Used Car Engine Oil: What Mechanics Do & How to Filter

[RKD89]

I was wondering what do mechanics do with used car engine oils( lubricants)?

Like are they recyclable .....

I know how water and Oil can be separated , but how does one filter dust and other particles from oils....


thanks in advance

I think we covered this topic last year...I save it..along with the old race tires.then on Earth Day i have a huge bon fire and toss them in..to celebrate Gaia..
heres a tip for you..don't throw old batteries in the fire..I usually take them to the river near by..

ok seriously. most repair shops save the oil and antifeeze. the recycle people pick this up, and old iron brake rotors and the like and recycle it. In most all the states, it is not legal to dump this and any spills over 5 gallons must be reported to the EPA. You do not have to separate the ainti freeze, atf from motor oil.

Alot of shops have waste oil heaters for use in the colder months.

dunno about the mechanics but i know that every car with an internal combustion engine has an oil filter which is usually a mesh of some material(paper?) that sorts out the relatively small pieces of steel in the oil, when it clogs up you need to change the filter and usually you change the oil as well.

now I am sure that recycling plants filter down the used oil a few times with this system until its good to be used again. i also think that the science of nano materials has contributed a lot to this process, after all a diesel engine can just about burn any type of oil out there, probably even distilled lubricant oil, so i guess its certainly called upon.

I know people who burn waste oil in diesel engines without distillation. They just filter it before adding it to the tank. It is kept dilluted enough to keep the viscosity low enough.
