Your vehicle is a significant investment, and proper maintenance can extend its life by tens of thousands of miles while preventing costly repairs. At Poynor Auto, we've seen countless vehicles suffer premature wear because of neglected maintenance. Here's what every car owner should know.

1. Oil Changes: More Important Than You Think

Motor oil lubricates engine components, reduces friction, and carries away heat and contaminants. Over time, oil breaks down and collects debris, losing its effectiveness.

Our recommendation: Follow your manufacturer's interval, but consider shortening it if you frequently drive in dusty conditions, tow trailers, or make short trips that don't allow the engine to fully warm up. Synthetic oil typically lasts longer but costs more upfront.

2. Tire Pressure Affects Everything

Underinflated tires wear out faster, reduce fuel economy, and can affect handling. Overinflated tires make the ride harsher and wear the center of the tread faster.

• Check tire pressure monthly when tires are cold
• Look for the recommended psi on the door jamb sticker, not the tire sidewall
• Don't forget the spare tire

3. Replace Air Filters Regularly

A dirty air filter restricts airflow to the engine, reducing performance and fuel economy. In dusty Mississippi conditions, we recommend checking filters every 6 months or 12,000 miles.

4. Watch Your Fluid Levels

Beyond engine oil, your vehicle relies on several fluids:

• Coolant: Prevents overheating and protects against corrosion
• Brake fluid: Essential for safe stopping; absorbs moisture over time
• Power steering fluid: Keeps steering smooth and responsive
• Transmission fluid: Lubricates gears and keeps shifting smooth

5. Pay Attention to Warning Lights

That check engine light isn't just an annoyance—it's your vehicle's way of telling you something needs attention. While it could be something minor like a loose gas cap, it could also indicate serious issues like catalytic converter problems or engine misfires.

Our advice: Don't ignore warning lights. A small problem caught early typically costs a fraction of what it would after ignoring the warning.

6. Brakes Are Not Something to Skimp On

We understand budget constraints, but brake work is not an area to cut corners. Squeaking brakes are your pads' way of saying they need attention. Grinding means metal is contacting metal—potentially damaging rotors and compromising safety.

7. Keep It Clean

Regular washing does more than maintain appearances. Road salt and grime can accelerate rust, particularly in wheel wells and undercarriage. A clean engine bay makes leaks easier to spot and can prevent fires from accumulated grease and debris.

8. Don't Ignore Unusual Sounds or Vibrations

Your vehicle communicates through sounds and sensations. A small rattle today could be a major failure tomorrow. The earlier we can diagnose an issue, the less expensive the repair typically is.

When to Call a Professional

While many maintenance tasks are DIY-friendly, some require professional attention:

• Any work requiring specialized tools or equipment
• Electrical system diagnostics
• Suspension component replacement
• Transmission service
• Complex engine diagnostics
