Was the [assumed reliable] information you gathered with respect to big

If yes, in what proportions gas:spent-oil ?

I'm told that big fleet users do this all the time. The correct
proportion is 20 gallons or more of diesel to 1 gallon of waste oil.
Ideally the waste oil should be filtered before mixing but if you have
a big set of Racors installed that is probably sufficient.

Friends of ours have a long range cruiser which has an oil recyling
system built in.

Another possibility is using it for home heating oil. My old auto
mechanic back in the northeast does that, just pours it into the tank.

It works like a charm if you don't mind loading the neighbourhood with
toxic waste products from the various heavy metals found in the engine
oil additives.

http://en.wikipedia.org/wiki/Lubricant
"Burning the lubricant as fuel, typically to generate electricity,
is also governed by regulations mainly on account of the
relatively high level of additives present. Burning generates both
airborne pollutants and ash rich in toxic materials, mainly heavy
metal compounds. Thus lubricant burning takes place in specialized
facilities that have incorporated special scrubbers to remove
airborne pollutants and have access to landfill sites with permits
to handle the toxic ash."

I know that the use of engine oil for home heating is illegal in some
parts of the world.
