[Vwdiesel] Burning Used Crankcase Oil

[82 Diesel Westy]

Sounds like a great way to get rid of the old stuff,
but our recyling placed in NJ take the oil, so not a
big deal.
So mixing a gallon or two of CLEAN used oil from the
car to a 5 gallon diesel tank, shake and put it back
in the car/truck/vanagon tank in Summer.  So that
equates to about $6 bucks here in NJ for fuel savings
and lessons the cost of my oil change because I save
both ways but putting the used oil back in the tank.

I like it.
