Just wondering, how much crud is left behind after the filtering process?
Not a lot actually, what I hear you have to do is use Methylated Spirits and Caustic soda, approx half a tea-spoon per 1 litre of grease + 1 cup of meths, then you shake it like hell, wait 24 hours for the Glycerin to separate siphon that off as its worthless then chug the rest into the fuel tank.
OMG, people actually use face-book? There was me silently thinking Google Plus + was the new hip and in thing. Social networking, it couldnt be more anti-social, have any of these people heard of Alexander Bell and a thing he invented called a Phone!
Happiness is twin floppies.
