Not changing your oil can result in a plethora of problems that center around costly repairs that could have been avoid with a basic oil change. Oil changes are relatively inexpensive and are a car maintenance necessity. The oil inside your engine acts as a vital lubricant allowing the metal parts to move smoothly. If your oil is not changed in a timely manner it can result in engine sludge. This sludge inside of your engine will cut down its performance dramatically. When this occurs your gas mileage will suffer greatly and overheating on hot summer days is more likely to happen.
When a car is running the movement of the engine creates particles of debris which will find their way into the oil of the engine. When changing the oil it clears out all of these harmful pieces of debris which are causing damage to the internal components of the engine. Frequent oil changes will most defiantly contribute to a cleaner and better working engine. It has also been proven that the most common causes of engine wear are caused by friction. Therefore by completing these oil changes you dramatically decrease your chance of engine failure in your vehicle.
A common misunderstanding is that people think dark oil means dirty oil. In reality dark oil signifies that the oil is doing its job. In time motor oil will break down, this is why it needs to be replaced. Today oil has become an advanced science that involves additives that slow the degradation process down. But as with all oil it will eventually break down over time as the vehicle is used. As we take a look back on what we have discussed about engine oil, here are some important reasons why one should change their oil on a consistent basis, reduced friction, stable temperature, cleaner engine, better mileage and lower emissions.
