I'm not sure if this is appropriate for this forum; I have been following
articles on bio-diesel in
Home Power magazine and find it very intrigueing. I have read that once you run
a tank or two of
bio-diesel you must change out the oil and fuel filters at least once as it
cleans out all the crud.
Does anyone know if you can keep switching back and forth between the fuels...?
I assume you can.

My understanding is that you can run on 100% Vegie oil.
But you need to start up on regular diesel then switch
over. So yes, you can keep switching back and forth.
Someone correct me if I'm wrong.
Just my $.02 worth. Hope it helps
Unity means let's try to meet each other halfway

yes, you can switch back and forth.
diesel and biodiesel are interchangeable, and can be mixed in the same
tank. veggie oil needs to be in a heated tank, but (bio)diesel can
coexist in the heated veggie tank if you needed to. don't put veggie oil
in an unheated tank.

The use of veg oil also depends upon the type of diesel engine you have.
Older indirect injection type engines are much better suited to veg oil
(pre-heated). The newer direct injection engines tend to have a much
harder time with pure veg oil, even when pre-heated. Pure veg oil tends
to cause coking and other problems on these engines.
There are some cos that are selling kits for some of the newer DI
engines which claim no problems, I have no experience with them. But
the simplier pre-heat systems used on DI engines seem to cause issues
over the long haul.

Have you used wvo in newer diesels? We are using it in DI engines with
no such issues as you portray. No, Newer DI's work just as well with
heated WVO as the older IDI engines did. No coking because startup and
shutdown on (bio)diesel prevents that from happening. Reading a web page
somewhere doesn't always enable one to give valid advice. Experience is
the best teacher.
