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

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. 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:

  • 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.

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

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

  • Oil That Looks Dark and Gritty: 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.
  • Dashboard Warning Light: A lit dashboard warning light often indicates it’s time for an oil change.
  • Visible Exhaust Smoke: If you see blue or gray smoke, your oil may be burning, signaling a problem.

Why Professional Oil Changes Are Worth It

Although you can change oil yourself, professional services have distinct benefits:

  • Expert Handling: 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.
  • Eco-Friendly Oil Disposal: Technicians dispose of used oil properly, minimizing environmental impact.
  • Save Time: Save time and avoid the mess of doing it yourself.
