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. Without regular oil changes, this can lead to increased wear and tear, overheating, and even engine failure.

When Should You Change Your Oil?

Oil change intervals are influenced by factors like your car's make, model, and driving conditions. Generally speaking, the following guidelines apply:

  • Older cars using conventional oil: Change every 3,000 to 5,000 miles
  • For modern cars with 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.

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.
  • Noisy Engine: When oil is old, it can't lubricate as well, causing the engine to sound louder.
  • Dashboard Warning Light: A lit dashboard warning light often indicates it’s time for an oil change.
  • Smoke from the Exhaust: If you see blue or gray smoke, your oil may be burning, signaling a problem.

Why Professional Oil Changes Are Worth It

While DIY oil changes are an option, professional services offer significant advantages:

  • Expert Handling: Technicians ensure the right type and amount of oil for your vehicle.
  • Comprehensive Checks: Professionals inspect filters, belts, and other components during the service.
  • Responsible Disposal: Used oil is disposed of responsibly, reducing environmental harm.
  • Convenience: Skip the hassle of a DIY oil change and enjoy professional service.
