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

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

  • 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

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

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

  • 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.
  • Check Engine Light: If the oil change light or check engine light appears, it’s a sign to change the oil.
  • Smoke from the Exhaust: Blue or gray smoke may mean your oil is burning, signaling an issue.

Why Choose Professional Oil Change Services?

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.
  • Thorough Inspections: In addition to changing the oil, professionals check various essential components.
