Ever turn down the radio to listen to your car, wondering if that faint, new ticking is normal or an early warning? While the 3,000-mile sticker on the windshield is a familiar reminder, most vehicles signal their needs long before that. Learning to spot these subtle cues is key to keeping your car running, especially since data from Hedges & Company shows the average car on U.S. roads is now a record 12.6 years old. For drivers in Lafayette and the surrounding parishes, catching these signs early can mean the difference between a simple service at a trusted local mechanic like In & Out Oil Change and a major engine repair.
1. Increased Engine Noise or a Knocking Sound
An audible change in your engine's performance is one of the clearest signs you need an oil change. Fresh oil creates a protective cushion between moving engine parts, keeping them from grinding together. But as oil gets old, it thins out and stops lubricating as well as it should. You might start to hear a louder engine roar, a new ticking, or even a knocking sound that gets faster as you accelerate. That noise is the sound of friction, a warning that internal parts are wearing down. If you ignore it, you risk serious and premature engine failure. A certified technician can quickly diagnose whether old oil is the problem.
