I see a lot of people saying that they filter their waste motor oil and run it in the tank, but what do you use to filter it?

What raito do you run?

TIA!


mad

Wishing to know as well.
Can we get a parts list too?

I know you filter it outside of the truck, then pour it in the tank, then goes through more filtering, then the fuel filter, then the pump. Right?

Yeah. I'm sure that I could set up a 10 micron or so... but I don't think that I need that much. Just take the chunks out from the dirty pan that I drain the oil in...

You can buy 1 micron bag filters off of ebay. That's what I would use.

2 gallons is safe. I wouldn't go over 4-5 gallons though.

Thanks, Dude!

I have run as much as 7 gallons of WMO in my 20 gallon tank without problems. Others have run up to 100%. I am happy at 33%, but may try 50% soon. I'll keep going if it isn't a problem.

Filter with a centrifuge and stack my fuel [ as cost & availability changes , biodiesel - some WMO or hydrolic ect for BTUs , #2 , additives ] .
Then a lot depends on what fuel / motor you have , as the manufactures evolve the systems , they lend themselves to fewer alternative fuel sources .
So this would be a good point to boycott , only buy older used [ P-pumped 12v or 24v engines ] .

I bought a 2 micron spin on filter and a hand pump. I ran the waste oil at 50% in my GMC. I have not dared to run it in the Dodge yet(VP44's cost to much).

excellent info, Mikey! that is what i am currently using for filtration, works great and very cost effective too![coffee]

I've not yet tried any higher % than 2½ gallons per tank yet in my Common Rail. In the near future...I probably will, although i worry about excessive ash & carbon formation in the engine/exhaust as a result.[director]

I've run a 50/50 mix for a while without any problems, that includes towing. I do have a 2 micron filter added to my truck.

DD,
Have any pics of your setup? I'm thinking of doing the same.

MikeyB

IM filtering with 5 micron bags, and a 50-50% mix,97 GMC 6.5T, 5000 miles no probs, sure saves a lot of money per yr. gonna start to go to 75% WVO and blend with kero, and 6oz. diesel kleen, 3oz.acetone to 10gallons, much less money, I guess its always about the money!! thx Ron

next on the 97 GMC will be a water injection spray to steam clean the chambers, once a week so no carbon-coke buildup. turn on the spray for 1 min. at hiway speed when engine is up to temp should do the trick!! Thx Ron

DD,

no, but I suppose i could take some! You (and others) may find this hard to believe.... but i've never posted a picture on this or any other forum. Always wanted to learn, never took the time to do so. Is it difficult? Do I have to open an acct on some hosting site or something?

DD,
You can load the pics here on the DTR site or using a hosting site like Photobucket. Not really hard to do, just follow the upload steps.

If you use the DTR the maximum picture file size is 500KB. So you probably have to resize.


My Dad has 3 barrels of WMO sitting at his shop waiting to be disposed of.

Trying to decide on the 1 or .5 micron bags for filtering.

MikeyB

I use a tuthill 115v 18QPM pump from yant equip & push through a 2 micron Baldwin bf1212 filter that also separates the water. Not the cheapest set up but works well.

DD, if you would like, PM me and I'll talk you through the picture thing...

I made my first batch (2 gallons) yesterday. Lord it took forever to filter through the coffee filters.
So I ordered the 1 micron polypropylene bag filters off of ebay today. Will pickup some 5 gallon paint pails for the filtered oil at Home Depot.

I will, just been having computer issues around here for weeks now, caught some stinking virus on my desktop which rendered it insignificant for the rest of time![verymad]

so i'm on my ancient Dell laptop which is slower than a 1980's GM 6.2 liter diesel Blazer towing a heavy trailer up a hill. With a headwind.

My pictures and stuff are all on my other computer, and my sister is supposed to come over and help reformat it and try to save some of the pics too. Hopefully this will happen soon and then i'll post some pics of my truck and my WMO filtering setup and my dog and anything else anybody wants to see[laugh]

i'm looking for a 6.2 [laugh]

i thought i read in a couple different places that the used motor oil is not good for the common rail, but is just fine in the 12v and 24v... i could be wrong though it has happend before. [laugh]

Don't think it's a problem if the WMO is filtered really good. Like with .5 or 1 micron filters. And to think that the Fleetguard fuel filter for our trucks is only a 7 micron. [coffee]

And a low dosage of around 5-10%. About 2 gallons per tank.

Rambunctious - I've been running (waste motor oil = WMO) in my own CR for a while now, about 2 gallons per full fuel tank. I filter it down to 1 micron and de-water it as well. I have 5 micron filtration on my truck. It honestly quieted down some of the "clacking" noise from under the hood. I can hear the difference standing in front of the truck with the hood open and the engine idling. Since motor oil has more BTU's in it than actual diesel fuel, the truck runs GREAT on it. In theory, the lubricity of the oil/fuel blend would have to be better than the current ULSD is for injection pumps. My only concern with higher concentrations of WMO/fuel in a CR would be coking of the injector's tips (which i've only heard about and have no real world knowledge of). I know for a fact that you can run very high concentrations of WMO in the old 12 valve trucks with absolutely no issues!

2 gallons of WMO added to your fuel tank will currently save you 10 dollars at each fill up. Not very much money when you consider the risk you are taking with your injection pump and system. Most people are unwilling to risk it.

[director] IMHO, with the ever escalating price of diesel fuel, I am all for anything that helps me further along this battle. Let's face it, these trucks are NOT economical to drive. If you can stretch your fuel supplies by adding a few gallons of WMO to your full tank of #2, it will add up to a few hundred bucks by the end of the year. More than a few hundred if the prices keep going up. And depending on how much you drive of course.

If you (like me) get an average of 16 miles per gallon combined city/hwy, and you add 2 gallons of WMO per tank, you are getting 32 free miles of driving on each tank. If you tank up about every other week (26 X a year) thats 832 miles of "free driving" that you are getting out of WMO at the end of an "average" year. Depending upon how much or little you drive, you can maybe see where I am going with this. [coffee] :cool:

Adding to DD's statement motor oil has about 20k BTU's per gallon more than ULSD.

I use a Harbor Freight 1" clearwater pump to push the WMO (and ATF, etc.) through a pair of filter heads with a 5 micron (first filter) and 2 micron (second filter) spin-on cartridges. Depending on temp and the viscosity of the oil being filtered, it can be a little slow. I dropped to 3 gallons/minute this last winter.
I've run 80% ATF/WMO mixed with 20% biodiesel. The truck didn't care, but it smells. And it smokes more on aggressive launches, too.
It's cheap, and it works. I likee.

that sounds like an efficient set up you have there. I do hope that you are sending the oil on several passes thru the filtration before you pour it in the fuel tank. It's weird how filters will catch more junk out of the fuel in multiple passes. I filter mine at least 3 times, but i do it by hand. If you have an electric pump, you can just let it circulate thru the filtration system for an hour or so and let it really polish the oil into a purer form of fuel for your truck.

a coffee filter is 7 micron ???

The Fleetguard fuel filter for the CR is 7 microns. Don't know what's the rating for a coffee filter is.

BTW, I'm running the 5 micron Baldwin filter in my truck.

I was just testing with a coffee filter. That oil is going to be refiltered once my 1 micron bag filters arrive.

Zactly. I run the "outflow" back into the tank and let it run like that for at least 2 hours. The pickup is in the bottom center of the barrel and the return line is set to create a vortex, or whirlpool, to make sure every gallon makes several trips through the filter.

Whole thing cost me about $65.00. I've run over 450 gallons through it. Niiice.

where are ya'll running across that much WMO?? seems like a pain for me to do this once every 5k miles when i change the oil

I have a commercial auto repair business. I have plenty of WMO.

I have a LOT of friends and neighbors who tend to show up at my door when having auto issues or want to do some maintenance on their cars but dont have all the tools, axle stands, drain pans, Nascar jacks, etc, that are in my garage LOL [guitar] lucky me[laugh]. But over some time and experience, I have got oil changes down to a 12 minute procedure nowadays on almost any vehicle except for a modern corvette (those are a royal pain unless you have a lift). Between all of these people and their girlfriends and parents and siblings, i have plenty of WMO at any given time.:cool: Plus I get to keep all the extra ½ quarts and stuff from cars that only take 4½ quarts to fill them. If you start putting the word out that you change peoples oil, they'll pay you to do it and sometimes even bring dinner and/or beer (a big plus for me - i'm a bachelor) When you think about it, you are a getting a constant supply of alternative fuel that way. For free, just takes a little bit of your time. If people are going to be "donating" their WMO to your cause, try to steer them towards dino oils rather than synthetic oils, which tend to smoke more and not run as well when used as a fuel in diesel engines from what i've heard.

I may have occaisonally unknowingly ran some synthetic oil through, but i try to make an effort to know the source of the oil if i'm going to be running it through my engine. So far, so good.

YMMV.

Our oil comes from friends and family.

I'm going to do a test this evening with synthetic oil to see how well it burns since we also have a mix of dino and synthetic. I think it will be ok as long it's mixed together.

BTW, the 1 micron bag filters arrived, that is some thick material!

MikeyB

Mikey in my experence synth is a mistake that you will regret since it tends to turn to a goo that will plug the filter & cause fuel starvation & to top it off you will have to find some way to drain the tank also.

Hmmm. I'll check for that. I have some fresh synthetic oil that I can mix with diesel in a beaker.

MikeyB

You know, thats sounds like another "synthetic myth" Diesel engines have fuel blow-by just like any other engine. I work at a truck shop maintaining a fleet of trucks, and we run full synthetic in everything. Ive never seen any sludge in these motors.

But, I would still do testing first. Im thinking of running WMO in my truck, as I trow away probably 20-30 gallons a week, but it is synthetic oil. Ill have to get some from the next change and see what happens when I mix it with diesel 50/50.

Im working in my head on what I would need to build to run a gravity feed system, that could do 5 gallons at a time. The simpler, the better. Ill post pics one I get it all figured out.

Here is what I came up with.

http://i291.photobucket.com/albums/ll308/TurboshadowWA/WMOfilter.jpg

5 gallon buckets and all gravity feed. I'm hoping I can get it to siphon through the 10in filter. If not, I may have to do something different. Everything IMO could be picked up at a local hardware store expect for the filter. Here is the link for what I want to use.

What do you guys think?

I did a test between synthetic vs. conventional motor oil. I soaked paper towels in Castrol GTX and Mobil 1. They both burned about the same rate.

And Mobil 1 seems to disperse very well in diesel fuel, just like conventional motor oils.

MikeyB

Oh well you will learn. After I tried to run some blended synth in my old ferd IDI & goo'd up three filters in less than 100 miles I decided that was enough non dino oil for me. BTW the synth willburn quite well when hit with a flame it just does not like to pass thru the filter on the truck, which is what will shut you down.

Oh well you will learn.

Which oil where you running? I don't think Mobil 1 is a pure synthetic like Redline, Royal Purple and Amsoil.

MikeyB, I'm interested to hear about your findings with synthetic oil. I think a quart or two snuck in every now and then wont make much of a difference.... But maybe that is my bold optimism showing![duhhh][laugh]

all i know is, for about 20 bucks in materials and a few hours time, i have a constant supply of an alternative fuel source (WMO) that my engine seems to love.[coffee]

hahaha i do that too ![laugh]

I can only report on the Mobil 1. But it did blend with the diesel fuel very easily.
For the first 2 gallons I did a 50/50 mix of Mobil 1 (used) and Delo 400 (used). Nothing unusual during the filtering and polishing. Also have 16oz of Power Service Diesel Klean mixed in. I haven't noticed any difference in how the engine sounds or runs with the mix.

DD,
How many passed will the 1 micron filter last?

I bought a barrel pump and a spin on filter adapter. I screwed the spin on filter adapter to the barrel pump and a hose on to the spin on filter adapter.
The waste oil goes in the barrel and I pump it from the barrel through the filter and into the truck.

Badme,
It's a good idea to run the cleaned oil through the filter one or two more times. That process is called polishing. Multiple passes through the filter will get the oil much cleaner than with just one single pass.

i've put probably 20 gallons thru it on multiple passes, it flows a bit slower now, but still doesnt need to be changed yet.

Good to know. My 7.3L buddies are dying to start doing the filtering and asking about the filter life.

MikeyB

which 7.3's do they own? The later powerstrokes, or the earlier version naturally aspirated IDI motor? The older ones can run upwards of 50/50 WMO with no issues.[coffee]

The later Powerstrokes, '99.5-02 SD models.

MikeyB

DD in warm weather the old IDI's will run on 100% WMO but won't start that rich when cold much to my dismay but they will readily start on 70/30 in warm weather & 50/50 in temps down to 20*.

I've been thinking about this whole synthetic wont work thing, and I just don't see it being true. But, what I do see being true, is that it has alot more detergent in it then dino oil. One of the large differences between syn and dino is the additives. So if syn gets better additives and has more detergents so, maybe it isn't the syn oil clogging the filters. But all the crap in your tank and lines kicking loose and clogging the filter and doing it alot faster then dino oil.

Kinda how putting alky fuel in a gas car will clog up everything real quick.

thoughts?

TurboShadow,

I'm thinking the same. The detergents is cleaning the gunk in the tank and plugging the filter. It's like running biodiesel for the first time in an older diesel and clogging up the filter with junk. Takes a few tanks to clean everything up.

MikeyB

hello this is my first post. i like what i have read about wmo. i use it at 100% in my 97 dodge. save $500 in the last few weeks i love it. this is what i do. filter it at 10microns then through a house water filter at 1micron. using a harbor freight pump i let it run for hours around and around through the 1micron filter doing 55 gal at once. i add 10 oz of acetone per 10 gal. at $14 a gal. add 1 gal of mineral spirits to a tank [33gal] at $12 per gal. then a whole 60oz of diesel kleen to the tank [33gal], sometimes less diesel kleen. i get no smoke, better mpg, sounds quieter and feels like more power. the oil i run has everything in it from 90 weight, atf, wmo, synthetic and fryer grease out of the fryer through a filter into the 55 gal drum[smells better] there are a lot of nay sayers out there. but you guys are great. i have read a lot ,talked to petrolum enginers, talked to old boys that have been doing it for years. works in skidstears, backhoes, forklifts, but they are old stuff. acetone, paint theinner, and diesel kleen make it all work togeather. I put it a coke bottle in my wife freezer and took it down to -7 it looks like i will be able to run it in the cold I aint going back with out a fight. what at $1.50 a gal.???

Has anyone done an oil analysis, on the engine oil(not the oil used for fuel) to see if combustion blowbuy with used motor oil fuel is contaminating the oil?

Has anyone done an oil analysis, on the engine oil(not the oil used for fuel) to see if combustion blowbuy with used motor oil fuel is contaminating the oil?

Yes I have , but the results do not make sense , I use only about 6-8 gals. , 3-4 times , running about 10-20% WMO to 80-90% #2 .
And this is WMO that went through a dual by pass filter system into a bulk storage , 55 gal. drum , then 4-6 hrs. through a centrifuge , then into tank .

Some how the 1st posting was just the wrong file , the 2nd some how is a over size scan of the report , do not know how to reduce , it will not load as is .
If you need some questions answered , let me know .

The PDF you posted is not of your oil report.

John at the $ amounts that I save I could care less if I only got 3 years out of the motor since its paid back in far less time after that its all gravy, at just 50% which was my wiinter blend in my ferd IDI. At just 40k miles I save $3,500 which is way more than an IP & nozzels cost plus I'm sure that I can also include a preformance rebuild for not much more. At 75% the savings are over $6,000 , so pick your blend ratio higher more savings & less life on the pump & nozzels - lower for a longer pay back. Your choice.

I am mostly looking to see if the wear metals are high. This would be mostly iron , lead, copper. I do regular oil analysis on mine, and have run about 20 gallons so far about 10% mix. However my last oil sample showed greatly higher lead, and iron was a bit higher. So I am thinking that wmo may be raising it. I have changed the oil and not burned any wmo, resampled and it shows normal, except slighty higher lead, but noware near the previous level. If the truck was high milage and falling apart I would not be to concerned, however with low milage, and hoping to keep it for many years I don't want to trash it. If I can run wmo and not harm it then great, sure could use the savings.

What I'm saying is if the savings are high enough then I don't care how much wear since the savings more than pay for any repairs. And according to my experience they most definitely do by far.
