The sound of a car is a crucial aspect of its overall performance, and it can often indicate potential problems with the vehicle’s engine. One of the most common issues that can cause a car to make unusual sounds is low oil levels or oil-related problems. In this blog post, we will explore the topic of “How Does a Car Sound When it Needs Oil?” and provide a comprehensive guide to help car owners identify and address potential oil-related issues.
Regular oil changes are essential for the longevity and performance of a car’s engine. Engine oil lubricates the moving parts of the engine, prevents corrosion, and keeps the engine clean. When the oil level drops or the oil becomes dirty, it can cause the engine to produce unusual sounds. Ignoring these sounds can lead to serious engine damage, which can result in costly repairs or even render the car inoperable.
As a car owner, it’s essential to be aware of the sounds your car makes and to take prompt action if you notice any unusual noises. In this blog post, we will discuss the common sounds a car makes when it needs oil, the causes of these sounds, and the steps you can take to address the issue.

Common Sounds a Car Makes When it Needs Oil
When a car needs oil, it can produce a range of unusual sounds, including:
- Whining or whirring noises
- Grinding or screeching sounds
- Clunking or clunking noises
- Knocking or tapping sounds
- Whistling or hissing noises
These sounds can occur due to various reasons, including low oil levels, dirty oil, or worn-out engine components. In the following sections, we will discuss each of these sounds in detail and provide tips on how to identify and address the issue.
Whining or Whirring Noises
Whining or whirring noises are often caused by low oil levels or dirty oil. When the oil level is low, the engine’s moving parts can rub against each other, producing a whining or whirring sound. Similarly, dirty oil can cause the engine’s components to wear out, leading to a whining or whirring noise.
To identify the cause of the whining or whirring noise, check the oil level and condition. If the oil level is low, add the recommended type and amount of oil. If the oil is dirty, consider changing it with a new oil filter.
Grinding or Screeching Sounds
Grinding or screeching sounds are often caused by worn-out engine components, such as the timing belt or serpentine belt. When these components wear out, they can produce a grinding or screeching sound.
To identify the cause of the grinding or screeching noise, inspect the timing belt and serpentine belt for signs of wear. If you find any damage, replace the belt with a new one.
Clunking or Clunking Noises
Clunking or clunking noises are often caused by loose or worn-out engine mounts. When the engine mounts wear out, they can cause the engine to move around, producing a clunking or clunking noise.
To identify the cause of the clunking or clunking noise, inspect the engine mounts for signs of wear. If you find any damage, replace the mounts with new ones. (See Also: Why Is There A Puddle Of Oil Under My Car? – Find The Cause)
Knocking or Tapping Sounds
Knocking or tapping sounds are often caused by low compression in the engine cylinders. When the compression is low, the engine can produce a knocking or tapping sound.
To identify the cause of the knocking or tapping noise, check the engine compression. If the compression is low, consider taking the car to a mechanic for further diagnosis and repair.
Whistling or Hissing Noises
Whistling or hissing noises are often caused by a leak in the engine’s cooling system. When the cooling system leaks, it can produce a whistling or hissing sound.
To identify the cause of the whistling or hissing noise, inspect the cooling system for signs of leaks. If you find any leaks, repair or replace the damaged components.
Causes of Unusual Sounds in a Car
Unusual sounds in a car can be caused by a range of factors, including:
- Low oil levels
- Dirty oil
- Worn-out engine components
- Loose or worn-out engine mounts
- Low compression in the engine cylinders
- Leaks in the cooling system
- Worn-out or damaged timing belt or serpentine belt
These causes can be further broken down into the following subcategories:
Engine Oil-Related Issues
Engine oil-related issues are a common cause of unusual sounds in a car. These issues can include:
- Low oil levels
- Dirty oil
- Worn-out engine components
To address engine oil-related issues, check the oil level and condition regularly. Add the recommended type and amount of oil if the level is low, and consider changing the oil with a new oil filter if it’s dirty.
Engine Component-Related Issues
Engine component-related issues are another common cause of unusual sounds in a car. These issues can include: (See Also: How to Get Motor Oil Off Concrete? Easy Solutions)

Cooling System-Related Issues
Cooling system-related issues are a common cause of unusual sounds in a car. These issues can include:
- Leaks in the cooling system
To address cooling system-related issues, inspect the cooling system for signs of leaks. Repair or replace the damaged components if you find any leaks.
Steps to Take When Your Car Makes Unusual Sounds
When your car makes unusual sounds, it’s essential to take prompt action to address the issue. Here are the steps you can take:
Check the Oil Level and Condition
Check the oil level and condition regularly to ensure that it’s at the recommended level and not dirty. Add the recommended type and amount of oil if the level is low, and consider changing the oil with a new oil filter if it’s dirty.
Inspect the Timing Belt and Serpentine Belt
Inspect the timing belt and serpentine belt for signs of wear. Replace the belt with a new one if you find any damage.
Inspect the Engine Mounts
Inspect the engine mounts for signs of wear. Replace the mounts with new ones if necessary.
Check the Engine Compression
Check the engine compression to ensure that it’s within the recommended range. Consider taking the car to a mechanic for further diagnosis and repair if the compression is low.
Inspect the Cooling System
Inspect the cooling system for signs of leaks. Repair or replace the damaged components if you find any leaks.
