Keep your engine healthy and extend your car’s lifespan with timely oil changes.

The Role of Oil Changes in Engine Longevity

Clean oil is essential for your engine to function efficiently, reducing wear, tear, and overheating. Over time, oil degrades and picks up debris, making it less efficient. Failing to change the oil can cause premature wear, overheating, and potential engine damage.

When Should You Change Your Oil?

The frequency of oil changes depends on your vehicle’s make, model, and driving habits. Here are some general recommendations:

  • For older vehicles using conventional oil: Every 3,000 to 5,000 miles
  • For newer vehicles using synthetic oil: Every 7,500 to 10,000 miles

Always consult your car’s owner manual or ask a trusted professional to determine the best schedule for your vehicle.

Warning Signs It’s Time for an Oil Change

Look for these signs to know when to change your oil.

  • Oil That Looks Dark and Gritty: Examine the dipstick: if the oil appears dark and dirty, it’s overdue for a change.
  • Loud Engine Noise: Old oil can't lubricate the engine as effectively, leading to increased engine noise.
  • Dashboard Warning Light: The oil change or check engine light is a clear indicator.
  • Exhaust Smoke: If you see blue or gray smoke, your oil may be burning, signaling a problem.
