In the firefighting world, the terms “engine truck” and “squad” refer to two different types of apparatus, each serving unique roles. An engine truck, often simply called an “engine,” is primarily equipped for fire suppression. It carries water, hoses, and pumps, designed to extinguish fires by delivering water to the fire scene. In addition to firefighting equipment, engines often carry basic tools for forcible entry, ventilation, and sometimes basic life support equipment.

Engine oil, crucial for lubricating and cooling engine components, typically appears as a light brown to amber liquid when new, thanks to its refined petroleum or synthetic base and various additives for performance enhancement. However, with use, it darkens to a black or dark brown hue due to the accumulation of byproducts from engine operation, such as microscopic wear metals and soot. The alteration not only changes its color but signifies the oil’s deterioration and the need for replacement to prevent engine damage. Its viscosity, ranging from thin and fluid to thick, depends on its grade and environmental temperature, affecting its appearance and flow characteristics. Observing the color and consistency of engine oil can be an indicator of engine health and maintenance needs. Regular checking and timely replacement, as per the manufacturer’s recommendations, ensures the longevity and efficiency of the engine.
