To ensure that your car is running smoothly and efficiently, you should regularly check the oil levels and replace it when necessary. You should also keep up with regular maintenance such as checking brakes and tires, changing air filters, and getting an oil change every 3,000 to 5,000 miles. Additionally, you may want to consider installing a diagnostic scanner or engine analyzer to help monitor the performance of various components in your car.
