Burning your used motor oil with your fuel

[Trent]

I've searched the Cummins site and I don't think its there. The only 5% anything I've seen is the 5% maximum biodiesel blend.

Lets see Piers injector pump $3,500 EDM injectors $1,500 complete engine 15,-20,000 and I could save money? For how long and with who's guarantee. Not cost effective with the cost of engines these days. I do have dual filters and extend my filter changes and have never had a bad oil analysis.

With the guarantee of Cummins supposedly. Am I the only person who thinks that this is misinformation?

Look, I simply posted why *I* did it. I'm not trying to convince anyone to do it. If you don't want to burn oil in your truck, then don't--it's pretty simple.



1dslram, I would agree with you--as I wrote earlier in this thread, if you do this to save money you simply won't come out ahead.

Military Burning Used Motor Oil

I found this on Google



Cost-conscious maintenance managers are constantly seeking ways to do business with less money, fewer people, and minimal changes to the workload or workspace. Oil and fuel blending is one process that meets all of these criteria and is mechanic friendly.



Fuel blending may be performed when directed by the Army Oil Analysis Program laboratory or during any unscheduled maintenance when an oil change is required. Waste motor oil from a vehicle's crankcase is blended with diesel fuel or JP8 fuel from the vehicle's fuel tank. After passing through a filter, the oil and fuel mixture is put into the vehicle's fuel tank to be burned as fuel. Fuel blending should not be performed if the oil has any sign of antifreeze contamination.



The oil and fuel blending system consists of a drain pan for collecting the waste oil and a pump and blender with hoses. The blending device (see photo below) draws oil from the drain pan and fuel from the vehicle fuel tank, blends and filters the mixture, and returns the blend to the vehicle fuel tank. The filter removes virtually all contaminants that could potentially damage engine components except antifreeze.



The advantages of using the system are many—



• Any traditional diesel engine, such as a vehicle or generator, can use the system.



• The blending process takes only an average of 15 minutes.



• The cost of one gallon of diesel fuel is saved for each gallon of waste oil blended.



• The cost and labor involved in collecting, storing, and transporting waste oil is nearly eliminated.



• The blend is consumed with no adverse effects on the engine or any unusual emissions into the atmosphere.



• Reusing the oil prevents most oil spills and the resulting cleanup costs.



• The process is an environmentally friendly method of disposing of used oil.





For 33 vehicles using the oil blending process over a 3-month period during Operation Joint Forge in 2002—



• The blending operation required 12. 25 hours as opposed to 49. 5 hours for a traditional oil and filter change, saving 37. 25 hours, or $745.



• Mechanics blended 70. 5 gallons of oil, so 70. 5 gallons of fuel did not have to be purchased.



• No storage, record keeping, or $50 disposal fee were required for 70. 5 gallons of waste oil.



Oil blending has many advantages and few disadvantages. Probably the most significant reasons for using this process are that it eliminates fuel waste and helps keep the environment clean. The system is approved by the Tank-automotive and Armaments Command and should be required in all maintenance activities. ALOG

Interesting. If I read that correctly it appears the unit mixes waste oil from a drain pan after draining with the vehicles fuel and then back to the tank.



Thats about a 12% mix if they are returning 12 quarts back to a mostly full tank. Anyone know what piece of equipment that is?

 

[Midnite]

That's very interesting. I'm sure at the scale they're doing it there probably is some savings to be had. A 12% mix is quite a bit of oil. It doesn't take much oil to raise the lubricity of #1 diesel significantly, so that's why I stick with just a couple quarts per 35 gallon tank.

Thanks guys, the Gap isn't too far from here and I know some people, If I find anything out from your leads I will be sure to post it.

by the way, today one of our mechanics overfilled an engine by about 3 gallons. I had him drain it into a clean bucket and then I strained it into 2 2-1/2 gallon jugs using coffee filters, (this took all freaking day!!!) and then dumped it into my fuel tank just prior to fueling up. I can say that I have not noticed any difference in anything. Truck runs like normal, however I still have some hesitation about running "real" used oil in my fuel. But I do feel a little more confident having tried semi or mostly fresh oil in my fuel.

 

[John Robinson]

It is absoutley not worth the risk!!!, Yea the old guys might have gotten by with it back in `89, But they werent running 20,000 lbs of fuel psi either. They were running about 1,500.

thats why i pointed out that most if not all those doing this have the 12 Valve Mechanical engines, not so sure the sensors in the newer engines will agree with used oil in the tank. . might give them heartburn or worse in the pump.

I dont think something like this would be too hard to make up yourself.

Get a Frantz filter and a restricting (needle?) valve. Plumb it into your fuel return instead of the oil pan, and youre done.

Hummm... . I already have a Frantz... ...

Eric

How about adding a needle valve after the Frantz oil filter that would allow tapping off some of the clean oil into a container.



A person could tap off a couple quarts of used oil (cleaned by the frantz) to be added to the fuel tank say, every time they change the paper-roll. Would be neat if you could eliminate the need for doing periodic oil changes.

My ex father in law was a reserch chemist for the Bureau of Mines. In the late 80,s the Air Force contracted for a study on reusing waste motor oil in fuel. They found that a 10% mix worked fine with no problems at all... ... ...

Interesting. .



I've dumped up to a gallon of oil at a time in the 66 gal extra tank, and trickled that into the main tank. Never could tell a difference in how the truck ran. Not aware of any problems caused (yet), but probably should think about the possibility of carbon deposits on exhaust valve stems. Kinda like extended idling. .
