Ive being reading about used veg oil and my head is spinning with all the diffrent things i've read on how to mix and use i can get a small amount every week 10L max. Can i just filter it  then pour it in my ford fusion tdci without adding petrol ect the car is a 2003 all i would have to do is filter it then let it settle and get rid of any water use the rest apart from any junk at the bottom. a yes or no will do pluse will it cause any harm to the engine and filters? thanks for any help you can give

Sorry  - i dont think its a yes or no question.
Think of it as a sliding scale including factors such as temperature (time of year), how runny the oil is at the start, how much you dilute with diesel/petrol, how much you settle/filter. How tolerant your cars setup is to veg.
Greater dilution = less problems.
Thinner oil at ambient temps = less problems.
Better filtered oil = less problems.
Older setup (ie mechanical injection system) = less problems
Inline fuel heating = less problems.

NB - VERY BASIC, GENERAL RULES ONLY!



If you just want to have a go then start really cautiously and increase the amount of fat you put in gradually untill your nerve goes or the engine complains.
Have a new fuel filter ready on yer shelf cos at some point you probably WILL need it.
If you break your fussy modern car find youself an older Xantia TD or Pug 405TD with Bosch pump and just push the chips right in!

Have fun!

Even more general rule:

Mechanical Injection:
Older CAV injection pumps - yes it will work, but be careful, pump is not too tolerant
BOSCH injection pumps - Yes, works well

Common Rail (ie electronic) injection:
Very risky UNLESS you first converting car with lots of preheating equipment.
