Does anyone have any pics or info on a decent home made set-up for filtering used motor oil? I would like to be able to maybe use a spin on filter. I was thinking of using a reservoir to pour oil into and then want to filter it through and into another reservoir. But, I don't know how to get it "pumped" from one tank to another easily. Even some form of gravity feed would work, I'm in no rush...

I would just appreciate some ideas...thanks

I'm using 1 and .5 micron hanging bag filters with a capacity of 1.5 gallons. I hang the bag over a clean 5 gallon container and pour the oil into the bag and let gravity do the rest. I filter the oil 3 times through the 1 micron and then the .5 micron for the final filtration.
Pretty simple setup but effective.

The bags can be found reasonably priced on ebay.

I have a set up for filtering used oil. Works ok. Ill try to get some links/picts together.
I use this for a filter(replacement cartridge from any auto parts store):

There is also a pump on that website that I use.
Picked up some tubing/fittings from lowes. I pump the filtered oil in to a 55g drum for storage.
When I change the oil in the dodge, I strain it thru a paint strainer that fits over a 5 gallon bucket to get out gravel/debris. the filter it with pump.
I just got a farming magazine that has two articles on filtering waste oil for use in diesel. i'll try to find the name of magazine.
I really havent gotten in to a habit of mass producing it yet. "One of these days" projects I guess.

How many uses do you get out of each bag? Or how many gallons do you get from each bag? I was looking at these to filter WVO to make biodiesel.

If you're looking to make biodiesel, don't bother filtering it. Run it through a screen collander to get out the beaks, claws, and big crumbs. The rest will settle out with the glycerine, and the tiny amount remaining can be filtered out with a 2 mic. spin-on filter when pumping it out into your truck. Or through a 1 mic. bag filter when you dump it into your "finished fuel" tank.

I'm guessing around 30-50 gallons per bag using WMO. Final filtering for biodiesel I don't know, but guessing at least a few hundred gallons.

Thanks guys!

Thanks for the replies. I was looking into those bags and was also wondering how much use you could get out of them.
Right now that'll work for what I need. Hopefully in the future I will need more if the bio-diesel plans ever get to come together...

Ok we'll do this again 4 years plus of experimenting have resulted in this. A tuthill waste oil pump 50 psi 18 qpm 115v thru a baldwin BF 1212 filter 2 micron rating with water seperator let circulate in barrel on timer 30 min duty cycle for 6-8 hours then add to tank in your desired ratio turn key & go.

Sounds like an effective set-up for sure! I'm just curious here, but what is the purpose of the 30 minute duty cycle?

Pumps live a lot longer if they don't get too hot & I've got the time.

I have an old dual by pass filter system [ down to 2 micron ] ran 35 gals in a 55 gals barrel through this for about 15-20 hrs , then used my Diesel Craft centrifuge [ down to 1/10th micron ] for about 20 min. [ would have gone longer , but I had just set this up and it needed a couple adjustments ] , by then it had accumulated about a 1/16" of soot in the bowel , they recomend running oil through till it cycles through about 3-4 times [ that should take about 120 min.s ] so I now know that it works much better .

John,
Which unit are you running?

This is not mounted on the truck , from what I understand , the oil system in the 5.9 will not work with these .
I use the OC-20 as a stationary unit for cleaning waste petro oils & in the processing of waste vegi oil for bio diesel .

That's the unit (OC-20) I'm looking at. Appears the motor/pump assembly from Grainger #6PA30 would make a good setup.

MikeyB,
Any idea on the price for that OC20? I see they have the universal kits but found no prices.

I found a couple of biodiesel supply shops on the internet that has the OC20 for around $299.

Thanks.
You plan on using this for WMO to run in your truck?

I'm thinking about it. Not right away but in the near future if I keep running WMO.

I do not know the spec.s of either off hand , but 80 psi , at .93 gpm or 55 gph ,
at 170*F , is what they say the pump should be fed .
Graingers may say that a 1/3 hp motor at 1725 rpm , is ok , but I think that a 1/2 should be used and watch the rpms , a pump that is rated for the OC20 should run at 1725 , not all motors are at that rpm .

Those centrifugal filters arent cheap.. especially considering whats inside them.
But theyre the best way to get the soot out of the oil since they filter to sub-micron particle size.
You could filter, but youd need a lot of energy or time to process it.
the extra long bags work great when hung over a funnel / barrel overnight.
you can stack bags inside each other if that helps.
When I filter I just go down to 10micron since im lazy. Ideally I should invest in a 2micron element. I just pass the fuel through a racor 500FG on the way to the tank.

Centrifuges are the cheapest way to get the cleanest fuel or oil , never buying a filter again adds up quick , having sub-micron clean fuel or oil has value , it does not take much to do it , pour it in - turn it on , use the same pump to fill what ever you want to fill .

I have a 1999 Dodge with 168,000 miles on it. I don't use it much, only a couple of times a month to go to my hunting camp. I wanted to try wmo, not only to save $, but because I want to send some people the least amount of money I have to. To make sure it was filtered enough, I filter through a mercury outboard water separator/filter, then through a Goldenrod 15 micron water separator, then though a 10 micron Fram, then through a 2 micron Wix 33528 (same and interchangeable with a Fleetguard FF5320). It comes out looking like dark diesel. I do 5 gallons at a time and use one for each time I fill up. It filters by gravity, but if you are in a hurry, install a tire air valve in the supply tank and put in around 20 pounds of pressure and it will fly through. So far I can't tell the difference with running 100% diesel. Tractor Supply is a good place to find remote filter bases and filters. I found the 2 micron at a local auto supply. Everything cost a little over a $100 which payed for itself with 4-5 tank fills since the wmo is free. From what I know, the 99 Cummins is a low pressure fuel injection system. If anyone knows if this might work as well in a CDI high pressure system, I would like to know.

Fred,
I'm testing WMO in my common rail. But at only 2 gallons per tank right now. Using 0.5 micron bag filters for the final filtration.
