The importance of regular oil changes cannot be overstated. Oil plays a crucial role in the functioning of a car’s engine, lubricating moving parts, cooling the engine, and cleaning the engine by carrying contaminants away from the surfaces. Without regular oil changes, the engine can suffer from premature wear and tear, leading to costly repairs and even complete engine failure. In this blog post, we will explore the signs that indicate a car needs an oil change, and provide a comprehensive guide on how to know if a car needs an oil change.
Signs of Low Oil Levels
One of the most obvious signs that a car needs an oil change is low oil levels. Check the oil dipstick regularly to ensure the oil level is at the recommended level. If the oil level is low, it may be a sign that the car is burning oil, which can be caused by worn piston rings, valve stem seals, or other engine components.
Another sign of low oil levels is the oil light on the dashboard. If the oil light comes on, it’s a warning that the oil level is low and needs to be checked and topped off. Ignoring this warning can lead to serious engine damage.
How to Check Oil Levels
To check oil levels, follow these steps:
- Make sure the car is parked on a level surface.
- Turn off the engine and let it sit for a few minutes to allow the oil to drain back into the oil pan.
- Locate the oil dipstick under the hood of the car. It’s usually labeled “Oil” or have an oil can symbol.
- Pull out the dipstick and wipe it clean with a lint-free rag or paper towel.
- Insert the dipstick back into the oil reservoir and pull it out again. The oil level should be between the “MIN” and “MAX” marks on the dipstick.
Signs of Dirty Oil
Another sign that a car needs an oil change is dirty oil. Dirty oil can cause engine damage, reduce fuel efficiency, and increase emissions. Here are some signs of dirty oil:
Dark or Black Color: If the oil is dark or black, it’s a sign that it’s dirty and needs to be changed.
Sludge or Debris: If you notice sludge or debris in the oil, it’s a sign that the oil is dirty and needs to be changed. (See Also: Where to Take Old Engine Oil? Proper Disposal Guide)

How to Check Oil Color
To check oil color, follow these steps:
- Use a clean, white cloth or paper towel to wipe the oil dipstick.
- Insert the dipstick back into the oil reservoir and pull it out again. The oil should be a light brown or amber color.
- If the oil is dark or black, it’s a sign that it’s dirty and needs to be changed.
Signs of Wear and Tear
Wear and tear on the engine can also indicate that a car needs an oil change. Here are some signs of wear and tear:
Increased Engine Noise: If the engine is making more noise than usual, it could be a sign of wear and tear.
Reduced Fuel Efficiency: If the car is using more fuel than usual, it could be a sign of wear and tear.
Difficulty Starting the Engine: If the engine is difficult to start, it could be a sign of wear and tear. (See Also: Where Do I Pour Oil into My Car? Easy Guide)
