i've heard of plenty of guys here running WVO straight in one tank, and switching to clean #2 for start up and shut down, and i hear they have no trouble with it as long as they have proper heat systems and all that, which it appears you do/will
for WMO, i often run it at 50-75% with no trouble at all, and i'm only filtering it through paper filters, i've heard of guys with a centrifuge running it up around 90% or so. as a general rule, the greedier you get, the more likely you are to run into problems, so i would suggest keeping it in the range i run.
