i feel that many people think its a waste of time to let the black diesel to settle. but think about this. when you have the black diesel setting in a gas can or jug my may notice heavy oil at the bottom i don't know about you but i don't want that stuff building up. so it makes sense to do a little work in the begining to get a good finished product. thats my 2 cents.

 

You should also check out Filtermags, available through Jegs or Summitracing, and in sizes to service compact cars to semi-trucks. I run them on my vehicles and cut open the old filters, revealing the outline of the magnet in fine metallic powder. Better on the wall of the filter than running through the engine. Of course, this will only collect magnetic particles,but it'll get just about all of them, regardless of size, and keep them out of the filter medium.

 

If your worried about it building up in your fuel tank it won't or if it does very little from the movement of the fluid in the tank it's sorta like mixing gas with two stroke oil you slosh it around by shaking the gas can after putting both together Why waste any black gold just filter it

 

and your pick up line/pump sucks from the bottom so nothing will get the chance to build up

 

I've been running oil and hydraulic fluid in my 2000 Dodge since last winter. Everyone I tell this to is amazed and asks me "how do ya do that?"

Here's how:

YES - all you have to do is filter it to TWO microns. Don't listen to the people who have obviously never don it. All you'll get from them is that to clogs up your pump, or it'll destroy your engine, etc., etc., etc.

What the naysayers who have never done it refuse to consider, is that your stock fuel filters are only 10 or 20 micron filters!! Some are as high as 30!!!! Do you realize how small a frikkin' micron is??? It ain't as bid as a rock, that's for sure!!

NOW.........here's where you have to listen to me. You HAVE to have a good aftermarket transfer pump on your truck in order to burn used oli or hydraulic fluid. If you don't that stock piece of junk on your engine isn't going to pull the "fuel" up and out of the tanks. Lemme repeat that: YA' HAVE TO HAVE AN AFTERMARKET TRANSFER PUMP TO RUN USED OIL!!!!

So it's 1. Filter oil to 2 microns...................and 2. Get an AirDog transfer pump and you're good to go!!!!

As for the ratio? I've run up to 100% hydraulic fluid and up to 75% used oil this summer. The hydraulic fluid smokes more and will give you a little less power than oil will but it all burns great. I ran 50% used oil all winter, but needed to used a bottle of Howes below 10 degrees.

As for 1 micron filters, are you kidding me? That's tight enough to filter out additives for god's sake!!!! 1 micron filtration is simply NOT needed.

I hope nobody believes anything I say here, because when you do and try it, my FREE oil sources might dry up and I'll have to go back to that high-priced stuff!!!!!

As for filters look for a Bio-Tek dealer and get them there. They have a line called "Microglass" that's designed for the purpose. And they're not expensive!!

FILTER YOUR OIL BEFORE YOU PUT IT IN YOUR TRUCK TOO!!!

 

I'm running my 94 7.3 IDI turbo of 100% used motor oil, filtered to 1 micron. Using just a drill pump and home inline water filter setup. been running the oil, with ATF occasionally mixed in, for about 7,000 miles now, no issues. Was using 5 micron filter before that, but was going through fuel filters like crazy.

 

I would have to disagree on this. There is no such thing as too much filtering when it comes to WMO. I bought my setup from PA biodiesel supply. Joe is a good guy to deal with. He forgot to ship my drum when I ordered from him, he called me and told me, offered to send me a gift card to Northern tools, I told him, not needed, I just need the drum. But I digress, my back story, I'm a mechanic for a landscaping company, I have basically more WMO then I can use at any given time. I have 3 drums at work, so the oil settled for about a month before it even gets into my processing stream. When I transfer it from work to home, I use 5 gallon buckets, the buckets have filters from dudadiesel, starting at 600 micron, 400 micron, 200 micron, 100 micron and finally 75 micro. From there it goes into another drum at home, then pumped through a 15 micron water separating filter. My mix is 50% WMO, 30-35% D2, and 15-20% RUG. There are also times when I won't use any D2, just WMO/RUG and add it to what is already in my truck tank. I will pump this and circulate it in my processing drum for a couple hours, just to mix it up, then start centrifuging it. I spin it for at least 24 hours, not all at once, but maybe 3-4 hours at night during the week, and most of it will be done during the weekend. I don't like leaving stuff like that running unattended for extended periods of time in case of a failure. I would say centrifuging is the best possible way to filter the oil. Maybe this is a little overkill, but I don't think there is a way to filter the oil too much. I would be more worried about dirt in the nozzle of the local gas station then I would about my filtering process. If anybody is in the Raleigh area of NC, or would like pics I can show. Everybody has their own process and what works for them, you also have to think that in Europe their engines are built to different standards regarding pollution, Im not an expert on that, but would seem that they have higher standards regarding factory delivered vehicles. I do know that there are alot of members on the TDI forums who have deleted every possible emissions device and still passed the smog test.

 

Your filtering "process" as you call it is nothing short of comical. Unless you buy a lot of Donaldson stock why the heck use all those filters that really aren't filtering anything out of the oil when all you have to do is use ONE 2 micron filter and be done with it??

I think most of you people who venture into this waste motor oil thing are forgetting that the oil WAS filtered when it was in the engine!

So if it was already filtered to 10-30 microns (as with a standard oil filter) why the heck do you think anything 600 microns is going to be in it? Does that make ANY sense to you??

What's more comical is that AFTER all that screwing around and filter buying you actually run it through a centrifuge too?? If you do why spend all that money on filters??

I'm thinking you HAVE to be an engineer!!!!!

 

EZstrainer | biodiesel supplies = $20 one time purchase
Goldenrod Replacement Water Block Fuel Filter Element — Fits Item# 17041 | Oil Filters Fuel Filters| Northern Tool + Equipment = $13 every 6 months
Not going to buy a whole lot of stock in Donaldson that that price.
Let educate you on why so much filtering, I guess you have never changed oil under a skid steer or loader, hint...they have alot of dirt on them. Or maybe you never had the A/C drain drip into your catch pan. Maybe also you keep your catch pan in a hermetically sealed pouch so no dirt gets in there. I don't have the luxury of sealing my drain pan, it sits on a shelf and grass, dust and spiders wind up in it. I dont keep my oil supply under my control, hence anybody COULD pour whatever they want in there. For the most part I have control over it, but there is nothing to say one of the guys can bring his own oil in on the weekends. I guess I could just use a 2 micron filter, hope there isnt any water, dirt or anything else that would cause it to go into bypass mode. I do it this way because it works, if your way works for you, keep doing it. This isnt about who has the perfect way because the perfect way would be using catalyst crackers and heat exchanging towers.

 

Sounds to me like you need to be mopre particular where you get your oil than how to filter it.

I don't get mine at the busted knuckle garage - I get it from reputable sources and never (as in NEVER!!) let my draw pipe get closer than 3 inches off the bottom of their containers......hence no water and no junk.

No one has to "educate" me on anything about running oil in my truck. I've been slammed on more than one forum for doing it and I'm glad I have been because as long as people don't believe in it my sources won't dry up!!!!!
