Why, When, and How To Do An Oil Change

January 8, 2025

Did you know that skipping routine maintenance, like oil changes, leads to 44% of vehicle breakdowns according to AAA? 


Maintaining your car's engine isn't just about performance—it's about longevity and efficiency. Regular oil changes are a simple yet powerful way to keep your vehicle running smoothly.


Here's why:


Lubrication: The Secret to a Smooth Engine

  • Oil reduces friction between engine parts, preventing wear and tear.
  • Without proper lubrication, components grind against each other, leading to damage.

Protecting Your Investment: Prevent Engine Damage

  • Fresh oil is a shield for your engine.
  • Neglecting oil changes can cause parts to overheat or break, meaning hefty repair bills.

Debris Detox: Keeping Your Engine Clean

  • Over time, oil collects dirt, debris, and tiny metal particles.
  • Regular oil changes act as a detox, flushing out harmful contaminants and provide peak performance.

Heat Control: Regulate Engine Temperature

  • Fresh oil helps carry heat away from critical engine components.
  • Consistent oil changes can prevent overheating and extend your car’s lifespan.


When Should You Change Your Oil?


Follow Your Manufacturer’s Recommendations

Check your owner’s manual for specific guidelines. Most vehicles require an oil change every 5,000–7,500 miles.


Adjust for Driving Conditions

Drive in harsh climates? Sit in heavy traffic? Frequently tow or haul? These conditions wear oil faster—consider more frequent changes.


Watch for Warning Signs

  • Low or dirty oil on the dipstick.
  • Dashboard oil indicators lighting up.
  • Unusual engine noises or reduced performance.


Choosing the Right Oil for Your Car


Synthetic vs. Conventional Oils

  • Synthetic Oil: Ideal for extreme conditions and longer-lasting.
  • Conventional Oil: Budget-friendly and great for older vehicles.


Viscosity Grades

  • Always follow the recommended grade (e.g., 5W-30) in your manual.
  • Using the wrong grade can reduce performance and fuel efficiency.


Additives for Special Needs

  • High-mileage oils can improve the performance of older engines.
  • Specialized formulas cater to unique driving demands.


DIY: How to Change Your Oil


Gather Your Tools

  • Items you’ll need: new oil, filter, wrench, drain pan, gloves, funnel.

Drain the Old Oil

  • Locate the drain plug under the car, remove it, and let the oil fully drain.

Replace the Oil Filter

  • Remove the old filter with a wrench, lubricate the gasket on the new one, and hand-tighten it into place.

Add Fresh Oil

  • Secure the drain plug, pour in the recommended amount of oil, and check the level with a dipstick.

Dispose of Used Oil Responsibly

  • Collect used oil in a sealed container.
  • Drop it off at a recycling facility or participating auto parts store.


Extra Tips to Keep Your Engine Happy


Consistency is Key: Regular oil changes boost fuel efficiency, engine life, and prevent costly repairs.


DIY or Professional: DIY saves money but takes effort. Professionals can spot additional issues during an oil change.


Avoid Mistakes: Overfilling or under-tightening can cause leaks or pressure build-up.


Seasonal Adjustments: Use lighter oil in winter and thicker oil in summer if recommended.


Oil changes are the foundation of a reliable, long-lasting engine. Stay on top of it to keep your vehicle running like a dream!
