biodiesel

Why ?

I'm not being argumentative - you maybe right but I'd like to hear factual reasons otherwise its just an opinion. I'm an engineer by profession in the chemical industry so have a reasonable grasp of machines, materials and chemical processes. IMHO I can't think of anything that would prevent any diesel engine running on biodiesel.

So if there is a good reason why the Mk2 Leon can't run on bio then I'd like to know because it would be the only reason I wouldn't trade up from my Mk1 - Seat has been good to me.

me neither just not a risk I want to take - buying a car worth more than a years wages, I cant afford to fix it if it goes bang outside of warranty. All the documentation from VAG says bio is unsuitable and I reckon they should know . . . . . . . There may be agendas or political reasons to say this when it isnt true but personally Im not prepared to take even a calculated risk. At 42mpg on £1/litre of derv I cant say its expensive to run anyway.

That's fair enough If I wasn't doing so many miles I probably wouldn't be bothered either because its a time consuming business.

My missus bought a Jeep Grand Cherokee this weekend and thankfully it took to bio no problem at all which is a good thing since it only does 24mpg

Hi, hope I can join in the discussion! Just a word of caution for anyone thinking of using a high percentage of bio-diesel in a car fitted with a DPF.

When the engine management system is actively cleaning the dpf, fuel is injected after top dead centre, this fuel vaporizes in the filter raising its temperature so that the trapped soot can be oxidised.

Some of this fuel can wash down the bores into the sump, normal diesel should then evaporate back out again during a longer run. The problem with diodiesel is it has a higher flashpoint and is less likely to evaporate. The end result is thinning of the engine oil with the potential for premature engine wear.

At the very least the engine oil should be changed more often, but is it worth the risk?

bio definitely makes sense on low mpg vehicles - hopefully in time it will be the new lpg

Does anyone know the current resell rate for used vegetable oil?
