How can I tell if my car needs a tune up?

To determine if your car needs a tune-up, you should check the oil and coolant levels. You may also want to listen for any strange noises or vibrations coming from the engine. If these are all within normal range, then it is likely that your car does not need a tune-up. However, if there are any issues with performance or power, then you should consult a professional mechanic to have the tune-up done.
