To make sure your car is running properly, you should regularly check the oil level and replace it when necessary. You should also have regular tune-ups to keep the engine functioning at its peak performance levels. Additionally, ensure that all of your lights, signals, and brakes are working correctly before driving. Finally, inspect the tires for signs of wear or damage and have them checked by a professional if needed.
