Maintaining your engine’s health is easy with regular oil changes.

The Role of Oil Changes in Engine Longevity

Oil is crucial for your engine to run smoothly, providing lubrication and controlling the engine’s temperature. As oil ages, it becomes contaminated with dirt and loses its effectiveness. Without regular oil changes, this can lead to increased wear and tear, overheating, and even engine failure.

How Often Should You Change Your Oil?

How often you need an oil change varies depending on your car's model and your driving style. Generally speaking, the following guidelines apply:

  • 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

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

How to Know When 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 loses its ability to lubricate effectively, causing the engine to run louder.
  • Check Engine 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.

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

  • Professional Expertise: A professional technician will select the appropriate oil and ensure proper amounts.
  • Thorough Inspections: In addition to changing the oil, professionals check various essential components.
