Burning crankcase oil?

[R.E. Miller]

I would not recommend doing this to ISB or ISC diesels due to the nature of their injection systems. The rotors in their pumps are very sensitive and operate with very, very fine tolerances. Other then that, I don't think that the Centinel system meets California emissions, so that might be an issue.

So what would be the pros and cons of adding new non-used motor oil within the specs Cummins recommends?

Regular motor oil isn't designed to be burned and leaves ash deposits. Some folks use 2 cycle engine oil which is designed to be burned but it costs more than a designed for diesel fuel additive.

I would be very concerned about dissolved solids, ash, heavy metals and other contaminants that will go through your injection system, as well as get cooked out, coating your injector tips, pistons and valves. It's just not worth it to me.



Make an oil burning provision for your wood stove or experiment burning it in your oil furnace - about all you can do there is plug up a filter, nozzel or ruin a relatively cheap pump.



Or, if you have an old 6. 2 or 6. 5 GM diesel, burn it in that. But don't risk hurting a good engine for a few dollars savings a year. If you need to get rid of it, spray it on the bottom of your truck to prevent rust.

I recycle my used oil whenever I need to fire up a pile of brush. Someone gave me a drum of kerosene so I mix it 50/50 with the oil. Trouble is, I don't do enough burning to eliminate all my oil. I think if I ever get a nice shop set up it would be nice to have a waste oil heater.



The trouble with used oil is getting rid of it correctly. I don't know if this is true or not but I heard a horror story about used oil. Supposedly, someone's tank leaked and caused some problem's then the company went under so the EPA or the government of whomever went after the various sources of the used oil. I do know of one place that collects requires your name and address.



Scary huh? But then you don't want to do like "we" used to do in construction, that is dump it over the bank out back.

I take my used oil to the local school district bus shop where they dump my 55 gallons drum into their waste oil heater tank with a forklift. Have heard that Jiffy-Lube type places will also take it. Don't ever put it in the trash. My neighbor tried that, when the trash truck compacted it his containers burst open and the truck left a trail of oil right back to his house. The waste disposal company traced it to him and charged to dispose of all the oil contaminated trash as hazardous waste and to clean out the truck. Ended up costing him close to a thousand dollars.

Those of you who do mix some of your waste oil into your fuel, I wouldn't recommend doing it in cold weather or if you plan to run a lot of short trips on that tank. You'd be more likely to create excessive deposits and gum up the cylinders & rings.



I've burned several gallons of oil in my rig, but never when the weather is under 70 F.

They also do this in the Oil Field. Some of the larger crew boats that run the 1150 cu in I-6 Cummins ( six in a boat ) have a system that injects the used oil into the fuel system for the engines to burn. Same thing, saves money and time at the dock.
