Used engine oil.

[mocetane]

OK, I decided to copy others on this thread and I just "won" a ACME 6100 Juicer on ebay.
Now I have to figure out that was decided as the best way to fill in the screen on the sides of the canister.
Epoxy Resin vs Fiberglass resin ?????(Sans the Glass mat)

Next question:
Where is the best place to drill the holes in the canister?
1) near the edge by the screen
2) in the middle
3) or near the inner lip ???

Another QUESTION:
These impromtu centrifuges are 1/10th the cost of a "real one", but they also run at 1/2 the RPM's.
ACME is 3600. Fuel/oil centrifuges run at 7200 RPM.
I don't recall this being an issue that was addressed in the 23 pages of this thread. Also what is a good temp. to heat the oil/atf for centrifuging ?? 120-130 deg. F ??

Would a adjustable temp hot plate or food warmer do the trick if you did not drain/pump the supply drum all the way down?

I plan to run WMO/ATF/WTF mixed with diesel in a 1991 5.9 cummins with 300,000+ on the clock. Runs good. Has been well cared for.

I have more questions too...next time
Thanks for any help.

I didn't use epoxy, I used waterproof metallic duct tape. Never drilled holes. I've not heated my oil yet, but I've let it sit out in the sun before running it. I use a ball valve to control flow from the holding tank to the centrifuge.

Great. I have some of that stuff already !!

OK, Next Burning question: Does this system get water and/or antifreeze out adequately??????????????????????

I have an unlimited supply of WMO/ATF for the salvage rate of $.40+/- per gallon that a couple of tranny shops will sell me. This is the price they get from the bid time collection contractors.
I am still looking for free oil.
I just started looking last week. Need to find some small time shops...but they are dissappearing like common sense these days.
The pain is that one of trans shops does engine work too and they get emulsified goo from blow head gaskets mixed in.
All WMO and ATF goes in the same tank at the end of the day.
I was thinking of just pulling off the top of their tanks and then letting my raw WMO/ATF sit and settle for a few weeks and pull from the top on mine for filtering and centrifuging.
Hope that will get the bulk of the water and antifreeze out.
The antifreeze scares the crap out of me... don't know what kind of carnage it will cause.


Thanks again....

If you ran it slow enough I'm certain it would. I mixed up a heavy emulsion and was seeing the water beginning to bead up. This stuff was nasty, way worse than anything you'd run. Let gravity do the work for you on that though. Time is your friend when it comes to this.

Are you referring to the flow rate you run the WMO thru the centrifuge here ???

Do you use bag filters or the yarn/cloth wound type??

I plan to gravity filter to 10-5-1or2 microns and then centrifuge.

I am going to try small batches first until I get this figured out a little more.

Thanks to all for great info and ideas.

Every few years you get this line of BS coming out. I have been around long enough to have been involved in one of the earlier attempts of this when I worked in a logging camp. They bought a great big unit that had two large 750D luberfiner filters with the gypsum in them to take out the acids. The oil from the filters was not used, that on a 12V 1710 Cummins still left about 25 gallons of oil. It was pumped threw the first filter hot out of the engine for about 20 min, them mixed with fuel out of the tank about 50/50 and circulated for an hour threw the second filter, then back into the tank, it had heaters to keep the mix flowing properly. Their was a great amount of patting themselves on the back as they were going to save 1/3 of a days fuel and didn't have to dispose of the waist oil. The trucks, 850 Kenworths had huge fuel tanks, they got the oil changed every 45 working days. and greased every 15. About 30 days into this we started to have injector problems and these were the very early PT injectors, just a plunger in a sleeve with orifices, about 300 lbs injection pressure. They started to seize up. We also did this in the 849 Kenworths with 12V 71's Dry blocks they lasted about the same time and when they seize the rack sticks and the motor wants to stay at the same power out-put as it has when they seize, "possible run away". They all had automatics so the driver just pulled the emergency shut down and called a mechanic. I made a fortune in overtime as there were a lot of companies that did the same thing, in the area, there was a shortage of injectors so you only did the ones the were sticking. the clearances now are a whole lot tighter and the pressures a hundred times higher. The injectors in a Cat Huey is 700 dollars and about 300 labour, I don't know what the cheap they use in a Power stroke costs but it sure seems not to be very cost effective to me. Unless of course I do the work then go for it.

You have addressed some of my concerns. You obviously
have the experience that few of us have.
I just wonder with all the filtration that you did with the
big filter units that you had back it the day, how fine was the end result. Were they getting the used oil filtered down to 1 micron or less??
Just curious...

Thanks....

[jpringle3@hotmail.com]

In those days you would be lucky to get filtration down to 15 micron. The soot in the used oil would be like running your engine on lapping compound even at 1 micron. The acids in the oil would get after the aluminum and what ever else. I would never risk a hundred dollars to save ten.

IMO This is good advice,it's great to see someone with the knowledge and backbone to tell it like it is.

I don't know how much more experience you need. I ran wmo in my ferd idi for 4 years & over 40k miles at rates as high as 90% the nozzels & IP had over 160k on 'em when I started & are normally replaced at 100k I finally replaced them at 230k after saving over $3,400 I think it was well worth the small price of a set of nozzels & an IP which totaled less than $300 wouldn't you ?

15 microns and ~1 micron are very different figures. But i would think the friction modifiers and acid would be of most concern (but I am just guessing)

You can't argue economics in this thread. Even if the math adds up.
