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

How Oil Changes Impact Engine Health

Your car’s engine relies on clean oil to lubricate its moving parts, reduce friction, and regulate temperature. Over time, oil breaks down and collects dirt, making it less effective. Without regular oil changes, this can lead to increased wear and tear, overheating, and even engine failure.

When Should You Change Your Oil?

The frequency of oil changes depends on your vehicle’s make, model, and driving habits. As a general guideline:

  • 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

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

Signs Your Car Needs an Oil Change

These are the signs your car is ready for an oil change:

  • Oil That Looks Dark and Gritty: If the oil on the dipstick is thick and dark, it’s time to replace it.
  • Loud Engine Noise: When oil is old, it can't lubricate as well, causing the engine to sound louder.
  • Oil Change Light: A lit dashboard warning light often indicates it’s time for an oil change.
  • Exhaust Smoke: Smoke coming from your exhaust, especially blue or gray, could indicate burning oil.

Why Professional Oil Changes Are Worth It

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

  • Professional Expertise: A professional technician will select the appropriate oil and ensure proper amounts.
  • Complete Inspections: In addition to changing the oil, professionals check various essential components.
  • Proper Disposal: Technicians dispose of used oil properly, minimizing environmental impact.
  • Convenient Service: Let the experts handle it, saving you time and avoiding the mess.
