Regular oil changes are key to ensuring your engine runs smoothly and lasts longer.

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?

How often you need an oil change varies depending on your car's model and your driving style. Here are some general recommendations:

  • 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

Pay attention to these warning signs that indicate it’s time for an oil change:

  • Dark or Dirty Oil: Check the dipstick—if the oil is dark and gritty, it’s time to change it.
  • Engine Running Loud: Old oil can't lubricate the engine as effectively, leading to increased engine noise.
  • Dashboard Warning Light: A lit dashboard warning light often indicates it’s time for an oil change.
  • Smoke from the Exhaust: 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:

  • Skilled Technicians: Technicians ensure the right type and amount of oil for your vehicle.
  • Comprehensive Checks: Along with the oil change, technicians check filters, belts, and other key parts.
  • Responsible Disposal: Technicians dispose of used oil properly, minimizing environmental impact.
  • Convenience: Skip the hassle of a DIY oil change and enjoy professional service.
