In an ideal world, I would like to have my Diesel benz with an optional fuel tank/line that would also allow WVO/SVO. Is this possible?

Not that I would not mind going 100% WVO/SVO, but the option between Diesel AND WVO/SVO would be even nicer.

That is what my vision is, and that is what I am striving for.

Gonna go ready through that Sticky on WVO/SVO/Biodiesel now...
