Regular oil changes are key to ensuring your engine runs smoothly and lasts longer.

How Oil Changes Impact Engine Health

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

The frequency of oil changes depends on your vehicle’s make, model, and driving habits. Generally speaking, the following guidelines apply:

  • Older cars using conventional oil: Change every 3,000 to 5,000 miles
  • Newer vehicles with synthetic oil should have oil changes 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

These are the signs your car is ready for an oil change:

  • Dirty Oil: Check the dipstick—if the oil is dark and gritty, it’s time to change it.
  • Engine Running Loud: When oil is old, it can't lubricate as well, causing the engine to sound louder.
  • Dashboard Warning Light: If the oil change light or check engine light appears, it’s a sign to change the oil.
  • Smoke from the Exhaust: Blue or gray smoke may mean your oil is burning, signaling an issue.

Benefits of Professional Oil Change Services

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

  • Skilled Technicians: A professional technician will select the appropriate oil and ensure proper amounts.
  • Complete Inspections: Professionals inspect filters, belts, and other components during the service.
  • Responsible Disposal: Used oil is disposed of responsibly, reducing environmental harm.
  • Convenience: Let the experts handle it, saving you time and avoiding the mess.
