Biodiesel question.

Should be better, as it is generally higher octane and better lubricity.
Sometimes causes blockages of filters and such but I've not noticed reduced econmomy

If he hasn't replaced his fuel filter, I'd suggest his fuel filter is clogged with the rubbish that has collected in his fuel system over years of dinosaur diesel.

I did replace my fuel filter after the first tank, and the collected deposits are quite evident. Now my economy seems better - but I don't have too much scientific data to go on.

Would strongly recommend he do that if he has not already?

Ciao for now

AFAIK this is fairly normal, but it should be more than offset by the cheaper price of biodiesel. Is is cheaper isn't it ? Or is this just another example of having to go into the red to be green ?

Although Biodiesel has higher lubricity and is better for the environment I recall reading somewhere that it actually has a lower energy value than ordinary diesel. This makes sense to me, as every time I have tried it, I get poorer fuel consumption figures, and noticeably less power under the right foot.

Wonder how they go with common rail diesels - which use much finer nozzles. Filtration is a much greater issue with this type of injection system...
