How can I tell if my car needs a tune up?
Check your engine oil level. If it is low, you may need to have the oil changed or check for any other issues with your engine that could require a tune-up. 2 Check your vehicle’s performance. Does the engine seem sluggish or hard to start? This could be an indication of a tune-up being needed. 3 Listen for strange noises coming from the engine. A tune-up can help reduce these noises and improve overall engine performance. 4 Look at your vehicle's dashboard lights. These lights are designed to alert you when certain components in the engine need servicing. 5 Take your vehicle to a mechanic to get it checked out. They will be able to diagnose any problems and recommend what needs to be done.
