How often should I change my car's oil?

The traditional recommendation to change your oil every 3,000 miles is now considered outdated [2, 3].

Advancements in both engine technology and the quality of modern oil blends mean that most engines can now go much longer between changes [3]. Today, it is common for manufacturers to recommend intervals between 5,000 and 7,500 miles [3].

However, there are a few important things to keep in mind:

• Follow your manual: Always check your owner’s manual or the manufacturer's official maintenance schedule first. They know the specific needs of your engine best.
• Time matters too: Even if you don't drive many miles, most manufacturers do not recommend leaving the same oil in your engine for more than a year [1]. Oil can degrade over time, regardless of how much you drive.
• Driving conditions: If you frequently drive in "severe" conditions—such as stop-and-go city traffic, extreme heat, or very short trips where the engine doesn't fully warm up—your specific maintenance schedule may suggest more frequent intervals.

Ultimately, the 3,000-mile rule is a myth [1, 2], but staying consistent with your car's specific manual will keep your engine running smoothly for longer.
