Many have commented and I would normally would be willing to mix the lub oil
with a high ratio of fuel oil. However, I have always been able to take my
lub oil ashore/home for disposal.

Now I burn all of my waste oil in my shop heater. I have an old Dickenson
cabin heater and when mixed with some diesel, it burns fine.

I'm now building a waste oil heater for my new shop, from a Mother Earth
design. It will only consume about 1 qt/hr and provide about 30k btu. No
diesel required.
In this design, the fuel feed is preheated and the fire will burn hot and
clean without soot or smoke.

Just my thoughts, FWIW.

I recently read something about adding the used oil from your crankcase (20
quarts from my engine) to your diesel tanks to burn up, thus saving the
purchase of five gallons of fuel and eliminating the problem of disposal.

I would be diluting it into 320 gallons of fuel.

Is this common?
