Hi..
When you are servicing your vehicle, have you see the mechanic take a small vacuum pump to suck the oil engine? Where they actually place the used lubricant oil? Is that place in a drum, or dump it easily? All that question or more should play in our mind..
If you search on wikipedia, it mention about the function of lubricant oil and it can be summarize as follow:
1) Is an oil used for lubrication of various internal combustion engine
2) Motor oil also cleans
3) inhibits corrosion
4) improves sealing
5)Cool the engine by carrying heat away from the moving parts.
Most of engine oil are produce from derived petroleum which contain of hydrocarbon.
Us EPA has define engine oil must be managed under hazardous waste when it is disposed of. So that, by spilling it to the environment, it can pose threat to us.
Have you heard about additives that have been used to the used engine oil? For your knowledge, the additives is meant for changing the value of it viscosity so that, it suit to standard lubricating oil. The value that determine by SAE for good lubricating oil is between 40 to 400 according to their Viscosity Index.
By inventing additives for lubricant oil, we should make money and actually we are saving our environment.
But if no additives will used, we will damage our engine, and damage our air by releasing excessive smoke, and you know what is inside the smoke.
