My 56 reg 1.9 tdi is currently running on 10% biodiesel, will keep you guys posted as to the pro's & con's.

Car only done 20000 miles.

Did you have to change the fuel hoses with biodiesel safe ones?

My 2.0tdi has a sticker inside the fuel filler cap saying NO BIODIESEL

This is my first tank, no need to change fuel hoses on a 2006 car, yes the sticker says no biodiesel, but the euro 3version of this car was fine, I cannot believe much has changed for the euro 4 version if you can read between the lines.

Will only go to max of 50% though.

Looking at this EN spec biodiesel, its viscosity is no different to normal derv, and come winter will drop down to approx 10%.

Will keep you guys updated.

It's not the viscosity that's the problem, it's just the fuel lines are not designed to stand up to biodiesel which is more corosive.

I'd change them just to be on the safe side, if I were in your shoes.

Fuel lines in a 2006 car are fine, searching the internet, not one car post 1993 has had a problem with fuel lines failing through biodiesel use.

So far so good, engine alot smoother, everything else has not changed.

Did you make the Bio Diesel up yourself and how , or is it from a forecourt pump .

I buy from a local supplier, fuel meets current EN standard.

Update

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.
