How do I know if my car is running properly?

Check your engine oil level. Make sure it's at the proper level and that there are no visible signs of oil leakage or smoke coming from the engine. 2 Listen for any unusual noises coming from the engine. If you hear strange sounds, such as a clunking noise or grinding, then your car may be in need of repair. 3 Test drive your car to make sure all systems work properly. Pay attention to how quickly the car accelerates, brakes, turns, and stops. 4 Take your car to a mechanic for an inspection. A professional will be able to identify any problems with your car's performance and suggest repairs.
