Makes me respect the strength of those little paper filters! A submicron filter or even about 2 micron plugs right away. The viscosity of the oil requires high pressure or strong vacuum. Then, you run the risk of rupturing the filter. Commercial oil recyclers use heat, acid treatment and filtration through diatomaceous earth to make their product. I've considered diluting the oil with a solvent, then centrifuging it to settle out the solids, then filtration and finally distillation to recover the solvent. That should produce a pretty good oil. But, of course, if you have to do all that, it would be best to reuse it, not try to use it for fuel. -- Jay [Non-text portions of this message have been removed] Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Biofuels list archives: http://archive.nnytech.net/index.php?list=biofuel Please do NOT send Unsubscribe messages to the list address.
