Auto maintenance advice is everywhere—friends, online forums, quick-lube stickers, and even well-meaning recommendations that aren’t always accurate for your vehicle.

The problem is that bad advice often leads to one of two outcomes:

• People overspend on services they don’t need, or
• People skip maintenance that actually prevents expensive breakdowns

Here are common maintenance myths—and how to make smart decisions with confidence.

Myth #1: “If the car is running fine, I don’t need maintenance.”

Many issues don’t show symptoms until they’re expensive:

• Worn fluids
• Weak batteries
• Cooling system issues
• Small leaks

Maintenance isn’t about today—it’s about avoiding surprises later.

Myth #2: “Every car needs an oil change every 3,000 miles.”

Modern engines and oils vary widely. Your correct interval depends on:

• Oil type
• Driving habits (short trips, idle time, towing)

The best approach: follow the right interval for your vehicle and usage, not a one-size-fits-all sticker.

Myth #3: “Flushes are always a scam.”

Some flushes are unnecessary. Some are absolutely valuable.
What matters is:

• Condition of the fluid
• Vehicle mileage and history
• Manufacturer service intervals
• Symptoms (overheating, shifting issues)

A trustworthy shop explains why a service is recommended and whether there are alternatives.

Myth #4: “If it’s not leaking, my fluids are fine.”

Fluids can break down long before a leak appears.
Old fluid can lose protective properties and increase wear.

A proper inspection looks at:

• Color and condition
• Odor (burnt fluid)
• Contamination
• Age and mileage

Myth #5: “The cheapest service is the best deal.”

Low prices sometimes mean:

• Lower quality parts or fluids
• Shortcuts on procedures
• Limited warranty support
• Missed inspections that catch bigger issues

The right question isn’t “What’s the cheapest?”
It’s “What’s the best value with clarity and integrity?”
