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

The Role of Oil Changes in Engine Longevity

Your car’s engine relies on clean oil to lubricate its moving parts, reduce friction, and regulate temperature. 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?

How often you need an oil change varies depending on your car's model and your driving style. Here are some general recommendations:

  • Older cars using conventional oil: Change every 3,000 to 5,000 miles
  • For newer vehicles using synthetic oil: Every 7,500 to 10,000 miles

Check your owner’s manual or consult a mechanic to figure out the ideal schedule for your car.

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.
  • Engine Running Loud: Old oil can't lubricate the engine as effectively, leading to increased engine noise.
  • Oil Change Light: A lit dashboard warning light often indicates it’s time for an oil change.
  • Exhaust Smoke: Blue or gray smoke may mean your oil is burning, signaling an issue.

Why Professional Oil Changes Are Worth It

While you could change your oil at home, there are several reasons to leave it to the professionals:

  • Professional Expertise: Technicians ensure the right type and amount of oil for your vehicle.
  • Thorough Inspections: In addition to changing the oil, professionals check various essential components.
  • Eco-Friendly Oil Disposal: Used oil is disposed of responsibly, reducing environmental harm.
  • Convenient Service: Let the experts handle it, saving you time and avoiding the mess.
