Bio is only normally 5% bio, as if too much bio as it has such a wonderful cleaning action can indeed block things up, I used it in my old escort diesel, and it defo went better.

PassionFord Post Whore!!
being a biodiesel engineer, thought i'd give you my opinion on the topic
first check with ford as to what level of bio they warrenty, some only do up to 5% (which can be found in normal fuel nowadays) some cover up to 30% and a small majority up to 100%
second, check the source of the fuel, what feedstock it comes from, pure grade RME (rapeseed) is much better than say bio made from recycled vegetable oil, and make sure it conforms to EN14214
confirm what they mean by biodiesel, as tabetha says, it could be only 5% but PROPER biodiesel is 100% organic and contains no diesel
to reinforce what tabetha says there are these main drawbacks with biodiesel:
1) it is highly solvent so will clean tanks, lines, and pumps. so expect to need to change the fuel filters
2) poor spec fuel can have bad cold flow properties, cause poor starting, and gel up tanks in winter
3) there is a slight power loss between normal diesel and 100% biodiesel

PassionFord Post Whore!!
dont take this as scare mongering, but find out about the source of the bio first and make a decision from there
if it costs 20p less per litre, then on a 80 litre tank you would save £16 everytime you fill up
theres plenty of forums where people share their experiences with bio and different vehicles
just google it

Did wonders in me old agricultural escort 1.8 non turbo, defo quicker and a lot smoother.
I do know there is a growing disquiet among diesel owners about broken down diesels that have become BLOCKED, due to BACTERIA in the underground storage tanks, this mixes with certain bio's depending on what type of bio they are and forms into LUMPS that go on to block any pipe etc they contact.
This is essentially because the underground tanks are not clean, so there may be some urgent action, on petrol/diesel forecourts soon!!

Tried bio diesel my old tranny Di, it went ok but on new rapeseed oil (50/50 mix)i get more MPG and it runs soo much smoother you'd think it was a new engine (not a new Di i meen it sounds like a modern diesel IE quiet)
I take it oil looses calorific value after it's used? i put the extra power and MPG down to new oil have a higher calorific value than straigh diesel or reclaimed ? (one for gingeRS ) ?

I use new veg/rapeseed oil in two of my motors, and it works a treat, eng runs smoother, slightly better performance etc & the main thing its cheaper than diesel!!!
