I am picking up my felicia diesel tomorrow, the question is does anyone run theirs on diodiesel, i read this today.

Biodiesel, in theory, can go into all diesel engines as the diesel engine itself was designed to run on plant oil. However it is the parts attached to the diesel engine which could potentially cause problems – although the vast majority of diesels on the road are fine running on 100% biodiesel. In reality, the rule of thumb is you can use 100% biodiesel in any diesel built between 1990-2004, but be aware that a one-off fuel filter change will be needed after you first make the transition (and any mix of biodiesel and fossil diesel is OK too). I would recommend that cars built after 2004 should run on a 50% blend not 100%. Be aware too that biodiesel made from waste cooking oil will freeze in winter and so from November to April one should blend that kind of Biodiesel at 50% as well. However, Biodiesel made from a Rapeseed crop (RME) will not freeze and can be used at 100% all year round in the UK. Please note that it is advisable to purchase biodiesel with EN14214 specification, that gives you some guarantee of quality. In short – to be safe, use RME Biodiesel at EN14214 in a car built between 1990 and 2004 and then you can be carbon neutral all year without problems!

In terms of official compatibility, despite the majority of diesel vehicles on the road being fine on 100%, only a handful of companies will officially approve their vehicles for 100% use. 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 ”RME” Biodiesel (Biodiesel made from Rapeseed) providing it meets the specification DIN41606 (which was later replaced by EN14214). These companies can still provide some brand new cars warranted on 100% biodiesel but one has to request it (best to get the official letter from German Base as some UK agents aren’t fully aware). As these companies have officially approved 100% biodiesel I urge you to use your consumer power to support them in supporting the environmental movement.

I read that it takes an input of more fossil fuel energy into creating biofuels than can be got out of them in an engine; what with tractors, pesticides, fertilisers, processing & transportation...

My brother uses his own biodiesel............corn or vegetable straight from costco in his citreon xm. Its still miles cheaper than normal diesel. He uses 50% diesel and 50% finest vegetable oil.

Runs like a dream. The main issue with biodiesel is whether there is a direct or indirect system. Indirect is best with primitive engineering and no ECU.

You can put it in the Skoda i believe but i think you will need to get the quality right first.

"Biodiesel" is the pump bought stuff, hence the EN14214 specification Biodiesel - Wikipedia, the free encyclopedia rather than good old SVO (Straight Vegetable oil) Vegetable oil used as fuel - Wikipedia, the free encyclopedia

Biodiesel Approval

Lucas pumps sieze up using SVO and they're fitted to Felly 1.9 D lumps, so a blend is necessary.
