22mpg from 5 gallons WVO with one gallon of diesel mixed in sounds reasonable to me. Alohaspirit may not have been exact in stating his assumptions, but it looks like you are making some that are not justified. He is not making unreasonable mileage claims, but perhaps only a misunderstanding in MPGe.
The indirect injection of the OM616/OM617 is quite robust. It operates at low pressure, can deal with highly viscous fuel, and due to the prechamber has very few issues with partially combusted fuel getting into the rings. With diligent oil changes, this engine is head and shoulders above modern direct injection engines with regard to fuel tolerance, and is extremely easy and inexpensive to service as a result.
VO is an excellent choice for a Hawaiian W123, it loves the VO, the climate is perfect and biodiesel ingredients are more expensive than elsewhere in the US.
