Maintaining your engine’s health is easy with regular 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. As oil ages, it becomes contaminated with dirt and loses its effectiveness. If left unchecked, old oil can cause excessive wear, overheating, and severe engine problems.

When 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:

  • 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

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.

  • Oil That Looks Dark and Gritty: Check the dipstick—if the oil is dark and gritty, it’s time to change it.
  • Loud Engine Noise: When oil is old, it can't lubricate as well, causing the engine to sound louder.
  • Check Engine 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.

Why Professional Oil Changes Are Worth It

Although you can change oil yourself, professional services have distinct benefits:

  • Professional Expertise: Technicians ensure the right type and amount of oil for your vehicle.
  • Complete Inspections: Along with the oil change, technicians check filters, belts, and other key parts.
  • Proper Disposal: Used oil is handled and disposed of safely, helping protect the environment.
  • Convenient Service: Save time and avoid the mess of doing it yourself.
