oil over time & thus shorten engine life. The quantities are small but over thousands of miles will have an effect.

So a DPF is good for the environment because :-

1. it stops soot particles, downside is the particles now produced are much finer & there is now a train of thought that the lungs cant filter them so they may be going straight into the blood stream.

2. it stops cars using eco friendly bio diesel

3. it reduces mpg by up to 20% so we are using up oil even faster

All in all great legislation, dont you love the Eurocrats, perhaps if they allowed the fishermen to land all the fish they are forced to dump dead in the sea we could add fish oil to diesel ?

My research tells me the DPF problem is the BioDiesel stays in the sump oil because it has a higher flash point (130C instead of 75C for mineral diesel). If the engine DPF burnoff is actioned by pre and post DPF pressure sensors only, their will be minimal impact as the high % biodiesel (b100) is essentially sootless. If the DPF burnoff is triggered by distance travelled (300km is one figure quoted) then the sump gets a small drink of biodiesel every 300km. If your oil change cycle is 15000km then that is where the damage might occur. Some choose to increase the frequency of their oil changes, Others take out the DPF and recode the ecm not to 'burnoff' (probably illegal).

I'm about to take delivery of a new 2009 Superd CR2.0 and will 'test' the sump oil fuel levels often whist running b100 SoyDiesel. If there is a problem I will drop back to b20. If there is still a problem I will revert to mineral diesel.

The experience of tdi forum contributors seems mixed with the cr engines.

I have successfully run b100 on my PD1.9 Octavia without any problems for 40,000km using routine maintenance. It does not have a DPF.

My SoyDiesel is EN 590 Certified
