Default Add used oil to diesel fuel?

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

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.

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.

I would be diluting it into 320 gallons of fuel.

Is this common?

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

John,

In the fleet application I used Racor's system which included filtration.
On my personal diesel vehicles I simply added the oil directly from the
crankcase to a nearly full fuel tank. My reasoning was that the lube oil
was well filtered by the oil filter and that the after market Racor filter I
always installed in my vehicles' fuel lines would do a good enough job of
removing anything harmful.

The Racor systems were not inexpensive but paid for themselves over time
several times over. If I had a diesel boat I would have a Racor system or
make up an installed one with a pump, some tubing and fittings, a valve or
two, and a filter. Can you imagine an oil change on a boat with no mess, no
oil disposal issues, and improvment to your fuel economy. The only issue
would be the filter change. You could do it just like the pros.

The correct way is to run the used BaseOil thru a Centrifuge first, then
thru a 2 micron filter. We have this system in our 2.5 Megawatt
Powerhouse, and burn the resulting lubeoil in a Waste Oil Burner/Heater
in the Port Engineers shop. The residue that comes out of the
centrifuge is Classed as Hazardous Material, and we ship it to a
recycler.
