Wvo

[Hanomag]

I am curious how many of you run a two tank system with filtered WVO? I know that the Mercedes have been known to do well on the stuff and I would assume that the D24T should also perform well but I would appreciate some real world experience. It seems that if one could find a good source for oil and then filtered it down to about 5 microns and had a reliable two tank system you could drive for next to nothing.

How long does it take before the oil is warm enough to switch over?

Do the inline heater pads help to switch onto veggie sooner in the real world or extremely cold weather?
