Probably the most common maintenance stop for any vehicle is an oil change. Depending on the make, model, and age of your vehicle, oil changes may be required fairly frequently in order to keep your vehicle in good working condition. Though, with our busy schedules, it can be hard to make time for an oil change. So what really happens to your car if you do not regularly change the oil?

What Does Oil Do?

The oil in your vehicle has one main purpose and that is to keep all the components in the engine running smoothly. There are many moving pieces within your car's engine that move, turn, and slide to propel your car. As these various components move, friction forms as the parts rub and move against one another. Friction can create a great amount of heat within the engine, which can eventually cause damage. By keeping the oil in your vehicle fresh and clean, parts are able to move freely between one another. With parts moving easily, less friction, and thus less heat, forms under the hood of your car.

So My Car Has Oil Already?

Yes, while your car does have oil already, it is necessary to regularly change the oil. As all the mechanical parts move through the engine, tiny bits of debris can collect. This debris floats around in the oil, making it thick and less viscous. If the oil is thick and dirty, friction can build up more quickly than it does in clear oil.

What Happens to My Car Without an Oil Change?

Without regular oil changes, your engine can start to experience several problems. The engine will run too hot, causing damage to the internal pieces. The mechanical parts within an overheated engine can become worn out before they are due, or can become misshapen and distorted. If an engine part is slightly warped or out of shape, it will not work as intended. This can cause undue stress on other parts of the engine and create a cascade of engine trouble.
