On another bulletin board, people were whining about diesel prices, and somebody posted this easy "recipe" for biodiesel:
Quick and easy quasi-biodiesel recipe:
15 gallons used veggie oil
5 gallons Kerosene
1 gallon Gasoline
1 pint Heet
Mix. Filter through two household water filters (5 micron) until it looks and feels like diesel fuel.
-----------------------------------------------------------------------------------------------
If you get your oil free, this should be under $1/gallon. No modifications to the truck are needed.
The person who posted it claims to know someone who has been running a truck on it for a year with no issues. But I'm a little skeptical. It seems like if it was really this easy, all the folks who are using much more complicated processes would have caught on. I don't know much about creating BD, but from what I've read here, glycerine removal seems to be important, and this doesn't seem to allow for that, unless they're catching it in those water filters, which doesn't seem likely.
Any thoughts? Is this a good way to save money, or a good way to ruin an expensive engine?
