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

How Oil Changes Impact Engine Health

Clean oil is essential for your engine to function efficiently, reducing wear, tear, and overheating. Over time, oil breaks down and collects dirt, making it less effective. Failing to change the oil can cause premature wear, overheating, and potential engine damage.

Recommended Frequency for Oil Changes

How often you need an oil change varies depending on your car's model and your driving style. As a general guideline:

  • For conventional oil in older vehicles: Oil changes should happen every 3,000 to 5,000 miles
  • For newer vehicles using synthetic oil: Every 7,500 to 10,000 miles

Refer to your owner’s manual or speak with an expert to determine the right oil change frequency for your vehicle.

Warning Signs It’s Time for an Oil Change

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

  • Dark or Dirty Oil: Examine the dipstick: if the oil appears dark and dirty, it’s overdue for a change.
  • Noisy Engine: Old oil can't lubricate the engine as effectively, leading to increased engine noise.
  • Dashboard Warning Light: A lit dashboard warning light often indicates it’s time for an oil change.
  • Visible Exhaust Smoke: If you see blue or gray smoke, your oil may be burning, signaling a problem.
