Here’s How You Can Bring Your Auto Back to Its Glory Days
Cars made today are built to last much longer than older models. The Bureau of Transportation Statistics says cars now stay on the road much longer than in the past. With proper care, your car can easily go 200,000 to 300,000 miles without major issues.
If your car has high mileage, it’ll need more upkeep to stay on the road. Staying on top of maintenance and regular checkups is the key to keeping it running smoothly. Over time, you’ll likely notice small changes in how it drives and feels.
Fortunately, there’s still hope for your aging car. Try these five simple tips from Breast Cancer Car Donations to help it run like new again:
- Replace your wheels. If your car still has its original wheels, they probably need replacing. For a budget-friendly fix, look for a service that can weld and straighten them.
- Clean out your AC. Deep clean your car’s AC system. Change the air filters, clear out any dust and grime and deodorize to kill mold, bacteria, and that old-car smell.
- Replace your shocks and ball joints. If your car has hit 100,000 miles, chances are parts like shock absorbers and ball joints need replacing. Don’t wait for them to break – swap them out now to boost performance.
- Flush all your vehicle’s fluids. Flush and replace all your car’s fluids, including antifreeze and power-steering fluid. If you’ve already changed one recently, feel free to skip that one.
- Have your engine thoroughly checked. Bring your car to a shop for a full inspection. Even if nothing’s broken, have them replace any parts that are worn or affecting engine performance.
Taking these steps can help your high-mileage car feel almost new again. Still have questions about keeping your vehicle in top shape or wondering how long it can last? Here are some helpful answers to common concerns:
Can updating my car’s software help it run better?
Many modern cars rely on software to optimize driving and engine behavior, so software updates or engine tunes can improve performance, fuel economy and fix general bugs.
Do carbon deposits hurt my engine, and how do I clean them?
Carbon buildup reduces engine power and fuel efficiency. Use fuel system cleaners regularly or get a professional intake cleaning to restore performance and prevent long-term damage.
Should I use high-mileage or synthetic oil?
Yes! High-mileage and synthetic oils handle heat more effectively than conventional oil, especially in older vehicles. They offer better protection for aging engines by reducing wear and preventing leaks.
Why should I replace old rubber parts like belts and hoses?
Old rubber belts and hoses dry out, crack and fail over time. Having a mechanic replace them prevents breakdowns and overheating as well as engine damage caused by coolant or timing failures.
Can a bad catalytic converter or oxygen sensor hurt my car’s performance?
Yes. A failing catalytic converter or oxygen sensor disrupts fuel mixture and emissions, causing poor mileage, rough idling and potentially damaging your engine or exhaust system.
Will new spark plugs and ignition parts help?
Fresh spark plugs and ignition component repairs can certainly help. They improve combustion, which leads to smoother engine operation, quicker starts, better fuel efficiency and reduced emissions.
Should I clean under the car to stop rust?
Yes! Washing the undercarriage removes salt, dirt and moisture that cause rust, which is especially important in snowy or coastal areas. It helps extend your vehicle’s lifespan and structural integrity.
