What is the BTU per gallon for #6 Fuel Oil?

• A. 160,000 BTU/gal
• B. 140,000 BTU/gal
• C. 145,000 BTU/gal
• D. 150,000 BTU/gal

Answer: (D)

BTU per gallon measures how much energy is released when a gallon of fuel is burned, which is essential for estimating fuel needs and boiler fuel consumption. For No. 6 fuel oil, the standard value used in MFBO practice is about 150,000 BTU per gallon. This rounded figure is widely used for budgeting, sizing, and calculations because it reflects typical energy content for this heavy fuel under common conditions. In reality, the exact BTU per gallon can vary with fuel composition, temperature, and batch, but 150,000 BTU/gal remains the conventional reference. For example, to estimate gallons needed for a heating requirement, you’d divide the total BTU by 150,000 and adjust for boiler efficiency.
