I just mixed up my first big batch of WMO and for use in my 04 CR. I do have a FASS system with a Baldwin filiter that goes down to 1 Micron. I used a 250 gallon farm tank in an enclosed trailer and put in 110 gallons of waste motor oil, filtering through a 10 micron fuel filter then added 20 gallons of gasoline, 10 gallons of cooking oil and the rest #2 diesel. I have run it about 275 miles with no problems other than some more smoke. I am worried about the cooking oil in the cold weather but I hope that the gssoline will help thin it out. I will let you know how the combo works after I get more miles on the mixture.

:yell:I have heard several times NOT to mix cooking oil with WMO.:yell:

It has been known to cause polymerization and clog the fuel lines/filters/injection pump!

That being said, you are living proof that it can be done successfully, but for how long? :dunno

Man, I certainly wish you the best of luck! ;Sweet

I am not saying you are wrong but I am hoping that the amount I poured into a 250 gallon tank is not going to make that much of a difference. I sure hope I dont have any problems since this is my daily driver and work truck. I also have heard that WMO will not work in a 3rd Gen truck either and I know that is not true. I will be putting some miles on it this week and next weekend and if I go through about 500 or more miles of this fuel I will feel a little better. Does anyone know of any solvent that I can use in there that will clear lines while burning off the stuff(WVO), I have a very small percentage in the mixture, about 10 gallons in a 250+ mixture of WMO and #2?

my 2 cents

i've heard to mix ½ ounce each of acetone and xylene per gallon of WMO to thin it & help the fuel atomize and burn properly once it is injected into the combustion chamber. But gasoline (in a different oz per gal ratio) has also been successfully used for this, as posted by other members of the forum(s). The older diesel engines are much more forgiving than the newer ones when it comes to alternative fuels. I think the viscosity and specific gravity are of utmost importance if you are running these non-traditional fuels in a Common Rail Diesel. :yell: You DO NOT want the mixture too thick!:yell:

I use a centrifuge to refine and polish the WMO and then employ a hydrometer to measure and get it as mathematically close as possible to actual #2 diesel fuel. Plus, I live in a warm climate, which certainly helps. If it gets cold where you are, you might experience fuel starvation and/or hard starting when your fuel system cannot move the thickened mixture fast enough when temps are super low. A heated fuel filter would solve that problem though.

I think it is cool that you are experimenting with this. ;Sweet
I just want you to know that there are risks involved. Expensive risks at that. :angel:

33% kero and 66% WMO gets your sg down to the .85 range- thats the general sg of #2 diesel

thats a ruff number cause if you were mixing 50w oil it would take more kero than if you were mixing 5w oil

kero and wmo burns pretty good . i add alittle bit of 2-stroke to the kero befor mixin to help with the keros lack of lube properties--extra precaution

i was one of the guys that experienced the wmo+wvo problems. i try to keep VO as far from dino products as possible. i didnt have any problems untill i had put alot of miles on the blend. had to change the whole fuel system. all of my fuel system had a thin layer of goop on the inside of the filter housing, fuel lines and fuel tank. not much but enough so that after thousands of miles it started starving itself. i think 10 gallons would be fine but i also think the problems with wvo+wmo are cumulative. i bet bi-diesel would help with this though--i didnt try that.....

ummmmmm, you lost me with that 1st sentence. What would be the point of mixing Kero and #2 (unless it's for arctic temps) ??? :dunno

Wouldn't that just be less lubricative than running straight #2?

I am up to about 350 miles on my mixture and the only complaint that I have is the smoke. Even at idle it is fairly bad. I guess I need to add more gasoline. I only put in about 20 gallons into a batch of 275 or so gallons so maybe I should take it up to 20%. Does anyone know the make ratio for use of gasoline? Other than the smoke I am running fine and it is much quieter. EGTs are a little higher but not much I can only assume from the gasoline and the oil in there??

I am over 1000 miles on the mixture but man the smoke is bad. I did order the specific gravity teter and will put it to use but the mix is in the truck and I have to keep rolling with it until it gets here. Any help on reducing the smoke, other than installing a water injection kit?

to reduce the smoke, just put in some plain old #2 diesel. Sounds like you are running way too high a WMO ratio. You might want to thin it down a little in the meantime. You are doing these fuel experiments on a very-expensive-to-repair 3rd Gen. Just so you know, LOL, you would be much better off doing this with an older (and cheaper to repair), mechanically injected unit, like a Mercedes Benz 240-D for instance. Or a P-pumped 1st Gen Dodge CTD. :dunno
I am NOT trying to discourage you, please dont take it the wrong way ;Sweet

i personally dont use water injection, but have heard from plenty of people who do use it and swear by it. If you are running high mix ratios of WMO/fuel, you are going to be introducing more carbon into the combustion chamber, which may or may not form deposits that can degrade power by clogging yada yada yada. Supposedly, water injection steam cleans the combustion chamber to prevent the carbon deposits from causing problems.


Also, working the truck pretty hard will help to burn off carbon deposits from time to time. I would still run a bottle of diesel fuel system cleaner in a tank of plain diesel fuel now and then to keep the injection pump and lines somewhat clear and free flowing.

I only used 110 gallons of WMO in a tank of 275 gallons. I guess I need to poay attention to where I am drawing from in the tank. Maybe that stuff settled and my pump pickup may have been too far on the bottom. I know the 3rd Gen is pricey to fix but I dont mind living on the edge. If I ruin this motor it gives me all the excuse I need to rebuild with a good performance build. Thanks for the info and I will keep you posted.

I have ran wmo 50% with diesel 50% in my 03 dodge 3500 cummins.What I have learned is when it starts smoking too much you have to run 100% diesel with injection cleaner double strength. It takes 1to 3 tanks to clear up. The first time it starts running rough you will have to do this and romp on it every so often to clean out carbon. The first time my 03 ran bad after 3 tanks of mix I thought the injectors were gone. So I ordered tips and went to 100% diesel with cleaner and before tips came in mail the carbon cleared out and no smoke and was running great. So I am running larger tips now. I would say after run 20000 miles cleaning up every 2 to 3 tanks is the only way to go in
a cr running wmo mix .I do have rail ,boost,lift pump,egt gauges
also water injection,and inline fuel heater and inline 2 micron filter
just after my fass liftpump. I have used up to 10 % gas by volume but allways end up smoking after so long and dont
use gass in hot weater pulling.

Thanks for the info and I will cut the mixture back and run some cleaner through there. Any recommendation on what cleaner works best? I plan on making some trips soon that can run this stuff through the lines.

I use power service injector cleaner. Also ordered a case of vegie powers injection cleaner both seam to work about the same. My truck smokes more on first tank at 100% diesel. Sometimes it clears up in one tank then sometimes 3 or 4 to clear up . I realy step on the accelorator hard every so often out of town and blow black untill truck is ready then all clears up.First few times seamed like it is going to never stop smokeing
but it hase every time. Some times it runs with slight miss before it clears out. The water injection and fuel heater helps but not 100% cure.
