Regular maintenance for a car includes checking and changing the oil and oil filter, checking and replacing the air filter, checking and replacing the spark plugs, rotating and balancing the tires, checking and replacing the brake pads and rotor, checking the coolant and transmission fluid levels, and checking the battery and charging system. It's also important to have regular inspections and tune-ups performed by a qualified mechanic. Following these steps can help ensure your car runs smoothly and can prevent costly repairs in the future.

It is recommended to have your car's oil changed every 3,000 miles or 3 months, whichever comes first. However, it's also a good idea to check your car's owner manual for the manufacturer's recommended intervals. Some newer cars can go longer between oil changes, such as 7,500 or even 10,000 miles and 6 or 12 months for time. It's also important to note that if you drive frequently in stop-and-go traffic, tow a trailer, or make frequent short trips, you may need to change your oil more frequently.

To prevent costly repairs, it is important to regularly check and maintain various systems and components of the car, including the oil and filter, tires, brakes, battery, and coolant level. Additionally, keeping up with recommended service schedules, such as regular tune-ups and tire rotations, can help maintain the car's overall health and prolong its lifespan. It is also important to address any warning lights or strange noises as soon as they occur, rather than waiting for them to become bigger problems.
