Why Four Stroke Engine Oil is Necessary?

As a car enthusiast, I have always been fascinated by the workings of engines. And one crucial component that plays a significant role in keeping an engine running smoothly is the engine oil. In this case, specifically, four stroke engine oil. But why is it necessary? Let me share my experience and knowledge on the topic.

First and foremost, four stroke engine oil acts as a lubricant for the various moving parts within the engine. The pistons, crankshaft, and valves all require smooth movements to function properly. Without adequate lubrication, these parts can rub against each other and cause friction, leading to wear and tear. This not only affects the performance of the engine but also reduces its lifespan.

In addition to lubrication, four stroke engine oil also serves as a coolant. As the engine runs, it generates a lot of heat due to combustion. The oil absorbs this heat and disperses it throughout the engine, preventing it from overheating. Without proper cooling, the metal components can expand and warp, causing damage to the engine.

Moreover, four stroke engine oil contains additives that help in cleaning and protecting the internal parts of the engine. Over time, deposits such as dirt, dust particles and even
