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

How Regular Oil Changes Benefit Your Engine

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. Failing to change the oil can cause premature wear, overheating, and potential engine damage.

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. Here are some general recommendations:

  • For older vehicles using conventional oil: 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.

Warning Signs It’s Time for an Oil Change

Look for these signs to know when to change your oil.

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

Why Professional Oil Changes Are Worth It

While DIY oil changes are an option, professional services offer significant advantages:

  • Expert Handling: 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.
  • Responsible Disposal: Used oil is disposed of responsibly, reducing environmental harm.
  • Save Time: Save time and avoid the mess of doing it yourself.
