Is engine oil added into the engine?

Engine oil is not added directly into the engine, but rather into the valve cover chamber through a dedicated oil filler tube. Adding oil directly into the engine can be corrosive to the machinery. Engine oil, also known as engine lubricant, serves multiple functions including lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption. It is often referred to as the 'blood' of a car. Engine oil consists of two main components: base oil and additives. The base oil forms the primary constituent of the lubricant, determining its fundamental properties, while additives compensate for and enhance the performance shortcomings of the base oil, providing additional beneficial characteristics. Additives are an essential part of engine lubricants.

Yes, engine oil is primarily added into the engine. I've developed the habit of adding it myself during every maintenance session since I started driving twenty years ago. Usually, you'll find a cap labeled 'oil' under the hood - just open it and pour directly inside. It's not just a simple top-up procedure; the oil plays critical roles like lubricating cylinder pistons to prevent wear, assisting heat dissipation to keep machine temperatures in check, and cleaning out generated debris. If the oil gets too old or insufficient, engine noise increases and fuel consumption rises. I regularly check the fluid level using the dipstick: wipe it clean, reinsert, then check that the reading stays within the optimal middle range. Before long-distance drives, I always pop the hood for a quick visual inspection to confirm I'm using the right type (such as full synthetic oil), which extends engine lifespan and saves maintenance costs.

Absolutely, engine oil is added into that big iron block under the hood. I learned this firsthand when driving my sports car - once forgot to change the oil and the engine started buzzing dangerously. Actually, after locating the oil filler cap, just pour in the recommended oil type from the manual. It not only lubricates but also cools the system to prevent overheating and engine seizure. Modern engines are so tightly packed that running without oil is practically suicidal. My routine is adding some oil first, starting the engine to circulate it, then checking the dipstick level - never fill to the brim, leave some room. Pay attention to change intervals (5,000-10,000 km depending on usage). Beginners often overlook this, but just like blood to a heart, oil is vital for engines. Choosing the right viscosity saves fuel, reduces noise, and significantly improves driving smoothness.

Indeed, engine oil is added inside the engine, and I always keep this in mind when driving my kids to school. As the family driver, maintaining engine lubrication and cleanliness with oil is crucial for ensuring driving safety, especially during rainy days when braking relies on it for cooling. I usually open the oil cap in the engine compartment and carefully pour it into the container to avoid spills, then use the dipstick to ensure the oil level is in the middle. I teach my kids that it's like how people need to drink water timely—don't delay oil changes during the season, and using synthetic oil makes it more wear-resistant. I also clean the air filter to extend the engine's health. With no major repairs needed for ten years, I feel much more at ease.
