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. Over time, oil breaks down and collects dirt, making it less effective. Failing to change the oil can cause premature wear, overheating, and potential engine damage.

Recommended Frequency for Oil Changes

How often you need an oil change varies depending on your car's model and your driving style. Generally speaking, the following guidelines apply:

  • Older cars using conventional oil: Change every 3,000 to 5,000 miles
  • Newer vehicles with synthetic oil should have oil changes 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.

Warning Signs 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: Old oil loses its ability to lubricate effectively, causing the engine to run louder.
  • Oil Change Light: The oil change or check engine light is a clear indicator.
  • Exhaust Smoke: 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:

  • Professional Expertise: Technicians ensure the right type and amount of oil for your vehicle.
  • Comprehensive Checks: In addition to changing the oil, professionals check various essential components.
  • Proper Disposal: Technicians dispose of used oil properly, minimizing environmental impact.
