Understanding the colour of your oil
Oil is naturally amber in colour, but over time and with use it can become darker and turn black. The colour of the oil can indicate how dirty or contaminated it is. Black oil can be caused by a variety of factors, including:
- Long time between oil changes: if you have not changed your oil in a long time, it can become dirty and contaminated, which turns it black.
- Driving habits: if you frequently drive in stop-and-go traffic or make a lot of short trips, the oil in your car can become dirty more quickly.
- Engine wear: if your engine is worn, the oil can become contaminated with metal particles, causing it to turn black.
Checking the oil
To check the oil, you will need a clean rag and the dipstick from your car's engine. Turn off the engine and wait a few minutes for the oil to settle. Then open the hood and locate the dipstick. Remove it, wipe it clean with the rag, reinsert it and pull it out again. The oil level should be between the "low" and "high" marks. If the oil is black and dirty, it's time for an oil change.
What to do if your oil is black
If you find that your oil is black, it's important to act as soon as possible:
- Get an oil change: fresh oil removes dirt and contaminants and helps keep your engine running smoothly.
- Check for leaks: if the oil level is low, it could be a sign of a leak. Check under your car for any signs of oil leakage.
- Get a professional inspection: if you're unsure what's causing the oil to turn black, take your car to a professional mechanic. They can find the cause and recommend the right course of action.
Conclusion
Black oil is not always bad, but it can be an indication that something is wrong with your engine. By understanding the colour of your oil, checking it regularly and acting when it turns black, you can keep your engine running smoothly and avoid costly repairs.
