It's typical for new or clean motor oil to be light amber in color. When you see light yellow or amber oil in your dipstick, your oil is clean and good to go for another 3000-5000 miles without changing.

2. Dark Brown or Black

Dark oil often indicates that it has cycled throughout your engine too frequently and needs to be changed. It may be expected for engine oil to turn dark brown or black, or there may be a problem.

Remember that thin engine oil that is deeper in color does not necessarily mean that the oil is unclean. But if it is thick and dark, it may indicate soot build-up due to dirt or dust contaminants exposure and needs to be replaced.

Using oil with numerous chemicals and additives of different engine oil brands may also produce black crude.

3. Milky or Cream

If the oil seems milky and foamy, it indicates an oil issue with moisture. Typically head gasket leak that causes the cream-colored oil usually allows coolant to seep into the oil.

Some common signs of a leaking head gasket include:

  • Leaking coolant under your car
  • Low coolant level 
  • White smoke from the exhaust

If you don’t observe the other symptoms above, there is a slight chance that the creamy oil isn’t a head gasket rupture. Therefore, don’t put off getting the issue fixed, or you risk accruing even higher repair costs. 

In some cases, if water accidentally contaminates the oil, you may change the oil, and the problem ought to go away.

4. Rust

The engine oil may change color to rust if your car is older or you reside in an overly humid area. This may result to condensation accumulation and cause rusting on the surface of the dipstick, giving the oil a rusty appearance. 

In addition, there’s a risk of a flaw causing some automatic transmission fluid to seep into the engine. The combination may then have a rusty appearance. But it should be a warning that you must immediately take the car to the technician.

Note that some engine oils are reddish brown in color when they are new. Out-of-the-bottle, conventional engine oils are a red-brown amber color.
