Because it has collected all the tiny particles of metal from moving parts grinding together and all kinds of burnt deposits from the pistons and cylinders. -This is why it's a good thing to do frequent oil changes.
You should change your plugs and use lucas oil....
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.
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.
increase engine oil by adding more oil
Yes, it can turn the light on for the wrong oil.
take the spark plugs out then turn the engine on
The engine will seize and lock up way before it gets hot enough to turn oil to ash.
engine oil turns black when oil mixes with the carbon from normal combustion inside the engine. this process eventually changes the viscosity of the oil and keeps it from flowing through and lubricating the motor properly.
If you are asking about the drain plug you turn it counterclockwise.
no the distrubutor drives your oil pump..
When engine oil turns gray or milkey cream color, its a sign of moisture in the oil.
Depends. mainly on how clean burning an engine is. How much carbon and blowby gets past the rings. just stick within the recommended manufacturers oil change intervals with a quality oil of api rating and you should be fine.
