How to Change Engine Oil in an Automobile Engine

Changing the engine oil is a process of great significance for it extends the operational life of a car’s engine. Regardless of the time of year and the driving experience and conditions, a change of oil is required for the engine just as a person needs water (Fracchia, 2019). Otherwise, further problems with a car cannot be avoided because engine oil becomes worse in the course of time and harms automobiles. It thickens clogging the filters or liquefies which leads to the premature wear of engine elements during friction (Fracchia, 2019). Each type of propulsion system requires a specific brand of oil. Its regular renewal contributes to the prolongation of the operational life of a car. The purpose of this paper is to describe the process of changing the oil in an automobile engine.

Laymen can easily cope with an oil renewal as it is a simple issue. Before the beginning of the process, a driver should check the kind and amount of oil required as well as prepare all the necessary supplies (wrenches, a filter, and others). Even though every car might have its peculiarities, the following standard procedure is suitable for the majority of car models. First of all, one needs to warm up the engine system; then, it is important to wait until it cools (Fracchia, 2019). It is possible to incorporate the waiting time for choosing a container where the used grease will be drained. After that, comes the unscrewing of the cap on the crankcase located at the bottom of the pan (Fracchia, 2019). Begin the process with a wrench and then, use your hands. It is important to act carefully for engine grease will immediately pour with a strong stream. Draining usually does not take much time and finishes within 5 minutes (Fracchia, 2019). The next step is pouring new oil into the engine.

It should be mentioned that a complete replacement of grease is impossible. There always remain about 3-4% of the old material in the engine (Fracchia, 2019). However, it is not a matter of concern because the used oil does not influence the performance of an automobile. When changing the engine grease, the condition of the drained engine fluid is assessed for contaminants and unwanted impurities (Fracchia, 2019). Furthermore, an oil measurement with the use of a deep stick is mandatory for it is necessary to set the correct oil level in the engine. Pour 80% of oil at first and then, gradually add more grease to reach the amount desired (Fracchia, 2019). This is the correct method of replacing the used material in the engine with new oil.

A renewal of grease also involves a change of the filter. It is a significant part of the process described because after 8,000 km, filters inevitably clog (Fracchia, 2019). Motor lubricant is filtered to remove unwanted impurities and small debris. If you do not change the filter together with oil, the bypass valve will open and the raw material will go to the engine (Fracchia, 2019). This might lead to the premature wear of the system although no signals will be seen by a driver. In conclusion, changing oil is a procedure that plays an important role in the performance and operational life of an automobile. The above order of actions can help one to do an oil renewal easily without professional help.
