What is the total oil capacity of the engine?

The total oil capacity of an engine is an important specification that helps ensure proper lubrication and operation. Knowing the oil capacity aids in maintaining the engine, allows for accurate oil level checks, and informs the pilot when it's time for an oil change or refill.

In this case, the correct answer indicates that the engine has a total oil capacity of 6 quarts. This specific value is likely based on the manufacturer's guidelines for that particular engine model, which is essential to follow for optimal performance. An engine that is overfilled or underfilled with oil can lead to serious operational issues, such as poor lubrication, increased wear, or even catastrophic failure.

Other options may represent capacities that could apply to different engines or situations but do not reflect the specified capacity of this particular engine model. Understanding and memorizing specific capacities for your aircraft's engine is crucial for safe operation and maintenance practices.
