The Importance of Oil Changes: Facts & Myths

When it comes to vehicle maintenance, few services are as essential—and as misunderstood—as the oil change. Despite being one of the most basic forms of preventative care, it’s often neglected or surrounded by outdated advice and myths. At Yeargan’s Top Notch Automotive, we’re here to clear things up with the facts, bust the myths, and explain why regular oil changes are crucial for your engine’s health and performance.

Why Oil Changes Matter

Motor oil plays a vital role in your engine. It lubricates moving parts, reduces friction, keeps internal components cool, and helps trap debris and sludge to keep everything running clean. Over time, oil breaks down and loses its effectiveness—especially under high heat or heavy use.

Skipping oil changes can lead to:

• Decreased fuel efficiency

• Sluggish performance

• Engine overheating

• Costly internal damage or failure

Common Myths (And the Truth Behind Them)

🔧 Myth #1: You need an oil change every 3,000 miles

• This used to be true decades ago, but not anymore. Most modern vehicles can safely go 5,000 to 7,500 miles—or even longer—with synthetic oil. Some newer vehicles even require synthetic oil only. Check your owner's manual or ask us for a recommendation based on your driving habits and vehicle type.

🔧 Myth #2: You don’t need an oil change if you don’t drive much

• Even if your vehicle sits most of the time, oil still ages. It can absorb moisture and break down over time, which means time-based intervals (like every 6–12 months) are still important—even for low-mileage vehicles.

🔧 Myth #3: Dark oil always means it’s dirty

• Fresh oil can darken quickly as it does its job, especially in high-mileage engines. What matters more is the oil’s consistency and the presence of metal shavings or sludge—not just the color.

🔧 Myth #4: Synthetic oil causes leaks in older engines

• Quality synthetic oils are actually better at cleaning and protecting engine components. If an oil leak appears after switching to synthetic, it usually reveals an existing issue—not something the oil caused.

How Often Should You Change Your Oil?

There’s no one-size-fits-all answer. Your ideal oil change interval depends on:

• Your driving conditions (city traffic, towing, short trips, etc.).

• The age and type of your vehicle.

• Whether you use conventional, synthetic blend, or full synthetic oil.

At Yeargan’s, we’ll always recommend the right schedule and oil type to keep your engine running smoothly for years to come.

The Bottom Line

Regular oil changes are one of the simplest and most cost-effective ways to extend the life of your engine, improve gas mileage, and avoid expensive repairs. Don’t wait for a warning light—make oil changes part of your regular maintenance routine.
