Of Diesel is the key part of that sentance. Take into account the time it takes for WVO to heat up before you can switch over to it, and the OP is saying that longer trips is the larger pay off. Essentially you should only be running diesel when you are waiting for the warm up.
Skoot, why aren't you considering bio diesel? I also agree that it is the most practical solution.
