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?

Oil change intervals are influenced by factors like your car's make, model, and driving conditions. Here are some general recommendations:

  • For older vehicles using conventional oil: Every 3,000 to 5,000 miles
  • For newer vehicles using 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.

Warning Signs 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.
  • Check Engine Light: If the oil change light or check engine light appears, it’s a sign to change the oil.
  • Exhaust Smoke: If you see blue or gray smoke, your oil may be burning, signaling a problem.

Benefits of Professional Oil Change Services

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

  • Expert Handling: A professional technician will select the appropriate oil and ensure proper amounts.
  • Thorough Inspections: Along with the oil change, technicians check filters, belts, and other key parts.
  • Proper Disposal: Used oil is disposed of responsibly, reducing environmental harm.
  • Convenient Service: Save time and avoid the mess of doing it yourself.
