Oil turns back due to the cleaning agents in modern quality oil. Generally the newer oils clean your engine and pick up little bits of sludge, dirt, garbage, etc and it contaminates the oil. This is why you run your engine for 5-10 mins before doing a oil change so your oil can pick up junk and it drains right out! Also, as oil breaks down it normally turns a darker color.

Why does your 96 Saturn oil turn black?

All oil turns black over time. Most of the black comes from small particles that are trapped in the oil. Also, carbon from the incomplete combustion of gasoline is held in the oil. It is impossible to get all of the oil out of an engine unless the engine is taken apart and cleaned. This left over "dirty" oil can cause new oil to darken.


What is the cause the engine oil become dirty and changing colours?

Oil contains detergents that clean your engine and suspend soot, deposits, & dirt in the oil. The air and oil filters remove most of the larger particles but some get in the engine and stay suspended in the oil which causes it to turn black. Oil is not only a lubricant and helps cool the engine, but it also keeps the engine clean.
