5 Warning Signs It’s Time to Change Your Engine Oil and How to Properly Maintain It
Engine oil is a crucial aspect of vehicle maintenance, ensuring that the engine runs efficiently and prolonging the car’s lifespan. Here are the signs that indicate it’s time to change your engine oil:
Frequent Fueling, Increased Fuel Consumption
If you notice that you need to refuel more often than usual or the engine seems to be consuming more fuel, it could be a sign that the engine is under stress or there is incomplete combustion. This may be caused by degraded engine oil that is no longer able to lubricate the engine parts properly.
Exhaust Pipe Emitting Black Smoke
Recommendation: Regularly check the engine oil level to ensure it is not below the recommended level. Low oil levels can cause the engine to wear out.
Exhaust Pipe Emitting Black Smoke
Black smoke from the exhaust often indicates incomplete combustion, which can be caused by several factors, such as degraded engine oil that cannot lubricate properly. This causes the engine to work harder, leading to incomplete fuel combustion. Using low-quality engine oil or an unsuitable brand can also contribute to black smoke.
Recommendation: If black smoke continues to come from the exhaust, take your car for a check-up on the combustion system and engine oil. If the oil is found to be degraded or ineffective, it should be replaced immediately.
Strange Noises When Starting the Engine
Cause: When starting the engine, the engine oil’s job is to lubricate various engine parts, such as the pistons, shafts, and moving components. If the engine oil is degraded or ineffective, the lubrication will be insufficient, resulting in strange or knocking noises, which may be caused by friction between internal engine parts.
Engine Oil Becomes Thick and Black (Normally Light Brown)
As the engine is used, the engine oil gradually degrades due to exposure to heat and the engine’s operation. Degraded oil absorbs contaminants like carbon, dust, and metal particles from worn engine parts. This causes the oil to turn thick and black, similar to tar. Oil that has become thick and dark cannot lubricate the engine effectively and may cause wear on engine parts.
Maintenance and Oil Change:
Check Oil Levels and Color: It’s recommended to check the engine oil level every 1,000 kilometers.
Change Oil Regularly: Follow the vehicle manufacturer’s recommendations for oil changes, typically every 5,000-10,000 kilometers.
Use Quality Oil: Choose high-quality oil that matches the manufacturer’s recommendations for optimal lubrication performance.
Monitor Engine Performance: If the oil has absorbed too many contaminants and the engine begins making strange noises or consuming more fuel, take the car to a service center to check the lubrication system for potential issues.
Unusual Vibration and Rough Idling
When a car vibrates excessively and idles roughly, there could be several causes for this issue. One common cause is the deterioration of the engine oil, or the oil failing to lubricate effectively. This results in the engine operating inefficiently, causing more vibrations and rough idling. If you experience this, it’s important to check the engine oil and replace it if necessary to restore smooth engine operation.
When is the right time to change engine oil? 🤔
Changing engine oil is essential for maintaining your car’s engine. Generally, engine oil should be changed based on the mileage or time intervals recommended by the vehicle manufacturer. Typically, this is every 5,000 – 10,000 kilometers.
Tip: ✅ Think of it like going to the doctor for an annual check-up. Your car needs regular care too! Use ACDelco engine oil to help protect and preserve your engine’s performance.
