- A friend lent me his centrifuge to try cleaning/recycling used dirty oil from my machines, It was interesting to see how much rubbish it takes out of the oil.
My other channel (Angry Ram) - • What happens when you ... - แนวปฏิบัติและการใช้ชีวิต
Marty, long time subscriber here from alaska.... this is right up my highest attention level as it brought back a great memory on a job I worked on.. the Valdez Oil Spill, a tanker went aground and the stories about it went world wide. I was on clean up with a machine powered by a seven cylinder Deutz engine,... a very loud air cooled engine with just a perfect setup to run three centrifuges under it so it could separate oil from the sand and rock on the beach. It did work alright but it was a nasty thing to clean that crude oil from it... so when we packed up and left, we didn't bother to clean those chambers. Fast forward about two years with no more work for it and we needed some cash so decided to scrap the machine and part it out. We took those tanks out and the first one sent straight to the crusher so when we tried to take the next one... they resoundingly said clean only! We needed that cash bad so we started cleaning up the centrifuge of the nasty crude, backyard fire to remove the crude praying not to get caught with the smoke from that fire which did not burn well at all or a losing deal. That turned out a blessing though cause this is where things got interesting.... gold and oil have a similar weight on the periodic chart and so imagine our surprise when we found a significant amount of gold flake from that sand off of the beach in Valdez. I and the other guy had a lot of money we figured to never see back and so owed money yet for materials. We found in the waste and spots in the cylinders a lot of gold at thirty two dollars a ounce then as so even... it came to nearly seventy thousand dollars in gold we had no clue was in this machine... more if we had kept the one we shipped out for scrap. I did tell them what we found and so they retrieved that crude from the cylinder once found again. It paid off our debts, and put a little cash in our pockets as well. Us guys though who catch the bug called hobby mining never wind up with much cash in the end and we could not afford to build another centrifuge like our first one.... I just know it would of worked in some of our streams here
Fantastic story!
What part of AK?
Oil separators have been used in ships to filter heavy fuel oil to the engine for a long time. Heavy bunker oil is pre-heated first, then through a centrifugal oil separator, then through particulate filters before the engine. Big things, those separators, with a lot of widening chambers (cups) in them. Same principle as in the video, just a lot more of them. In a centrifuge, the viscosity of the fluid + the diameter decide the optimal speed for a certain size contaminate. Your crude little experiment showed us all that it works, but you need a more controlled environment to get a good result. And a better centrifuge, of course.

Dear Morgan Adair
👍👌👏 What a great story with a very surprising result. Congrats. I like happy endings respectively I need and want them (especially nowadays). Thanks for sharing this adventure.
Best regards, luck and especially health to all involved people.
I could watch that ram headbutt for another hour or so 😂
I was in stitchers 🤣
💯 that was great 👍
We could.... but he took out the camera.
Needs to work out how to attach a generator to it for even more free power
I have never seen a ram do that 😂
The dog spinning after the tail was great. Then Marty had to say "tell 'em how it works 'eh?" Well I just lost it. Thanks for the much needed laugh!
adorable bull terrier of his.
Who needs a guard dog when you have an attack ram 😁
Ram even sounds like a dog after viciously beating that poor boyant off its rope.
I see where they get the fraze "RAM RADE" from now.
@@Paulman50 I have never heard that in my life and I am old.
Too oath!
your centrifuge will clean down to less than one micron but will not remove the colloidal carbon that makes it look black still. It will certainly be clean enough to blend with whatever and run in non common rail diesel motors. good on you mate, I've been doing this for 10 years and have used over 60,000 litres through my Cummins Signature 600.
oh yeah...I have seen the 10K rpm units clean oil quite well...but they sound like they are gonna explode!
Exactly. Common rails are way too delicate, the high pressure pumps just runs at insanely high pressures, any sort of impurities will do tons of damage. Older diesels are less refined and efficient, but also much much more resilient
You pass the oil through compressed cellulose and you'll remove most if not all of the sludge, carbon and oxide insolubles. I use a dirty liquids pressure pump to clean oil that way. I reuse it in order of degradation through increasingly less important machinery. Ex: car > lawn tractor > garden rototiller > chain saw. Initial setup is a wee bit expensive, but it pays off over time. Where it really shines is on my brother's farm where things are upscaled considerably. Mixed with good oil, you get perfectly usable oil at a reduced cost. And it adds up. We've had several blends and the raw product tested and the compressed cellulose removes all the major contaminants including oxidation issues.
Dunno if it works for fuel tho, never tried it, we rarely deal with wasted fuel.
Do you have some pictures or similar on your setup?
I'm currently using Diesel ship filter catriges and I'm happy so far but I'd like to see how you guys do it
Only diesel or do you burn oil?
The sheep at the end was gold. I could watch that all day.
My first thought a few seconds in was "Oh that poor dog won't be that white at the end of this video." :D
The best method is to heat the oil up to 120c prior to centrifuging it, the high temperature thins the oil out making the centrifugal forces more effective on the finer particles.
Its also going thru way too fast. I would get an electric valve and arduino or other timer so it can be automated and left alone
for water contaminated tractor transmission oil I boil the water off in a 20L paint tin over a gas burner,works fine and oil ends up nice and clear again.
Those mussel buoys are heavy as, and he was bunting it around like a football!
@M&S Paeroa He's actually quite dangerous, one good hit would break leg bones
I used to work on seagoing vessels with separators. It needs a water ring. Vertical: from inside to outside, oil specific mass under 1. Water 1. Dirt etc larger then 1. On top you need a plate called specific mass ring. Its diameter needs to be smaller so it keeps the ,,water cylinder,, in place. You wont be able to get the colour out. Lub oil you take out the dirt and additives new engines need. So it only can be reused on older engines that dont need additives.
Yes, Alfa laval centrifuges for cleaning fuel on ships need a water inlet. These machines are about 5 levels up. Also, these machines are created for certain inlet densities of the filtered liquid.... When I started cleaning used oil for heating the house in a mixture: used car oil + a mixture of mineral and synthetic oils ISO VG 220-460. I mixed these two ingredients in a 1:1 ratio and preheated to 60°C. I used a milk centrifuge from 1935 with an electric motor instead of a handle. With this machine I filtered approx. 2000l per year for 5 years. Then I made something similar with an output of approx. 30 l/min.
Not entirely related but: In the early 2000's my dad drove 300k miles fishing in his diesel Citreon car fuelled 90% by used vegetable oil collected from take-away restaurants and gravity filtered by the side of the road. The other 10% was either fresh cooking oil or diesel, this was mainly in the initial stages while he learned and adapted the car slightly to work better (some in line fuel heaters he custom made as 99% of the issues he had were due to viscosity/cold temperatures over night).
He did his research and got the car in question specifically due to the type of fuel pump used, I don't expect modern vehicles would take the transition as smoothly 😬
If you notice, on engines that have been under cover but haven't been started for say 30 years the oil always looks like it's new. All the particulates sink and the original oil stays on top. I've seen this quite a few times over the years.
Ending made my day :) Looks like a sturdy fella. Determined :)
This channel has given me a idea how to use tools and get the job done.
He was so god darn happy about knocking that bouy over what a wee lad having the time of his life
During WWII my former Boss was on an American Submarine. His job was to "filter and test the oil". They didnt do oil changes, they kept reusing the oil from the diesel engines. I remember him saying something maybe about only having to put in "detergents or additives depending on the test"... He is passed now, so no asking..
That ending was awesome. You know you can do a basic moisture test using the crackle method. Heat up some metal on a stove top to over 100C, and place a drop or two of test oil onto it, and any significant moisture will make it crackle.
You should build an oil cracking plant. Used oil refinery. Quite simple, turns used oil into clean and perfectly usable diesel fuel. I will be building one myself soon. Just look up turning used oil into diesel on TH-cam.
Its good to see Thunder and the new pup on the channel. I still watch the video with Rambro hammering the excavator bucket and laugh.
Get ram bro’s son a job in demolition 😂👍🏻🏴
Thunder was mighty proud of himself!
My Honda motorcycle about 1974 year had a centrifugL oil filter. The engine was spotless and oil always clean. Had a 50mm diameter cup about 70 - 75mm in length. I couldn't understand its process but thats how it worked. You're onto something here Marty.
Love the video of Rambrose defeating the punching bag. He came away looking pretty proud.
I think the problem with the centrifugal cleaning is that you have no way of knowing how clean the fuel or oil has to be to be safe to use.
Hi, every deep sea vessel uses these to clean the oil in the systems and if set correctly work wonders, no oil sellers in mid ocean. Many thanks from Nr Liverpool UK.
An easy way to get water out is to freeze the liquid so the water turns to ice.
Emulsified water will form microcrystals and they will remain suspended - freezing will achieve very little
@@PaulG.x Put some oil and water in a soda bottle, shake it up let it sit for a couple of hours and freeze it. Just setting up a barrel or making a container with a tapered bottom with a drain in it will allow water to settle out. The longer you let it sit, the more water leaves suspension. Heating to remove water by evaporation also removes any aromatic hydrocarbons like gasoline and diesel fuel which are not good things to release into the atmosphere. The centrifuge has the same effect as gravity on an increased scale.
@@tiredoldmechanic1791 Putting some oil and water in a soda bottle is not the same as what happens in an engine. It does not cause emulsification or other chemical bonds between the water and constituents of the oil.
A pointless exercise
@@tiredoldmechanic1791 so you are saying that freezing will decrease the density of the water, making the density difference between water and oil smaller, thereby making them harder to separate‽
@@Bbonno I'm saying that freezing will make the water a solid and it's easy to separate a liquid from a solid.
The ram should be your channel mascot! Launching his entire body into the toy, is a good reason never turn your back on him; but positive interactions will reinforce safety. The centrifuge is a great idea, but as you say the incorporation of heat exchanger would be a good; if you allow the oil to cool before going back into a centrifuge. You could build a filter system using sheets of "qualitative" filter paper designed for funnels which are precut into discs. Or paper towel /coffee filter drip system between multiple giant plastic funnels, if sufficient size / diameter will regulate the flow and improve the capture of fine particles. An oil centrifuge interesting idea, especially for burners.
Love the ram playing with his toy! That's great. I'd try draining the oil through a coffee filter, screen or something and then run it through the centrifuge maybe with that much sludge in it. Couldn't hurt.
That is one very cute pup!
Thats a Spuds McKenzie Dog. I'm glad He's at a Good Home .LOL..Sense Budweiser is going out of business..LOL ..HAHA .for it's Shenanigans..LOL .I've never seen one of those Spinners .Seems too work good .Great Video..
I spent years on diesel submarines where sometimes on long cruises...diesel fuel was actually stored in the bilge along with bilge water. As the fuel was need we sent it through Sharples centrifuges and also used DeLeval separators...Worked every day for every diesel submarine ever made...
I love how that ram when he took down the ram butting bag the look was priceless almost like saying “I win” 😂
That's really interesting, never seen anything like that. I think you've got the right idea in running it all day in a cycle. It might be interesting to buy a cheap oil filter and run a pump before the filter to send it back to the center of the centrifuge. Neat stuff. Thanks for the video!
A marine water separating filter would work also
A cheap filter won't do anything as they don't filter more than 10-20 microns
Thunder is a chip off the old block. Strong!
Marty, when I was in the Arctic, we used an Alpha Laval centrifuge to lean up our air compressor lube oil, it was multi pass to clean up the condensation in the oil.
Our large diesel engines, EMD, had dual Oil Spinner centrifuges on each, that could be swapped, with the turn of a ball valve. So as to run continuously, while one Spinner could be taken down, and cleaned.
Neither system was single pass.
Best wishes from the far North.
So wait, the centrifuges were literally part of the circulatory system of the engine? As in, it was constantly cleaning the oil and pumping it back through the engine? And that was important enough to be worth the loss of total horsepower needed to run the pump and centrifuge?
@@skeetsmcgrew3282 On the EMD's they where mounted on an external rack, beside the engines, tied into their oil systems.
The Alpha Laval, was on a cart, that was moved between the Large compressors.
He broke his Toy. He came over to Dad to say Hey fix my toy...LOL...HAHA. That was priceless at the end of the video .. Thank You ..
If anyone could rig a better centrifuge it's you, Marty. Man, it's good to see to see Son of Rambro! Just a chip off the old block he is! I cheered when he defeated the punching bag at the end and then attacked the camera. Just like his daddy!
After the centrifuge...........the black diesel blend should go through a 2 or 4 micron filter, if using standard filters (only 60% efficient) use 2 filters in series. Centrifuge "spinners" have been used very successfully on trucks ( Mack) and heavy machines for a long time. Even the Soviet, Kirov/Belarus tractors used them. Black diesel works just fine, especially in older diesels.......probably not in the late model common rail engines.
Mixing it with a bit of fresh fuel never hurt either...the nice thing is the waste oil once centrifuged provides MASSIVE lubricity to the injector pumps, especially with todays low sulfur junk they sell at the pumps
If filtered down to less than 1 micron, the injection system is not the concern. Newer engines are now equipped with Diesel Particulate Filters (DPF) and Selective Catalytic Reducers (SCR). The EP additives in oil consist of Zinc and Molybdenum. Those metals become oxides in the combustion process, and those oxides form an ash with a much higher melting point, than the temperatures achieved in a regeneration cycle. That ash will clog and cause restriction in the DPF, and foul the SCR. I would only ever recommend "black diesel" in older engines without post exhaust treatment.
@@vincentrobinette1507 yes, DPF systems are almost exclusively found on COMMON RAIL engines......large and small. Pre-common rail era engines as a rule DONT have DPF. Blocking the DPF with ash is a minor problem compared to the potential damage to the high pressure common rail pumps which are very fussy. If you get dirty fuel,water or even higher than 5% biodiesel through a common rail pump, problems can happen.
Way back when we simply dumped the 14 gallons of used oil from one of the big trucks into several fuel tanks and their inside filters would catch any particles in the oil before it hit the pumps and injectors,saved a few bucks off of fuel costs when considering each trucks oil had to be changed every 6-8 weeks depending on its miles ran... Never had any issues with pumps or injectors due to used engine oil. Works great in off road equipment also..
Hahaha the ram at the end was fantastic! Such talent knocking on that old float!
I used to work with a fellow named Marty who has a Bull Terrier. What a coincidence!!!
Water separation with centrifuges is really common. That’s also how cream is separated from milk and unsurprisingly exactly the same equipment is used for both (same manufacturer).
The water comes from the wall of the centrifuge and the oil from the inside.
R.I.P Rambro, May your legacy live on
oh my goodness, you never know what you're going to get on youtube. i clicked not really sure if i was all that interested in centrifugally cleaning oil, and i get a ram playing tetherball and panting like a dog. tremendous!
When I worked for the fire department I managed a project where we needed to replace our leaking underground fuel tanks and bring them into current environmental compliance back in the 1980s. The company we used had an industrial size centrical system that operated fuel from water and also removed significant debris and suspended particles from diesel fuel. All the fuel he pumped out of bad tanks, bad by most standards were cleaned up using the centrifuged and he used the fuel safely for the businesses purposes saving a lot of operating costs.
To get the best cleaning action, run the centrifuge at the highest possible rpm, flow rate of the oil as low as possible and the oil needs to be pretty hot, so the viscosity is as low as possible.
Great looking pup Marty
the ending is spectacular. that animal has some stamina!!
Reducing the flow rate to almost a drip would help a lot. You are right about not wanting to run "black diesel" in a newer vehicle. Oil has EP additives like zinc and molybdenum, which will oxidize into an ash that has a much higher melting point, than is achieved in the DPF during a regeneration cycle. Black diesel is fine in an older engine that doesn't have a Diesel Particulate Filter, (DPF) or Selective Catalytic Reducer. (SCR) Those components will be fouled by the EP additives of engine oil.
A centrifuge like this would be ideal for recycling oil in lawnmowers, roto-tillers, portable generators, water pumps, wood chippers, or anything else with a small engine. These engines typically don't have oil filters, so passing the crank case oil through this centrifuge will filter out much finer particles, than any media filter. You could afford to change the oil in these engines more frequently, since you're cleaning up the oil after a few hours of use, and reusing it. A typical engine filter only filters down to ~20-30 microns, this spinner can get particles down to less than 1 micron, if the flow rate is reduced to 1-4 quarts per hour. A filter that filters only down to 25.4 microns is admitting particles up to 1/1,000 of an inch. NOT FINE ENOUGH! This spinner can do more than 20X better than that, if the flow rate is low enough.
I made one of these as a kid for my waste vegetable oil cleaning. IT was great, thousands of gallons I ran through my diesel trucks. I would screen filter first then centrifuge then paper filter. Saved cost on filters long term
I'm amazed by how many centrifugists you have watching your videos
If it was that easy to clean up oil then 2nd hand oil then we would get paid when we hand it back for recycling. Great idea for keeping the Ram occupied.
It would be interesting to get that oil/fuel analyzed for particulate size post spinning and see if adding a small micron filter system would clean it up more? Eventually you will have your own refinery!
Found you through RamBro & stayed for the tinkering. ✊️🤙
The little spinning dog made me smile, but Thunder? he's the limit.
This is mostly what is done at oil recycling facilities.
When you remove the water, the water will need to treated before discharging to environment.
The final step is catalytic hydrogenation.
If you do distill it, you will usually get three fractions which produce a Diesel fuel, a thin and thicker lubrication oil.
Nice community and channel content , subbed.
Love the bull terrier pup, they're the best dogs!
Puppy wins!! Too damn cute.
Thunder comes to you after his little workout like a happy dog panting over his exertion. At least the sounds of this Thunder doesn't mean another round of road and drainage rebuilding.
When I was a kid living on a farm in the UK we used to make our own butter , milk was from one old cow kept for that purpose. We had a centrifugal milk/cream separator , hand operated. My job was to turn the handle to get to the required speed then turn on the flow of milk and keep turning. Skimmed milk came out of one outlet, thick cream out of the other. Speed was controlled by a bell which sounded until you got going fast enough, damned hard work for a youngster. It must have had quite a high gear set up to get the actual separator bit spinning fast enough. I bet there is a lot of these thrown into sheds and barns now and replaced by more modern stuff. Ours was actually set into the dairy floor in concrete, it required some real effort to get it going. Maybe it would separate oil/ water/diesel etc. Just a thought it must have been about 60 years ago, time flies.
This gadget is far too clean and nice looking to be used in a Marty T video.... look forward to seeing you make one out of old rusty parts :)
And maybe not the best activity for a white pup!
WRANGLER, read you complements first then you will get the gold. First things first, I love watching your videos because you are one of the calmest mechanics on the tube. Your approach of dry humor and a bucket of common sense is fantastic! So I am in America in Texas, I have been broke when it came to my trucks and equipment most of my life because the family gets the lions share as I am sure your does too. I found a way to filter oils and reuse them on the cheap. Take a leg from a "WRANGER" pair of denim jeans and sew the bottom shut. Pour in any oil and let drain in to a bucket. Wrangler denim will filter any oil to 10 microns.
The Navy uses this method however with multiple centrifuges in one unit for various particle sizes. The centrifuges are closely stacked and conical shaped. The centrifuge also breaks down the cleaned oil when cleaning it so, while it works, you cant do it repeatedly without adding additives.
Duuuude you hung something for it to ram!? You truly are a good human. Thank you.
FWIW I have the oil filter unit from one of the diesel Landcruisers. It's a large contraption that bolts to the side of the block, and it does have the usual spin-on paper filter but there's a dome on the opposite end that's about the same size as the big paper filter. That's the spinner part of it and like your machine it centrifuges out the impurities in the oil.
Is that on one of the older Landcruisers??
Silly question, never mind!
@@mikescudder4621 From memory some Toyota 2H engine variants came with the centrifugal oil filter. Land Rover TD5 engines also had centrifugal oil filters.
Hahaha at the end Marty ! What A Ram , should have his own show 🤣
I think I have a headache now... Interesting centrifuge idea. Need to work with it more. Thumbs Up
Years ago I had a fishing boat and swapped the 6 Cylinder DAF Diesel out for a 8LW Gardner. I installed a centrifuge oil cleaner on the Gardner. I can't remember where I bought it from but was some engineering company in NZ. It fitted in place of the oil filter. It had inlet and outlet hoses and you had an adaptor that bolted on where the filter was. You simply removed the outer casing periodically and cleaned the junk out. I probably wouldn't use it as the main filter on a modern diesel engine but it seemed to work well enough on the old Gardner. I am sure that you could set something like that up to run continuously in a loop but I think it needed quite a bit of supply pressure.
Centrifuges are used to separate oil from water in the water treatment plants on offshore oil rigs before discharging water to sea. It is a very fine tuned setup. Rotation speed, angle of cone in centrifuge and feeding volume needs to be very exact to get a good result. If tuned and with repeated passes you should get a better result.
This probably won't matter much, but when I was in the fuel business, we used blue rags to clean up fuel spills. They have a VERY cool feature - they will physically strain water out of diesel fuel. Simply line a funnel with a towel and filter the fuel through it like a coffee filter. All of the fuel runs out the bottom of the funnel and the garbage, debris and water stay in the funnel. It's the damnedest thing I have ever seen. Many, MANY gallons of contaminated fuel ended up in my oil burner when I worked that job. Even foamy, mixed fuel settled and strained. The rags can be used over and over again. They simply DO NOT pass water.
We had 2 centrifuges running each with 13 internal filters each 2ft by 4 inch inside the centrifuge canister.
That was for the new oil before going into the engines, it was amazing how much crap came out of brand new Diesel engine oil. 👍
Thunder certainly worked up a sweat, he's got some power!
Glad to see the Ram's are still kicking (or I guess smashing into things). That centrifuge is pretty sweet! I knew a guy that had one and would run waste oil through it, then filter it, and then mix it with diesel. I forget the ratio he used, but he ran it in his farm tractors and old IDI diesel truck. He figured that it saved him quite a bit over the years. This is such a great idea to get more use out of something that would just get tossed!
I used to operate a similar device for removing air from acrylic adhesives used in ultra-thin coatings. It was hooked up to a vacuum to remove the air bubbles, but the machine I used had a scoop on the inside of the centrifuge to pick up the material rather than it spilling over the edge. It was a fine balance of adjusting the material adder and vacuum valves. Anything that spilled over the edge of the spinning bit was usually full of bubbles and sent back into the machine.
It was kind of fun to use for a typically boring factory job.
Some boring factory jobs are fascinating.
My one was playing with the rumbler, carefully tending my "pet carbides" as they wore over the years.
Fiddle with the weights, try a different combo every day, see what results it has...
Read centrifuge and immediately thought are you separating honey, making mayonnaise or cream. Neat machine. Thank you for posting such entertaining videos. Best wishes from the UK.
I only came here to see the Bullie. Lovely pup.
I built a filter cart that I could take into the field and pass large machine (over 50 gal tank) hyd. oil through while I was doing some other service. It was just a small electric pump with a large 15 micron and a 5 micron filter in line. It would help keep systems clean in between changes. Perhaps you could pass your spun up oil through a fine filter afterwards to let you sleep better.
It can’t remove anything dissolved in it. But as long as the particles are out, it is safe to use as a general lubricant, as it will not have any abrasive sediment leftover.
That dog is funny lol..he was demonstrating how a centrifuge works
Different, haven't seen a machine like that. Learn something every day. Thank you for sharing. Your pup is a treasure!
Happiness is seeing MartyT new release!
Definitely interested to see more on this, really like your idea of running it long term with the heater etc.
The applications are wide too, waste vegetable oil springs to mind in particular
Amazing ram footage, it's been a real journey with those guys.
What did you say his name was Rambro? Unreal man I’ve never seen nothing like that. Thanks for sharing friend.
Gorgeous terrier there.
Good job.
It would be really cool to see a comparison of what you suggested with the constant drip at 5 10 and 24 hour intervals as compared to fresh oil!
Love from Canada 🇨🇦
P.s love the ram being a speed bag menace breaking all your stuff lol
"He came, he saw, he conquered"; his boat bumper !!! Good intel on the oil cleaner. "Thanks for sharing, and too, take care and stay healthy; because we all look forward to more of your vedios and projects!
Marty, we loved watching the sheep get a workout in!
If you try some of the techniques that have been recommended to de-moisture and filter the various fluids, you way want to document processes on various batches, sample and label the batches, and send the samples off to oil quality test for some results. That might tell you which processes on which oils are most effective and would be the best use of your time.
Watched Master Milo deep fry straight 50w to dry it!
I think that letting the clean oil also pass over a cluster of strong magnets would catch microscopic iron residue in the oil.
There are many different steps to take to clean oil, but distilling it is probably the most efficient.
Just be aware that new oil has additives that are there for various purposes like catching contaminants or act as an anti-foam in hydraulic oil.
Love the Bullie! I have had two myself and they are like a ''Mini Ram'' themselves! Best Dogs EVER!
It should be pretty easy to remove water from oil using one of two chemical techniques.
1. Brine washing. Make a concentrated brine of NaCl (table salt) and water (Concentrated: you can't dissolve any more salt in the water. This brine should be as salty as possible). Pour this into the wet oil, and shake it up, and let it sit. The concentrated salt brine should absorb all the water out of the microscopic droplets dissolved in the oil. Salt should not dissolve in oil. The brine will separate, and you will end up with a dirty brine layer and a dry oil layer, where you just had wet oil before. You should be able to centrifuge off the brine, or siphon off the oil.
2. Epsom salt, aka MgSO4. Epsom salt is the wet version of Magnesium Sulfate: MgSO4 with 7 H2O molecules. Heat it to 200C in an oven for two hours, and it will become dry MgSO4, which has a powerful affinity for water: it wants to have its 7 H2O molecules back. (It may come out of the oven chunky; you may need to crush it to get a powder again.) Put it in the wet oil, and it should suck water out of the oil. You can then use the centrifuge to separate the big wet MgSO4 grains from the dry oil.
3. For best results, brine wash them MgSO4 wash.

Thanks for the angry ram update! It was fun to see the animals again! As for the diesel or oil, after running thru the centrifuge, you could run it thru a fuel filter or oil filter and see how much better it looks. Maybe then it would be worth burning in a vehicle or using in a decent tractor???
nice, especially the end, that was unexpected! 😅🐏
Ran some centrifuges for years on large quantities of turbine oil , only helps to remove water. Very time consuming systems and won’t remove any microorganisms or dirt, a good filter system and a loop tank feed will sometimes get your oil cleaned up. We’re talking thousands of gallons of oil over weeks and weeks of work. If you’re oil really does have large quantities of water in it you can heat it and remove the water by draining it off the bottom of the tank first.
Marty I recall watching a television show forty or so years ago which was based on examining innovative technologies and one episode I viewed investigated a centrifugal device for removing contaminants from engine oil.
If memory serves the program initially commenced airing as Towards 2000 in 1981 but was renamed Beyond Tomorrow in 1985 then was ultimately cancelled in 1999.
The device I recall was based on a 'cyclonic' principle and designed to be permanently installed on trucks and other heavy commercial vehicles after which it received some exposure in publications pertinent to the transport industry.
It had a transparent reservoir so purified oil it contained could be easily examined and so far as I am aware it worked extremely well and held promise for substantially extending service intervals for engine oil.
The invention attracted quite a bit of interest in the transport industry and was installed on a number of vehicles.
But then it seemed to quietly disappear without any of the fanfare you might reasonably expect such an environmentally sympathetic concept to attract or sustain.
I also recall speculation circulating at the time to the effect that concerns with a vested interest in wasteful consumption of lubricating oil and disposable filters may have contrived to suppress the device and ultimately remove it from the market.
i think if you use the centrifuge regularly and needle valve (tap) for better flow control would help getting the settings dialed in quicker
the sheep at the end made me smile ear to ear, he needs his toy fixed up since he broke it. he looks like he could be side channel of him playing with his swinging toy when his passes thru.
there's a channel i follow "The NotSoGrand Garage" that has been running his diesels on "black diesel" (engine oil mixed with stale petrol or diesel) which has done many experiments with his centrifuge lately, heating, thinning prior etc.
I was just fixing to mention his channel.
The pup is growing quickly, it looks to be calm and friendly.
