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. Without regular oil changes, this can lead to increased wear and tear, overheating, and even engine failure.

Recommended Frequency for Oil Changes

How often you need an oil change varies depending on your car's model and your driving style. As a general guideline:

  • 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

Check your owner’s manual or consult a mechanic to figure out the ideal schedule for your car.

How to Know When It’s Time for an Oil Change

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

  • Dark or Dirty Oil: Examine the dipstick: if the oil appears dark and dirty, it’s overdue for a change.
  • Engine Running Loud: Old oil can't lubricate the engine as effectively, leading to increased engine noise.
  • Dashboard Warning Light: The oil change or check engine light is a clear indicator.
  • Smoke from the Exhaust: Smoke coming from your exhaust, especially blue or gray, could indicate burning oil.
