Maintaining your engine’s health is easy with regular oil changes.

How Oil Changes Impact Engine Health

Oil is crucial for your engine to run smoothly, providing lubrication and controlling the engine’s temperature. Over time, oil degrades and picks up debris, making it less efficient. Failing to change the oil can cause premature wear, overheating, and potential engine damage.

When Should You Change Your Oil?

The frequency of oil changes depends on your vehicle’s make, model, and driving habits. Generally speaking, the following guidelines apply:

  • For older vehicles using conventional oil: Every 3,000 to 5,000 miles
  • For newer vehicles using synthetic oil: Every 7,500 to 10,000 miles

Refer to your owner’s manual or speak with an expert to determine the right oil change frequency for your vehicle.

Warning Signs It’s Time for an Oil Change

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

  • Oil That Looks Dark and Gritty: 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.
  • Check Engine Light: If the oil change light or check engine light appears, it’s a sign to change the oil.
  • Exhaust Smoke: If you see blue or gray smoke, your oil may be burning, signaling a problem.

Why Professional Oil Changes Are Worth It

While you could change your oil at home, there are several reasons to leave it to the professionals:

  • Professional Expertise: Technicians ensure the right type and amount of oil for your vehicle.
  • Complete Inspections: Professionals inspect filters, belts, and other components during the service.
  • Responsible Disposal: Technicians dispose of used oil properly, minimizing environmental impact.
  • Convenient Service: Save time and avoid the mess of doing it yourself.
