For many years, experts have recommended changing the oil in a car every 3,000 miles. While you may not need to change the oil in your car that often, changing it regularly is important. If you fail to ever change the oil, problems in your engine are highly likely to occur. Here are several things that can happen if you never change the oil in your car:

The Oil Will Thicken

While your car may never burn oil, which means that it may always have a sufficient amount in it, the oil will thicken over time. The oil in your car is there for several key purposes, and one of the main things it does is lubricate the parts within the engine. As oil gets old, it tends to become thicker and unable to lubricate the parts as it should. This can result in worn-out engine parts.

The Engine Will Get Dirty

One of the reasons oil thickens over time is due to the way it cleans an engine. The oil runs throughout the engine cleaning the parts it lubricates. As it cleans them, it picks up debris from the engine. The purpose of this is to keep the engine cleaner. If the oil is old and thick, it will also be very dirty and will no longer be able to clean the engine. The result of this is that the engine will become dirty. When this occurs, the engine will have to work harder to perform. This will often cause you to lose efficiency in your gas mileage, and it may cause parts of the engine to stop working altogether.

It Will Not Cool the Engine

The other key purpose and duty of engine oil is to cool an engine. An engine gets very hot as it runs. To cool it, the oil in the car spreads throughout the parts of the engine and provides enough cooling for it. Old, used engine oil is not capable of doing this. If you fail to change the oil in your car, it will eventually no longer cool the engine at all. If this happens, the engine will overheat and shut down.

If you want your car to run well and last for a very long time, it is important to change the oil. You can do this by scheduling a visit with an auto repair center in your city for an oil change service.
