Do you have any pictures or manufacturer numbers?

I found pre filter arrangement only in old style manuals or in semi applications using huge filter arrangements suitable only for huge fuel flows. Most of them I found have a filter thread mount of 1" or bigger.

Maybe you have something in a usable common small size?

 

I forget the specific part number, but some of the filter cartridges using the Fuelpro 382 filter assembly are rated in the 30 to 50 micron range. I've seen these on large farm tractors and over the road semi trucks, probably be hard to package in a smaller application.

 

That's exactly the point. I would love to go with a pre-filter, but havn't one yet fitting into the engine bay.

 

As stated, applications using those cartridges also have a secondary filter that's much finer to protect the pump and injectors.

That's why it's filtered before it goes into the vehicle.

The wvo and wmo, that is.

 

After this post I realized I'm further bringing my own self down by even responding, since you clearly know very little about what you're talking about.

I know what a micron is, cause that's what my WVO gets filtered to, below what you are filtering. I filter to one micron, and am looking to go further, so yes I know what it is. That's one micron ABSOLUTE for the record. Centrifuging should put be down below 1/2 a micron absolute.

The broom stands up in WVO because of the viscosity. It has nothing to do with what is in there, that is absurd to even think that. Your own example could be demolished by using a dumpster of clean oil next to a dumpster of dirty oil, but do it in freezing temps. The broom will probably stand up about the same. I can't imagine a broom standing up in WVO anyways, and if the oil is that bad I wont use it, nor will I eat at that restaurant again.

Your example of WMO... try doing that with gear oil. It's just the viscosity, not the particles inside of it. Obviously a thicker oil will cause the broom to fall slower. I'm not sure what that has to do with your original comment of "dirt" being in it. Just further proves your lack of knowledge on the subject.

You're done trying to explain this, because you can not. You are talking above your comprehension now. What stock fuel filters are 20 or 30 microns? Last I knew my stock filter setup went from a 10 micron to a 2 micron absolute. Where did I say I use 4 or 5 filters to filter my oil? WTF? My filtration system has a 200 micron barrel lid the oil goes in, just to keep out those "chunks" then it gets heat/settled as anyone should do EVEN WITH WMO, then passes through a 5/1 micron absolute bag. Just one bag filter.... Then on to the truck it goes. Of course there is a filter on the system on the truck, but that's more of a safety net than anything, all the real filtering is done in the heating and settling process.

Do you know how tiny the orifices are inside of a powerstroke injector? I do. I've done my homework and my system is working. I've had to replace exactly ZERO parts of my factory truck due to an issue with my WVO system.

I hope your track record is as good with the way you like to point fingers. If you want to knock someone else's setup, at least get some facts to do so.

I'm done with this thread, if anyone wants to have a discussion about WVO, you know where to get in touch with me.

 

Just as an reminder:

2 micron is the technical limit to measure particle size. Any filtration in this size must be done by a centrifugal filter to be effective as Mdub already mentioned.

Just to give you an idea about the size: bacteria like the dangerous cholera bacteria are in the 0.2 to 5 micron size.

 

Call these people and ask them to help you with their "Bio-Tek line. You're going to have to decide on length, diameter and the thread diameter.

The ultimate filter is THIS centrifuge, which will take care of any particulates ANS water.............. WVO Designs - Engineering Waste Oil Solutions

And don't listen to all these naysayers because they've never ran any oil and you're not gonna get anything positive out of them.

BOTTOM LINE:
1. Filter your used oil to 2 microns, before it goes into your truck's fuel tank and AGAIN at the engine - using an aftermarket screw-on filter.
2. Make every effort to get only clean oil from a known source that's free from water and antifreeze.
3. Make up a draw tube from 1" PVC, so it draws 3" off the bottom of their tank or drums AND FILTER IT TO 10 MICRONS WHEN YOU'RE PUMPING!!
4th and probably most important - you HAVE to have an Airdog , Raptor, or FASS transfer pump on your truck to pump the thicker oil.
5. I also use a quart of Lucas injector cleaner in every 75 gallon tank I run. Look around - you can find it for about $8.50 if you look hard enough. It's good, cheap insurance.

All else is totally BS. 540 gallons and going strong!!!

 

A while back I saw a post saying a wvo system could be built for about $450. anyone remember this. I want to setup a system for year round use but need a place to source the parts.

 

I can't imagine building a quality system for that price. Even if you built most of it yourself. The tank alone is going to cost a bit to fab up (needs to be aluminum and needs to be heated) the pump alone is going to be close to that I'd imagine...

 

that was without a tank and pump.
