Steve,

Sorry - that's not the point.

The point is:

 Will a salt agitation and a filtering process convert vegetable oil 'into' biodiesel. It seems unsurprisingly that it will not, in spite of some fictive nomenclature and some strange drawings of a weird molecular structure. It will though, no doubt, sell a few buckets and magic beads. The purveyors of the process never actually claim to be making biodiesel, they do however try to put it over as a viable compression engine alternative fuel. Of course even though the compression engine, now denominated the diesel engine, was originally designed to run on vegetable oil, most people have lost sight of that. So, basically what they are doing is messing unnecessarily with veggie oil diluting it with 'orrible fossil diesel and adding salt, then after thrashing the begeebies out of the mix and leaving it  to settle they're filtering the good looking portion through their magic beans and - viola - you got filtered veggie oil with some dino diesel mixed in.


I wont take issue with you on your percentages as true emission statistics are readily available these days. What is confusing though is the lack of awareness on the environmental cost involved in the actual manufacture of so called bio fuels. In The US it has become viable to convert corn into ethanol for fuel, even though the energy required to produce 1 unit of ethanol energy derived from corn is some 90% of it's potential capacity - depending on how it is produced and even combusted.

If you are looking for the best (even the most wallet friendly) and most environmentally beneficial fuel right now then go for wvo (waste vegetable oil) it's done it's job and paid it's dues, use it again. It is Co2 neutral, more or less. No heavy metals. No spill risk - etc. Don't buy a new car (making one costs a lot of energy as does junking the old one).

Biodiesel does lubricate a bit better than dino but it eats rubber and flushes your tank and lines - you should be aware of this.

If you want to drive on desulfured (less lubrication) Dino add a little veggie like the truckers do.

Or just re use old discarded veggie oil as your main and best environmental choice, I even get paid to haul it away sometimes =-O

Best wishes
KJ

     Thanks for going to all this trouble, I have had problems with the  concept from the beginning. If the whole idea is to lower the viscosity  of veggie then why not just filter and heat? Of course diluting veggie  with fossil diesel either before or after filtering will 'runny up' the  veggie to some extent if it's not too cold where you live and if your  veggie is not too contaminated - even so, I just can't see the point.   Bio diesel it aint!   /KJ   Nate wrote:  > O.K. guys and gals, as for me I won't buy into this new thing salt  > cracking.
