Keeping your car in tip-top shape can help prevent unnecessary repair bills and unexpected trips to the mechanic. One essential car maintenance task is a routine oil change. Oil changes are a must for proper vehicle care, but they can be easy and relatively inexpensive.
Oops. Something went wrong with the CTA block.
Your car’s engine is complex and contains numerous moving parts. Oil lubricates these moving parts and keeps everything running smoothly, says Angie’s List. Over time some of the motor oil burns off — leaving a thick sludge behind. This sludge reduces the oil’s ability to lubricate the parts properly, which can lead to engine wear. Checking your oil can help determine if the oil needs to be changed and if there is enough in the car.
According to Cars.com, here are some of the reasons why you should change your car’s oil:
Consumer Reports suggests that drivers check their oil at every other gas fill-up. Start by consulting your owner’s manual. It should contain information on how to check the oil in your vehicle. Once your car is parked on level ground and the engine is off, Consumer Reports recommends these steps for checking your oil:
Which kind of oil you use in your vehicle depends on your engine’s needs and the manufacturer’s recommendations in the owner’s manual. You can choose synthetic oil, conventional oil or high-mileage oil, depending on your engine’s needs and the expected oil life. Also, you’ll need to choose the right viscosity for your engine — that information is typically found on your engine’s oil cap or in the vehicle’s owner’s manual.

Every car manufacturer has a slightly different recommended oil change schedule. Consult your owner’s manual to find your car manufacturer’s suggested oil change interval. When a dealership or service center changes your vehicle’s oil, they will typically put a sticker on your window to tell you when your car is due for another oil change.
When you have the oil changed, it’s a good idea to check the oil filter, as well. You may also want to perform other routine maintenance, such as checking the brakes, rotating the tires and topping off fluids, says Angie’s List. Be sure to ask your mechanic what inspections they perform during an oil change. Routine oil changes are a key part of car maintenance to help keep your vehicle running smoothly. If you need help checking or changing your oil, consult a car care professional.

Proper brake pad maintenance is not only critical for helping your car last, but also for your safety as a driver or passenger. Simply put, your vehicle’s brakes are what enable you to slow down and stop. To help ensure your vehicle can stop safely, consider these tips on when and how to check your car’s brake pads.
Oops. Something went wrong with the CTA block.
There’s no specific schedule for when it’s time to replace your brake pads, according to Cars.com. That means it’s a good idea to check your brake pads regularly to help determine the amount of wear and tear. Typical brake pad wear depends on how and where you drive, says Cars.com. For example, if you drive in urban areas, your brake pads may wear out faster than they would if you drove on rural roads due to the stopping and starting of city traffic.
Whether you go to a professional mechanic or handle maintenance yourself, it’s a good idea to check the brake pads each time your tires are rotated — about every six months, says Cars.com. It’s also a good idea to check your car owner’s manual or talk to a professional technician so you understand what service schedule and parts may be right for your particular vehicle.
Fortunately, brake pads are designed to provide clear signals that they need to be checked and possibly replaced. Here are some ways to check your brakes:
Here are a few ways you can be in-tune with your brakes and whether it’s time to have them checked.
If you have concerns about whether or not your brake system is functioning properly, you should have it inspected by a professionally immediately.
It can also be helpful to take a look at your brakes to see if there are any obvious signs of wear and tear. When the car is parked safely and the ignition is off, follow these tips for visually inspecting your brake pads:
Cars.com says some common signs that may indicate it’s time to replace your brake pads include:
If you do not feel comfortable checking your brake pads, take your vehicle to a local dealership or repair shop where a professional can do it for you. Not only will replacing worn brake pads help make your car safer, it may help save money in the long run by helping prevent avoidable accidents.

Have you ever pulled your car into your garage, opened the car door and accidentally hit the wall? Just like that, the side of your car door has a ding. We’ve all been there, but there’s an inexpensive way to help avoid dents and dings. A pool noodle may be the key to helping protect your car doors, according to Precision Garage Door of Salt Lake.
Watch this video to see how a pool noodle can become a bumper for your car door.
Oops. Something went wrong with the CTA block.
First, gather these materials:
Use a utility knife or box cutter to cut the pool noodle in half lengthwise. Take care when cutting — do this step on a flat surface such as a workbench or the garage floor. You may also want to consider wearing work gloves while cutting.
Carefully open your car door to determine where it makes contact with the garage wall. Using a pencil, lightly mark the point of contact on the wall. Using that mark as your guide, draw a longer line horizontally across the wall. If desired, you can use a measuring tape to make sure you are extending your line at the correct height or for the length of the pool noodle.
Sign up for our email newsletter.
Cut two strips of mounting tape the length of the pool noodle. Apply these strips of tape to the edges of the noodle. Then, attach the noodle to the wall, horizontally along the line you marked earlier.
Alternatively, The Family Handyman says you could use nails to attach the pool noodle to the wall to really help it stay in place. However, be sure to use the appropriate tools and nails for your garage wall.
Again, carefully open the car door. It should now touch the soft pool noodle instead of the wall. If it doesn’t, remount the noodle at the appropriate height.
No one likes dents in their car, especially when it is from something as simple as opening the door. Use this quick fix to help avoid door dings by mounting a simple pool noodle to your garage wall.

Do your car windows need a good cleaning? There may be a simple solution in your cabinets. According to Reader’s Digest, a mixture of vinegar, ammonia and cornstarch can help you get sparkling car windows without leaving streaks.
Oops. Something went wrong with the CTA block.
Start by gathering the ingredients you need to make the glass cleaning solution:
You’ll also need a clean bucket to use while you’re mixing the solution. When the cleaner is ready, you’ll need a spray bottle and clean cloth, such as a microfiber towel, to use while cleaning.
Follow these steps to get clean windows without pesky streaks.
In a bucket, combine 2 tablespoons of cornstarch with ½ cup ammonia, ½ cup white vinegar and 3 to 4 quarts of warm water. Mix the ingredients together — Reader’s Digest says it’s normal for it to look milky.
Pour the finished mixture into an empty spray bottle. Then, spray the solution onto your car window.
Wipe the window with warm water to rinse off the solution and loosened dirt. Then, use a lint-free cloth or paper towel to dry the window.
Repeat this process for each window on your vehicle.
For best results, consider these window-cleaning tips from Angie’s List:
Making sure your car windows are clean not only helps your car to look it’s best, but can also help improve visibility while you’re driving. With this homemade glass cleaner and a little effort, you’ll have a clearer view of the road ahead.

Seeing children grow and reach developmental milestones can be a rewarding experience for parents. But, some of those milestones, like helping your teen get a driver’s license or buying a car for your young driver, may come with some concerns and uncertainty. It helps to do some research to find the right car for your teen’s situation. These tips can help you get started with buying a car for your teen driver.
When choosing a car for your teen, vehicle size matters for a few reasons. For example, large, heavier cars may seem more difficult for a new driver to handle at first. But, bigger vehicles typically perform better in crash tests than their smaller counterparts, according to Consumer Reports. On the flip side, it’s important to consider that a larger vehicle usually allows for more passengers (which can be a potential driving distraction). While doing your research, it may be a good idea to check your state’s graduated driver licensing laws to understand how many passengers your teen may be allowed to have in their vehicle.
Oops. Something went wrong with the CTA block.
Sports cars are one type of car that should be avoided for teens, says Consumer Reports, because they have a higher rate of accidents when compared to other types of vehicles. These types of vehicles can also have high horsepower, which may tempt your teen to test its limits, says the Insurance Institute for Highway Safety. Consider your teen’s abilities and maturity level, and your budget, when choosing which size vehicle may be right for them.
Safety is likely a top priority when it comes to a car for your teen. Newer cars generally offer more safety features and have better crash protection, says Consumer Reports, so you may want to take the age of a car into consideration when choosing a vehicle.
It’s also a good idea to check a vehicle’s safety ratings. In addition to the ratings supplied by car manufacturers, consider looking at results from a safety-research group. One example is the 5-star rating program that the National Highway Traffic Safety Administration (NHTSA) administers each year to determine how new vehicles perform in front, side and rollover crash testing. A 5-star rating indicates the safest cars. In 2010, NHTSA also began assigning an overall vehicle score to tested cars along with a list of their included safety technologies, which may be helpful when comparing newer vehicles.
Some newer cars also include advanced safety features. Forward-collision warning, for example, provides drivers with visual or audio warnings when another car or object is in its path, says Consumer Reports. New vehicles may also include automatic emergency braking or a blind spot warning system, which can help drivers avoid an accident by alerting them of vehicles in their blind spot.

Costs related to routine maintenance can vary from vehicle to vehicle. Consider expenses such as the price of oil changes, parts and tires. If you buy a luxury car for your teen, for example, it may cost more to fix when something goes wrong, says AutoTrader. This is because many luxury cars have higher-end gadgets and use specialized parts, making maintenance more expensive than an average car. Or, you may want to consider that larger cars can cost more to fuel up since they typically have a lower fuel economy when compared to smaller cars, says Consumer Reports.
After finding a potential car for your teen, you may also want to speak with an insurance agent to estimate the insurance costs so you know what to expect.
No matter which vehicle you choose for your teen, combining a reliable car with a responsible driver can help maximize the safety of your teen and their passengers. Remember these tips when researching vehicles so you can choose a car that meets your priorities and is appropriate for your teen.

Planning on driving to Mexico? The following guidelines can help you plan for your drive in Mexico. Keep reading to learn about some laws and unspoken customs before your trip.
Here are seven tips to keep in mind for your drive:
As a U.S. driver, you’re likely accustomed to road signs, strict right-of-way laws and traffic signals. Make sure you know the speed limits and understand the rules of the road in Mexico before you travel.
Oops. Something went wrong with the CTA block.
The Department of State advises driving on toll roads for increased safety and better road conditions. This is also recommended because outside of major cities in Mexico, emergency or police services may be limited.
Here are some common road conditions to look out for, according to USA today:
Driving in the daylight may be easier and safer in Mexico, says the Department of State. Remember, police or emergency services may be limited in some areas of Mexico (especially at night). The Department of State also advises visitors to avoid driving alone, if possible.
Turn signals in Mexico can be used to mean more than one thing, according to USA Today. For example, if you’re on the highway and the driver in front of you uses his left turn signal, this could indicate that it’s safe for you to pass him.
Oncoming drivers in Mexico will often enter your lane of the road to pass other vehicles, says Trip Savvy – and it’s typically expected that other vehicles will move over to accommodate them. If a vehicle is approaching in your lane from the opposite direction, you should move over and drive on the shoulder to allow them to pass.
You will cross a customs checkpoint when re-entering the United States. You’ll be asked to declare anything you purchase while in Mexico, says the Department of Homeland Security. You can find a complete list of items you can’t carry across the border on the U.S. Customs and Border Protection website here.
Your U.S. auto insurance won’t cover you after crossing the border of Mexico. You’ll need a special Mexican auto insurance policy to legally drive in Mexico, which can be acquired through an insurance agent. If you’re planning to drive a rental car in Mexico, you may be able to purchase the insurance coverage directly through the rental agency, according to the Department of State.
Preparing for your drive ahead of time can help ensure you have a thorough understanding of what to expect while driving in Mexico. An agent can also help you find long-term or short-term insurance coverage options that are a good fit for your trip and needs.

If you live in an area where winter means driving on icy, snow-covered roads, you likely understand how challenging those road conditions can be on your car — not to mention how stressful it can be for the driver. There are a few things you can do, though, to help ensure your tires have as much traction as possible. Consider these tips to help prepare your tires for winter weather:
Your tires’ tread is what gives them their ability to grip the road. So, one of the first ways to tell if your tires are ready for winter roads is to examine the tread on each tire, including the spare. The National Highway Traffic Safety Administration (NHTSA) recommends checking your tires at least once a month. If a tire has uneven or excessive wear, it should be replaced.
NHTSA says tire tread depth should be a minimum of 2/32 of an inch. To check this, hold a penny between your thumb and forefinger so that Lincoln’s head is showing. Place the top of Lincoln’s head into one of the grooves of the tire’s tread. If any part of Lincoln’s head is obscured by the tread, you have a safe amount of tread, according to NHTSA. If you can see above Lincoln’s head, then you need a new tire.
Tires that are not inflated to the correct pressure may negatively affect your car’s handling, according to Cars.com. And, as the temperatures outside drop, the NHTSA says your tires will lose pressure. This is why it’s important to check your tire pressure throughout the winter.
The recommended tire pressure for a vehicle is typically listed on a sticker inside the driver’s door, or it can be found in the owner’s manual, says Cars.com. Use a tire pressure gauge, which you can get at most gas stations or auto parts stores, to check that each tire is at the correct pressure. (Edmunds recommends checking the tires before driving, as the friction created when driving affects the pressure.) If necessary, use an air compressor to inflate the tires. If any of the tires are overinflated, use the small bead on the back of the tire pressure gauge to release some air.

You might think winter tires are only for areas where the winter weather conditions are very harsh, with lots of ice and snow. But, winter tires, which used to be called snow tires, are designed to work in lower temperatures regardless of road conditions, according to Road and Track Magazine. In fact, colder temperatures may cause standard tires to become too hard and lose their normal traction, even when the roads are dry.
There are several types of tires you may want to consider for winter driving:
Your local mechanic or car dealership can help you decide which tires make sense for your area’s weather, and they can also recommend appropriate tires for your vehicle.
While preparing your car for the winter takes a little extra work, it can be worth it in the long run. Your car’s tires can help keep you safe on the road during winter, so remember these tips when preparing for the new season.

During those cold winter months, you may often find your windshield covered in frost. Maybe you let the car run with the defrost on, or you get out an ice scraper to clear your windshield. But, Meteorologist Ken Weathers has a tip that may help you clear up the frost quickly and with less effort.
Oops. Something went wrong with the CTA block.
Put on rubber gloves, then mix two parts rubbing alcohol with one part water. (Do not use hot water, Weathers says, because it may crack your windshield. Room temperature or cold water is fine. Isopropyl alcohol can be used instead of rubbing alcohol, too.)
Pour the mixture into an empty spray bottle.
Spray the mixture onto your windshield, and watch the frost clear up.
You can even leave the spray bottle with the mixture in your car, because rubbing alcohol has a freezing point of 128 degrees below zero (in Fahrenheit), says Weathers.
As the temperatures drop, be ready for frosty days by having this simple defrosting spray at hand. By spending a few minutes to make this mixture, this quick fix can help you get on the road a little quicker.

When dealing with the frigid temperatures of winter, there’s not much worse than coming out to your car to find the doors frozen shut. According to Lifehacker, car doors can freeze because water from rain or snow gets into the rubber seal, or gasket, around the door and then freezes when the temperatures drop. Fortunately, there is a simple trick that may help prevent this from happening, using nothing but ordinary household cooking spray.
Apply the spray to the door’s rubber seal weekly during the coldest winter months, or as needed before expected icy, frigid storms, says Brian L. Gochenour, laser operations manager and sales engineer at Broadway Metal Works.
Oops. Something went wrong with the CTA block.
Any ordinary cooking spray should work.
Open your car door, and look for the rubber gasket all around its edge. Spray the rubber on the top, side and bottom of the door with the cooking spray.
Take a dry paper towel and gently rub the rubber seal to get rid of drips and excess spray.
Apply the cooking spray to each door on your car. This should help prevent the doors from freezing shut, and you’ll be able to get into your vehicle with ease in the cold weather.

While Black Friday shopping may bring exciting deals and the fun of finding a bargain, the traffic and parking can be a challenge. Parking spaces are limited, people always seem to be in a rush to get to the next stop and the roads are congested. But with a little planning, you may be able to avoid the added stress driving and parking can create. As you head out to tackle your holiday shopping this year, remember these Black Friday traffic and parking tips.
Checking out the sales ads and figuring out where you need to go before leaving your house can help keep your day moving smoothly. Popular Science suggests creating a driving route based on what stores you plan to visit. Prioritize your route by the items you want the most, which stores have great deals or which retailer opens the earliest, says The Balance. By not bouncing from one side of town to the other all day, you may be able to maximize your shopping time and get done earlier so you only have to deal with a few hours of traffic on Black Friday.
Oops. Something went wrong with the CTA block.
With so many bargain hunters looking to get to their next stop, you may want to consider downloading a traffic app before the big day. Techlicious notes that there are a number of navigation apps available that can help you plan the quickest route, avoid traffic jams and provide turn-by-turn directions.
It can be helpful to enter your route into your GPS device or cellphone ahead of time, so you’re ready to navigate the busy roads. And, if your app provides traffic information, it may help you find a better route if the crowds are backing up traffic.
According to the National Safety Council (NSC), both drivers and pedestrians are likely to be distracted and rushed during the holiday season — stating that the number of accidents spikes each year on Black Friday. On a day when traffic is heavy and you may feel rushed and flustered, the last thing you need is an accident. To limit distractions, put cellphones away and leave the music off.
The NSC recommends that drivers avoid cutting across lanes on roads and in parking lots. Use extra caution when backing out of parking spots, and watch for pedestrians, especially children and parents pushing strollers. Remember to keep a safe distance from the car in front of you and use extra caution throughout the day.
Between drivers looking for open spots, jam-packed lots and narrow aisles, Black Friday parking can be an accident waiting to happen. But by remembering these simple tips from International Parking and Mobility Institute, you can take some extra precautions that may help prevent major problems:
With so many people out on the road the day after Thanksgiving, you may run into some unexpected hassles — no matter how well you plan. While you can’t predict what Black Friday traffic will be like, if you remember these tips and take the necessary precautions, things may go a little more smoothly.
