Top Signs Your Car Needs an Oil Change in Morton Grove, IL

July 19, 2024

Maintaining your vehicle’s health is crucial for a smooth and safe driving experience. At ProAuto in Morton Grove, IL, we understand the importance of regular oil changes in ensuring your car runs efficiently and prolonging its lifespan. In this blog post, we will explore the top signs indicating that your car needs an oil change, helping you stay ahead of potential issues and keep your vehicle in optimal condition.


1. Dashboard Oil Light

One of the most obvious signs that your car needs an oil change is the illumination of the oil light on your dashboard. This light is triggered by a sensor that monitors the oil level and pressure in your engine. If this light comes on, it’s a clear indication that your oil level is low or the oil pressure is inadequate. Ignoring this warning can lead to severe engine damage. At ProAuto in Morton Grove, IL, we recommend addressing this issue promptly to avoid costly repairs.


2. Engine Noise and Knocking

Oil plays a crucial role in lubricating the engine’s moving parts. When the oil is old or contaminated, it loses its effectiveness, leading to increased friction. This friction can cause unusual engine noises, such as knocking or ticking sounds. If you notice these sounds while driving, it’s a sign that your oil needs changing. At ProAuto, our experienced technicians can provide a thorough oil change service to restore your engine’s smooth operation.


3. Exhaust Smoke

While some vapor from the exhaust is normal, noticeable smoke can be a red flag. Dark, thick smoke from your exhaust could indicate that the oil in your engine is too old and has turned into sludge. This sludge can clog your engine and reduce its performance. If you observe excessive exhaust smoke, visit ProAuto in Morton Grove, IL, for a comprehensive oil change and engine check-up.


4. Oil Smell Inside the Car

If you detect the smell of oil inside your car, it could mean there’s an oil leak or that the oil is burning due to high engine temperatures. This is not only a sign that you need an oil change but also that your vehicle requires immediate attention to prevent further damage. Our team at ProAuto can quickly diagnose and fix oil leaks, ensuring your car remains safe to drive.


5. Dark and Dirty Oil

New, clean oil is typically amber in color and translucent. Over time, oil collects dirt, debris, and contaminants, turning it dark and opaque. You can check the oil’s condition by using the dipstick. If the oil appears dirty, it’s time for a change. At ProAuto, we provide top-quality oil change services, using high-grade oil that keeps your engine clean and efficient.


6. Decreased Fuel Economy

Old, dirty oil can cause your engine to work harder, leading to decreased fuel efficiency. If you notice that you’re filling up your gas tank more frequently than usual, it could be due to the condition of your oil. Regular oil changes at ProAuto in Morton Grove, IL, can improve your car’s fuel economy, saving you money at the pump.


7. Excessive Mileage

Every vehicle has a recommended oil change interval, typically outlined in the owner’s manual. For most cars, this is between 3,000 and 5,000 miles, though some newer models can go longer. If you’ve driven more miles than recommended without an oil change, it’s time to schedule one. At ProAuto, we can help you keep track of your oil change schedule and ensure your car receives timely maintenance.


Regular oil changes are essential for maintaining your vehicle’s performance and longevity. Recognizing the signs that your car needs an oil change can prevent serious engine problems and keep your car running smoothly. At ProAuto in Morton Grove, IL, we are committed to providing exceptional oil change services, ensuring your vehicle remains in top condition.
