I blew it.

On the straight "previously used" vegetable oil, the oil was filtered,
but otherwise not tampered with. The Mercedes diesel got 30 mpg, not 33
mpg. The 33mpg was on regular diesel fuel. Even so, that is pretty
impressive. In a pinch, you could go into the grocery store and buy
enough vegetable oil to get to where you wanted to go.

I wonder how the German diesels if installed in a Vanagon would handle
the vegetable oil.
