Keep your engine healthy and extend your car’s lifespan with timely 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. Failing to change the oil can cause premature wear, overheating, and potential engine damage.

How Often 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
  • Newer vehicles with synthetic oil should have oil changes 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.

Warning Signs It’s Time for an Oil Change

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

  • Dirty Oil: If the oil on the dipstick is thick and dark, it’s time to replace it.
  • Loud Engine Noise: When oil is old, it can't lubricate as well, causing the engine to sound louder.
  • Oil Change Light: The oil change or check engine light is a clear indicator.
  • Exhaust Smoke: Smoke coming from your exhaust, especially blue or gray, could indicate burning oil.

Benefits of Professional Oil Change Services

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

  • Professional Expertise: A professional technician will select the appropriate oil and ensure proper amounts.
  • Comprehensive Checks: In addition to changing the oil, professionals check various essential components.
  • Eco-Friendly Oil Disposal: Used oil is handled and disposed of safely, helping protect the environment.
