How engineering crews adapted from coal to oil

How happy were engineering crews when warships changed from coal to oil?

They generally became happier with oil, but experienced coal-era engineers initially disliked relying on gauges instead of directly inspecting their fuel.

Engineering crews ultimately welcomed the move away from coal, but the transition was not instantly comfortable. Senior engineers accustomed to walking into a bunker and judging the remaining coal by sight, touch, and even smell now had to trust tank-level instruments. Oil simplified many labor-intensive tasks while introducing a different way of monitoring weight and balance. The exchange also distinguishes coke as coal processed to remove impurities and notes that its use depended on the particular ship and auxiliary machinery.
