Oil plays a vital role in lubricating the engine’s moving parts and keeping them cool, clean, and protected. Over time, oil breaks down and becomes less effective at performing its job. This degradation can lead to engine damage and potentially cause your car to stall.
Alert Systems In Modern Vehicles
Modern vehicles are equipped with sophisticated alert systems that monitor various aspects of the car’s performance. These systems have sensors that can detect the condition of the oil and alert the driver when it is time for an oil change. Typically, a maintenance light or warning message will illuminate on the dashboard to indicate that the oil change is due. By paying attention to these alerts and promptly scheduling an oil change, you can prevent issues such as stalling caused by bad oil.
Oil Change Frequency For Older Vehicles
If you have an older vehicle, it may not have the advanced alert systems found in modern cars. In these cases, it is generally recommended to change the oil every 3-6 months, depending on your driving habits and the type of oil you use. Frequent oil changes are particularly important for older vehicles because the engine components may have more wear and tear. Neglecting to change the oil within the specified time frame can result in oil degradation and the potential for stalling or seizing of the engine.
Sign 1: Low Oil Level
One of the signs that your vehicle is due for an oil change is a low oil level. You can check your oil level by using the dipstick, which is typically located near the engine. If the oil level is significantly below the recommended level, it indicates that your car is running low on oil.
Insufficient oil can lead to friction and heat buildup in the engine, potentially causing it to stall unexpectedly.
- Low oil level is a sign that your vehicle needs an oil change.
- Use the dipstick to check your oil level.
- Insufficient oil can cause friction and heat buildup in the engine.
- This can lead to the engine stalling unexpectedly.
