What is the specified engine oil type for the fire pumps?

The correct engine oil type for fire pumps is SAE 15W-40. This grade of oil is highly regarded for its ability to perform well in a range of temperatures and operating conditions, making it particularly suitable for fire pump engines that may be used in various environmental conditions. SAE 15W-40 oil provides effective lubrication at both lower and higher temperatures, ensuring that the engine components are protected regardless of the operational demands placed on the fire pump.

In addition to temperature performance, SAE 15W-40 oil typically has enhanced properties that help reduce engine wear, improve fuel efficiency, and control deposits that can accumulate over time. These characteristics are critical for fire pumps that must operate reliably under stress and demand efficient performance during emergency situations.

While other oil types may be suitable for different engines or applications, they do not offer the same balance of cold start performance and high-temperature stability as SAE 15W-40, which is why this particular oil specification is preferred for fire pump operations.
