Is this common?

The better practice would be to save the used oil and take it to a
recycling station.
On a long voyage, you may wind up with a few 10-gallon containers of
used oil.

Pouring the used oil into your fuel tank *will* work, but why introduce
all those contaminants into the fuel system?

Wouldn't have been a problem in older diesels, but I wouldn't do it
with the new high output types, with high pressure fuel delivery, etc

Lots of opinions with little in the way of facts.

The practice of burning used diesel engine crankcase oil as fuel has been
popular with fleet users for many years. The main caution is that the oil
must not have been contaminated by coolant. The practice will not void the
warranties of any of the major engine manufacturers. The lube oil is burned
completely and, BTW, has a higher BTU content than fuel oil.

The process should be done carefully in order not to "over oil" the fuel.
Racor, the filter manufacturer, used to sell a system for the purpose. I
bought several for a fleet of large EMD, Cummins, and CAT generators. The
systems made us a lot of money by saving the cost of disposal of used lube
oil and avoiding the cost of thousands of gallons of fuel oil. The Racor
kits were in several sizes to accomodate small to large applications. I
don't know if Racor continues to market the systems.

But weren't these mostly mechanical fuel injection?

Bill,

I'm not sure I understand your question.

But, all diesel fuel injection systems are mechanical. They are also
hydraulic. New systems use digitial electronics to more perfectly control
the hydraulic/mechanical action to more perfectly inject the precise
quantity of fuel required at the precise time it is required. This serves
to more completely burn the fuel and to eliminate the unburned hydrocarbons
so problematic with older poorly maintained systems. The byproduct of these
improved systems is vastly improved fuel economy and improved longevity of
engine upper deck components.

I continue to advocate recycling used diesel engine lube oil as fuel.

YMMV.

Butch, how do you filter it before adding it to the fuel?

All diesel inject is not mechanical. The new engines, like my Duramax or
Eisbocks Ford 6.0 are electronic FI. There is a high pressure, precision
pump that generates the high fuel pressure to a single fuel block, the
single rail. The Electronics pull the solenoid and allow a precise amount
of fuel to inject. My duramax does 3 shots per power stroke. The old
Detroit Diesels, etc had a mechanical piston to inject the fuel. You
adjusted the "Racks" to get the best fuel burn on average. Was to early at
idle, why lots of rattle (pinging) at low RPM's. Probably bigger jets in
the injector also. Only one shot per power stroke. The new pumps will be
close tolerance and smaller holes in the injectors. You would have to save
a lot of money on diesel to pay for the repair of either the pump or the
injector. Lots more for the pump.

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.
