Last time I checked. Five gallons of the cheapest veggie oil at Sam's Club was $4.00/gallon. But you need to heat it up before it will work in a regular engine(you have to install a pre-heat tank). If you remove the glycerin( make it into biodiesel) you have to add the cost of lye.

I was actually thinking more along the line of 500 gallon quantities. I wouldn't bother using it in my truck nor even converting it into biodiesel. After many, many years of wrenching I no longer have ANY desire to work on my primary mode of transportation. But as a replacement for home heating oil or for stationary/off-road engines, that's something I'd consider.
