If your car is shaking, it could be a sign that it's time for an oil change. Over time, oil breaks down and loses its ability to lubricate and protect your engine. This can lead to your engine parts wearing down, which can cause your car to shake.
If you're not sure whether your car needs an oil change, it's always best to consult your owner's manual or ask a professional mechanic. They can help you determine whether your car's shaking is due to a need for an oil change or something else.
