1. Neglecting Regular Oil Changes
Regular oil changes are key for your car’s engine. They keep it running smoothly and prevent damage. Skipping oil changes can cause engine problems and expensive fixes.
Not changing oil when needed can lead to engine sludge. This can cut engine efficiency by 40%. It’s important to follow the oil change schedule your car’s maker suggests.
Driving habits affect how often you need to change oil. Frequent stops and starts mean oil changes every 3,000 to 5,000 miles. Newer cars might need oil changes every 8,000-10,000 miles. Sticking to these schedules helps keep your engine in good shape.
- About 50% of car owners rarely or never change oil on time. This raises the risk of engine failure.
- Cars with regular oil changes last about 200,000 miles longer than those without.
Make regular oil changes a priority. It helps your car last longer and avoids common mistakes in car care.
2. Ignoring Tire Maintenance
Keeping your tires in good shape is key for your car’s safety and how well it runs. We often forget about tire care, which can cause big problems. Not taking care of your tires can lead to blowouts and accidents, making it a major mistake.
Checking your tires regularly is important to avoid these issues. Tire pressure is a big part of keeping tires healthy. Tires lose air when it gets colder, which can make your car use more gas and wear unevenly. Most car makers say to check and rotate tires every 5,000 miles to keep them lasting longer.
Importance of Tire Pressure
Checking tire pressure, including the spare, helps your car use less gas and wear tires evenly. If tires are not the right pressure, your car might use 3% more gas for every 1 PSI drop. Keeping the right pressure helps your car run better and stay safe.
The Role of Tire Rotation
Rotating tires regularly can make them last 25% to 50% longer by wearing them evenly. This simple step helps prevent uneven wear and blowouts. It’s a key way to keep your car safe and running well.
3. Skipping Brake Inspections
Regular brake inspections are key for your car’s safety. They help spot worn brake pads and rotors. Skipping these checks can cause brake failure and accidents, making it a big car maintenance pitfall to avoid. The National Highway Traffic Safety Administration (NHTSA) says about 25% of cars have brake problems that can be dangerous.
Some common car upkeep blunders include not checking brakes regularly. Ignoring signs like squeaking or grinding noises is also a mistake. Not replacing brake pads and rotors on time can lead to expensive repairs and accidents. For reliable car maintenance tips, check out this car maintenance guide.
