The Importance of Engine Oil Color
Engine oil is a complex mixture of various chemicals and additives that work together to keep your engine running smoothly. The color of the oil is a result of the chemical composition and the presence of contaminants. The color of the oil can indicate the level of wear and tear on your engine, as well as the presence of contaminants such as dirt, debris, and metal shavings.
When it comes to engine oil color, there are several different shades to be aware of. The most common colors are:
- Light brown or amber: This is the normal color of new engine oil and indicates that the oil is clean and free of contaminants.
- Dark brown or black: This indicates that the oil has broken down and is no longer effective at lubricating the engine.
- Red or pink: This is a sign of coolant contamination and can be a serious problem if left unchecked.
- Blue or green: This is a sign of engine oil contamination and can be a sign of a serious problem.
How to Check the Color of Your Engine Oil
