Is there a place to go that has some real good info on using WMO without all of the input from the people that are against it? Every thread here starts out great and then get's into some guy interjecting why it is a bad idea, or veggie is better, or bio is the way to go.

I just want good information on WMO. It seems to me the quickest and easiest way to go.

 

Just like any alternative fuel, WMO has its issues. As pure burning fuel, it's been used for years for items like ship fuels (aka heavy fuels), etc. But to use it as a fuel source for a diesel engine requires a fair amount of prep work to the WMO. At it's core, WMO is just refined oil and you can generally treat it like SVO for burning it. But it's the particulate debris that is the issue. Primary large particulates can be filtered out, but it gets more difficult to remove the really small stuff like metal particulates. A popular method has been centrifuging the oil to force all the particulate debris to the "bottom", and there are plans on the web for building your own. But like all the alternative fuels we talk about here, you just have to figure in the tradeoffs, like the amount of time and effort needed to clean the WMO to use it safely (or the amount of time to put in an SVO system, or the amount of time and equipment needed to convert WVO to bioD.)

Everyone has their favorite method, and all of them have their issues that you need to address. If you want to use WMO, go for it. I'd search online for topics like WMO filtering, centrifuging, etc.

Sourcing it can be an issue as well, just like the growing competition for WVO. The biggest sources of WMO are lube shops and the like, and many of them have contracts. And remember you'll need gallons of the stuff.

Good luck!

I understand you want to get information about using WMO as fuel for a diesel engine.
Despite the apparent cost benefits of using WMO for fuel you cannot ignore the chemistry and physics involved.

Motor oil must be able to maintain a lubricating film between two objects that are rubbing together, to do that it must have high viscosity.
Fuel oil must be able to spray thru a tiny aperture and break up into extremely small droplets, to do that it must have low viscosity.

Motor oil must have a high enough flash point to avoid being burned at combustion chamber temperatures.
Fuel oil must have a low enough flash point to burn readily at combustion chamber temperatures. It must also burn quickly enough to ensure almost complete consumption of the injected fuel volume during a combustion event.

Motor oil is designed to pick up, hold, and carry off the wear products (often sub micron sized metallic particles) and combustion by products that tend to accumulate in an operating engine.
Fuel oil should be free of contaminants to avoid blocking small passageways and damaging delicate metal fuel distribution system components.

Even if you can totally eliminate the contaminants from WMO, an almost insurmountable task, you cannot change the other two because they are physical properties of the oil.

Quick and easy yes.
A practical solution no.

If you want an honest discussion you must be willing to accept the negative input along with the positive input you desire.

 

Couldn't help yourself, could ya?!!

 

Just offered you for free what I would normally get paid for.
How you use it is your choice.

 

And some people only hear what they want to hear....................Wow, 3 posts in 8 years...............

 

When you see some one jumping out of an airplane with out a parachute you need to speak up. We know that some people have lived with out the parachute but it’s rare.

That’s all I am hearing here on this form…… Dude where your parachute? Good luck on your jump!

 

Gentlemen,

The problem here is that many people want to run 100% wmo. If you run a reasonable mix of pump diesel and wmo, there is no problem. Cummins used to authorize up to 15% wmo in their engines. I would think 50% wmo and diesel would run very well with no issues.

Ken,
The issue with waste motor oil is the very fine metal and other contaminates in it. The new Diesel engines are running very high injector pressure for a very fine spray and the metal and other crap in the WMO will cause erosion to the injectors and cause poor engine performance. That’s why Cummings use to say 15% WMO was ok. If you could remove all the crap from the WMO it would be ok to run it in a new Diesel engine.
