Removing Burnt Carbon from Used Oil

In summary, the person is looking for advice on how to get burnt carbon out of used oil. They have tried all they can think of, but still can't get it all out. There is a bleach or something they can use, but it takes too long. They have also tried using hydraulick oil, but it doesn't work as well as removing the burnt carbon.

You can extract it with an aqueous solution of sodium silicate (42 baume) diluted somewhat. The carbon will go out with the water.

hi thank you will try the sodium out,
what about used hydraulick oil will it work the same or is their something else that will clean it

Just removing the "burnt carbon" will not make the oil suitable for use in an engine again.

yes i know this i do make biodiesel , and have a centralfuge and all the filters but the rest of thining it out for use hydraulick oil at a 50 50 or running by extra heater no problem but still can't get the black or brown stuff out not even at over 5000 r.p.m i am an engineer so i made my own machines up but i am no Genius nor perfect at this cleaning oil lol

sodium silicate may do the job but at the moment i am still trying to get some without any luck. I have an endles suppley of hydraulick oil to keep me going for a long time so i do want to waste it. so if anyone out their know were i can get some sodium silicate in derbyshire please let me know
thanks

Pottery shops usually have some around to make 'slip'. It is sometimes called 'egg preserver' silicate.

Hydraulic oils have lots of detergents and high pressure additives. I wouldn't try extracting it with any caustic (unless you like mayonnaise...). Some hydraulics oils are ester based rather than light petroleum oil based and would react with sodium silicate.
