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

How Regular Oil Changes Benefit Your Engine

Oil is crucial for your engine to run smoothly, providing lubrication and controlling the engine’s temperature. As oil ages, it becomes contaminated with dirt and loses its effectiveness. Failing to change the oil can cause premature wear, overheating, and potential engine damage.

Recommended Frequency for Oil Changes

Oil change intervals are influenced by factors like your car's make, model, and driving conditions. As a general guideline:

  • 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

Always consult your car’s owner manual or ask a trusted professional to determine the best schedule for your vehicle.

Signs Your Car Needs an Oil Change

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

  • Dirty Oil: Check the dipstick—if the oil is dark and gritty, it’s time to change it.
  • Engine Running Loud: When oil is old, it can't lubricate as well, causing the engine to sound louder.
  • Oil Change Light: If the oil change light or check engine light appears, it’s a sign to change the oil.
  • Exhaust Smoke: Blue or gray smoke may mean your oil is burning, signaling an issue.

Why Professional Oil Changes Are Worth It

While DIY oil changes are an option, professional services offer significant advantages:

  • Skilled Technicians: A professional technician will select the appropriate oil and ensure proper amounts.
  • Thorough Inspections: Along with the oil change, technicians check filters, belts, and other key parts.
  • Responsible Disposal: Used oil is handled and disposed of safely, helping protect the environment.
  • Save Time: Save time and avoid the mess of doing it yourself.
