If your car suddenly has a bad odour or starts making noises while you are driving it, you may have some car trouble. You should also check that the car is running properly and that all its lights are operating correctly. You might be able to tell if your car needs an oil change if it is making noises while you are driving, or if you have any trouble starting it, but usually this is not the problem.
Other signs you may have trouble with your car are oil pressure and engine performance. If your oil is low, you need to make sure you check it regularly, especially if you drive a lot. You can do this by opening up your oil dipstick, turning the engine over, and checking the oil level. If the oil is too low, you should replace it. If you notice that your engine is making unusual noises while you are driving, and the car does not respond when you start it, then you should have your engine checked by an auto mechanic.

If you notice any symptoms that your engine is not running correctly, such as the vehicle becoming difficult to start, or the engine losing power on its own, then you need to have your engine checked. Your oil level will usually be lower than normal, so your engine is probably not starting at full power, or it is not responding as well as normal. If you do not feel comfortable getting in your car to check your engine, you should call a mechanic who can take a look.
