What is the oil capacity and type required for the engine?

The oil capacity and type required for the engine of the 45-Foot Response Boat-Medium (RB-M 45) is specifically designed to optimize performance and protect the engine components. The correct answer indicates that the engine requires 43 quarts of 15w40 oil.

This choice is correct because 15w40 oil is a multi-viscosity oil that provides good performance in a wide range of temperatures, making it suitable for marine environments where conditions can vary significantly. The capacity of 43 quarts ensures that the engine has enough oil to operate efficiently without the risk of running low, which is crucial for maintaining lubrication and preventing engine wear.

In summary, using 15w40 oil with the specified 43-quart capacity ensures proper engine function, longevity, and reliability, which are essential for the operational standards of the RB-M 45.
