The reason for adding motor oil to diesel fuel is because construction and trucking companies who keep fleet maintenance records noticed premature failure of diesel injection pumps due to inadequate lubrication as soon as the feds forced the use of low sulfur diesel.
So the secret lubricity additives your 3rd party puts in diesel fuel are inadequate. By adding 1 quart of motor oil to each 200 gallons of diesel fuel the premature failure of injection pumps stopped and they have not had any premature engine failures do to combustion chamber deposits. A friend of mine even adds clean used motor oil to his diesels for lubrication and to save on fuel costs.
Having to purchase and install an injector pump is a major expense and in a SHTF scenario a new injector pump might
not be (edited to add not) available.
If anyone has a problem with combustion chamber deposits they can be easily cleaned with Sea Foam engine cleaner.

Sea Foam®, when used in Diesel fuel, cleans fuel deposits from the fuel system and carbon from inside the engine safely. It also adds lubrication and controls moisture when added to diesel fuel at one ounce per gallon. Another use for Sea Foam® in Diesel applications is cleaning fuel injectors. This is accomplished by getting engine to operating temperature then shut off. Remove the fuel filter (replace filter if needed.) Empty all diesel fuel from filter or filter housing and fill filter or housing with straight Sea Foam®. Reinstall filter on engine, making sure there is no air in filter. Start engine and let run about two minutes, then shut engine off and let sit about 5 minutes. This is called a “HOT SOAK” letting the Sea Foam® soak into the carbon. After the “hot soak” period, restart the engine and road test, driving aggressively for about 5 miles. This will clean carbon from the injectors and the combustion chamber inside the engine. Sea Foam® can also be used in oil for cleaning the crankcase. Adding Sea Foam® to your oil will clean oil deposits and varnish from your crankcase, free up sticky lifters and clogged oil control rings. Add Sea Foam® to the oil at one pint to 2.5 gallons of oil. Then drive, or run the engine for 30-60 minutes before changing oil.
Sea Foam® is very safe and effective in the ways described above. Most people that own and work on Diesel cars and trucks know that no liquids or sprays should be used through the air intake system of a Diesel engine including cleaners and starting fluids. If this is done to a Diesel engine it can cause major engine damage including Hydro-Lock or uncontrolled engine acceleration known as “RUN AWAY”. Do not add Sea Foam® to the air intake of a Diesel engine!!
If these simple instructions are followed, Sea Foam® will effectively and safely clean your fuel system, injectors and the crankcase when used in Diesel engine applications.
