Got a good reliable link to buy a centrifuge kit?
AltFuel Anyone making "black diesel" (WMO/ATF/hudraulic oil) out there ?? (1 Viewer)

I have contemplated this one..https://www.scintex.com.au/products/oil-centrifuge
The early 2h had a centrifuge from factory, unfortunately they stopped including them on the late 2h. I don't think many manufacturers had them ome, certainly wouldn't now. Some trucks do have them from factory. They do make a lot of sense.
They need to spin around at 70psi to be optimal.
Side note on the oil bypass is the germans wanted to get to sth. america without downtime changing oil in submarines after wwii.
I can change oil whilst the engine is running on my bypass, would like to add a centrifuge but finances is always something. Use to take out half a liter and replace with fresh every week but now just still do the every 5000km.
But I can drive 1000km on hwy run, with fresh oil and my oil is still quite clean. I did an oil bypass rave if you do a search. Very happy with it. I have just over 300k kms on the engine and recently got 9.3l per 100km which I consider having clean oil ,amongst good maintenance as a contributing factor.
Carbon builds when revving below 2000rpm on the 2h, so idling sucks for any combustion engine for that matter. Centrifuge would not be effective at idle either.
Redline suggests cleaning an engine by giving it 3x oil changes in succession ,they do sell oil!,
but a gentle way to do it.
I looked into recycling oil, but the expense to set up does not outweigh the purchase of fresh oil unless considerable quantities is recycled. Oil also looses it's lubricating qualities and structural integrity as it is reused progressively.
But set up on a running engine, you would be able to run on cleaner oil which = longer lasting engine.
Hmmmm.clean oil all the time.
Thanks for the reply but this post was intended for using a centrifuge to clean used oil to be used as fuel.
Thanks but I already have a bypass oil system for my engine. (It’s like getting an oil change every 10min)
But that’s some good history about the factory 2H centrifuge.
sorry, I have met a fellow who used it as fuel mixed with kero, he was happy but never entered civilization and not concerned what it smelt like or what exhaust looked like. Just cheap and nasty.
I cannot imagine how it could not smell horrible and do carnage to injector nozzles.
I have used veg oil and used engine oil to fire ceramic kilns using a drip with air pressure into a heated chamber, the engine oil smelt sickly, really evil horrible, feel it in the stomach. Both have impressive flames.
Ever since smelling the wmo I cannot imagine using it to burn. My experience.
Maybe if it was super cleaned, but even then, I have used clean engine oil as bar oil in chainsaws when no choice, that smelt horrible too.
I am yet to read, see or hear off someone burning black oil celebrating the exhaust fumes. I guess ok if not driving where there are people, just don't inhale.
I think if the effort was made for alt fuel, biodiesel is the go. Smells good. After all, the first diesel engine ran off peanut oil.
They certainly use wmo for tobacco drying kilns, few more chemicals inhaled no difference..
It really works well to deter insects from timber, no animal goes near it as it smells really crap.
Simple test would get some diesel, veg oil, wmo and burn it with flame. Take note on combustion volatility, carbon and aroma. All of them have lots of carbon.
My conclusion of all the wmo oil I produce is to just give it to the folks who recycle it in bulk, sometimes I use it as oil baths for used car parts to prevent rust.
Like tyres, wmo is part of a collective, unavoidable pollution if we are going to use our combustion vehicles. EV's shall create another pollution.

Good day all 
16 year long thread !
so anyway anyone run either a 2h Cruiser or 2l/3l Hilux [years like 80s-90s] on black diesel successfully for a few years/few10s of thousands of miles/ks ? Specifically any problems /solutions to coking injectors/swirl chambers/swirl chamber outlet ?And like did centrifuging or running 2 tanks or preheating or water introduction to intake etc fix it ? Thanks

Thanks I have recently in the last month met two youngish diesel mechanics running on sump oil in their 2h's. The more experienced would do 1000km in a go and go back to neat diesel. He lets the sump oil settle in a tank before transferring it to his 2nd fuel tank. Have not heard of long term longevity like in years, from anyone in person. It would have to coke up injector nozzles, as they do coke up on neat diesel, so it would be more so on sump oil.
But yes free fuel , and still I imagine it to be extra stinky.
Other fella had a good phrase, could you imagine an electric bulldozer! not possible certainly not, as of yet.

g,day , how did the 2h end up doing on the wmo lomgterm ?
So 14 years down the line , are you still running wmo and if so in what motors
, are you still running wmo and if so in what motors It works Fine!
After searching the web and reading various forums I decided to filter down some old sump oil I had sitting around. I started with a pure gravity feed through a 1 micron mesh bag - and mixed it with ordinary diesel at ratios up to 70% oil to diesel.
All ratios below 30% show no difference at all. At 50% oil and diesel, the "nacka nacka" noise of the tappets shut up and the engine had marginally better power available in the low rev range (800 to 1100 rpm). At 70% oil in the diesel, I started to blow a little smoke when under power (Such as 3rd gear and up a steep hill). As I had never blown any smoke at all prior - I backed off the mix to 50:50.
I've run about 500 liters through the vehicle so far - and it seems to love it.
So - can we do it? YES
Does it harm our engines? Only if not filtered properly.
The existing oil filters on the vehicles are a bypass type that clean around 80% of everything going past to around 25 micron level. According to the Automobile Standards Association, some 70% of all engine wear is caused by particulate down to 4 micron in size.
Check the links on the forum at:
Freel2.com - View topic - 2-stroke oil and diesel
also:
Bio-Diesel and Alternative Fuels - Diesel Forum - TheDieselStop.com
to start tracking the info down for yourself. There certainly is a lot of info if you are willing to do a little research.
Mercedes Benz themselves took a fleet of demonstrator vehicles to China and added 2 stroke motor oil to the fuel at a 200:1 ratio to overcome the damage being done by low sulphur diesel.
As my vehicle has over 530 000 kilometers on the clock - and I love my truck - I want to look after it. This is a good choice in countries where the laws around using diesel alternatives are not structured to win tax dollars. [It is my understanding that folks in USA are risking a form of tax evasion by using the much cheaper marine grade diesel - which is what this is. Home hrade 'heating oil' is oil and diesel -- which also works just fine. It was used here after WWII as an alternative fuel and cost WAY less than commercial diesel.]
I have a donor vehicle that I'll be taking the fuel tank from and installing in my DD as an oil fuel tank. I'll run a centrifugal oil filter to recirculate the oil (direct from my local mechanic) to the tank. I'll use the spare water / sediment filter and fuel lines before an electronic gate valve tapped into the existing lines before my injection pump. Switch over is best done after a few minutes when the engine is warm. I have noticed that the vehicle is very slightly more difficult to start on ratios above 50%. It never gets below freezing here anyway - so pre heat will not be an issue for me.
Motoring at half the pump price! LOVE IT
So 14 years down the line
