For any vehicle to operate efficiently and effectively, regular maintenance is non-negotiable. Among the most critical routine services is the oil change, a simple procedure that can significantly impact your car's performance and longevity. In this post, we'll explore the top five signs that indicate your car needs a professional oil change.

Sign #1: The Mileage Indicator

One of the most straightforward indicators that it's time for an oil change is your car's mileage. Most manufacturers recommend an oil change every 5,000 to 7,500 miles, but this can vary based on your vehicle's make, model, and the type of oil used.

Sign #2: Engine Noise and Knocking

When engine oil becomes old or low, it can lead to increased engine noise or knocking. This is because the oil is no longer providing the necessary lubrication to engine components, resulting in metal-on-metal contact.

Sign #3: Dirty or Dark Oil

Clean oil is typically a light amber color. Over time, it gets contaminated with particles and by-products of combustion, turning it darker. Checking your oil regularly can help you identify when it has become too dirty and needs changing.

Sign #4: Oil Change or Check Engine Light

The appearance of an oil change reminder or check engine light on your dashboard is a clear signal that your vehicle needs attention. While it could indicate various issues, it often means that an oil change is overdue.

Sign #5: Exhaust Smoke and Odd Smells

Excessive exhaust smoke or the smell of burning oil could indicate an oil leak or that the oil is contaminated and burning within the engine. These are serious signs that your vehicle needs a professional oil change immediately.
