Understanding Engine Oil
Before we dive into the colours, let’s understand what engine oil does․ Engine oil lubricates moving parts, reduces friction, prevents wear, and helps keep the engine cool․ It also collects impurities, which can affect its colour over time․

Engine oil can display a range of colours, each with its own set of implications:
- Clear or Amber: Fresh oil is typically a clear amber colour․ This indicates that the oil is new and has not yet absorbed significant impurities․
- Dark Brown: As oil ages, it turns dark brown․ This is normal and signifies that the oil is doing its job by capturing dirt and contaminants․
- Black: While many may panic at the sight of black oil, it is often just a sign of heavy usage․ However, if it becomes black too quickly, it might be time for a change․
- Milky or Creamy: If your oil looks milky or creamy, it could indicate coolant contamination, which is a sign of a serious issue like a blown head gasket․
- Yellow or Green: If you see yellow or green oil, it may be a sign of excessive moisture or contamination․ This can be due to condensation or a more significant problem․
- Red: Some automatic transmission fluids are red, but if you see red in your engine oil, it could indicate a serious leak from the transmission․
