10 of the most frequently asked questions about vehicle maintenance.
Based on a Gemini AI inquiry, we take a look at the 10 most frequently asked questions online around maintaining your vehicle. Here are our responses along with some of our experts weighing in.
1. How often should I change my oil?
This is often the most common question. The answer varies depending on your vehicle's make, model, and the type of oil it uses (conventional vs. synthetic).While the old rule was every 3,000 miles, many modern cars can go 5,000 to 10,000 miles or more between changes. Your vehicle's owner's manual is the most accurate source for this information as well as a check-in with your service technician.
2. When should I replace my tires and how do I check the pressure?
Tires are a critical safety component. You should replace them when the tread wears down to a certain point (you can check this with the "penny test").Tire pressure should be checked monthly and before long trips, and the correct pressure can be found on a sticker inside the driver's side door jamb, not on the tire's sidewall.
3. Why is my "Check Engine" light on?
This light can indicate a wide range of issues, from something as simple as a loose gas cap to a more serious engine problem. It's best to have the issue diagnosed by a professional as soon as possible to prevent a minor issue from becoming a major repair.
4. How often should I get my brakes checked?
Brake pads typically last between 25,000 and 70,000 miles, but this can vary greatly based on driving habits. You should have your brakes inspected regularly and pay attention to warning signs like squealing or grinding noises, a "spongy" feeling when you press the pedal, or vibrations.
5. What are the most important fluids to check?
Engine oil is the most well-known, but there are several other vital fluids.8 These include brake fluid, coolant (antifreeze), transmission fluid, power steering fluid, and windshield washer fluid.9 Keeping these at the proper levels is crucial for your vehicle's performance and longevity.10
6. How long do car batteries last?
Most car batteries last between 3 to 5 years. Signs of a dying battery include slow engine cranking, dim headlights, or the battery warning light coming on. Extreme temperatures can shorten a battery's lifespan.
7. Do I need to rotate my tires?
Yes. Regularly rotating your tires (typically every 5,000 to 7,500 miles) helps them wear more evenly, which extends their lifespan and improves your vehicle's handling and fuel efficiency.
8. What does it mean if my car is making a strange noise?
Unusual sounds like squealing, grinding, or knocking can be a sign of an underlying mechanical issue. It's important to pay attention to these noises and have a professional inspect the car to prevent further damage.
9. What are the most important maintenance tasks for different seasons?
Maintenance needs can change with the weather. For winter, it's important to check your battery, tire tread, and antifreeze levels. For summer, you should check your air conditioning system and make sure your coolant is at the correct level to prevent overheating.
10. Can I perform basic maintenance myself?
Many people can handle simple tasks like checking tire pressure, topping off windshield washer fluid, and even replacing an air filter. However, for more complex tasks or anything related to safety systems like brakes, it's always best to consult a professional mechanic.
