Keep your engine healthy and extend your car’s lifespan with timely oil changes.

How Oil Changes Impact Engine Health

Clean oil is essential for your engine to function efficiently, reducing wear, tear, and overheating. 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?

How often you need an oil change varies depending on your car's model and your driving style. 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

Always consult your car’s owner manual or ask a trusted professional to determine the best schedule 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: Old oil loses its ability to lubricate effectively, causing the engine to run louder.
  • Oil Change Light: A lit dashboard warning light often indicates it’s time for an oil change.
  • Visible 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.
