Changing the oil in a car is a necessary component of proper automotive maintenance; it is the intent of this article to going into the specifics of why this is so. This article intends to explain the importance of this procedure by citing all of the things that can go wrong when the same oil is left within the vehicle beyond the recommended period of time.
Before this article goes into the reasons why an oil change is necessary, it is important to define what an oil change is. In brief, an oil change is a process of draining a vehicle of all its oil and replacing it with a fresh supply. The primary purpose of motor oil is to serve as a lubricant and to mitigate the development of sludge and other impurities within the vehicle. While the frequency by which a car owner should have an oil change varies with the entity asked and the distances regularly traveled by the car, a good rule of thumb is to change out the oil every 7,500 to 10,000 miles.
With all of the reasons and explanations out of the way, let us assess the drawbacks to not changing out the oil in a car when the odometer has gone well past the recommended mileage.
- You lose out on fuel efficiency. As motor oil does its work of minimizing the friction between the engine’s moving parts, it degrades in quality. This degradation means that the vehicle has to expend more energy just to keep up with the performance of a properly oiled version of itself. This increased energy consumption also means that the vehicle’s power output will diminish in tandem with its fuel efficiency.
- You increase the chances of damaging your car. If the old, fatigued oil is left within the engine for a considerable amount of time, the progressive buildup of impurities can lead engine damage. As motor oil ages, its ability to lubricate moving parts diminishes; diminished lubrication leads to increased buildup of heat. Excess levels of heat can literally erode engine parts, with an engine-killing explosion being the worst possible outcome. The presence of metal shavings in the removed oil is a surefire sign of the sort of damage that results from excess heat.
- Increasing maintenance costs. After accounting for the previous two points about not changing oil, it should become obvious that the cost to maintain an operational vehicle will only increase with time.
After reading over the points raised in this article, we hope you see why an oil change is a vital component of any proper maintenance job. Care for your car by maintaining its oil.
