What is the BTU per gallon for #4 Fuel Oil?

• A. 140,000 BTU/gal
• B. 145,000 BTU/gal
• C. 150,000 BTU/gal
• D. 155,000 BTU/gal

Answer: (B)

BTU per gallon is the energy content of fuel oil per unit volume, used to estimate how much heat a boiler can produce and how many gallons you’ll need. For #4 fuel oil, the energy content is typically about 145,000 BTU per gallon. That makes 145,000 BTU/gal the best standard figure to use in fuel calculations for this fuel type. Exact numbers can vary with batch composition, sulfur content, and temperature, but 145,000 BTU/gal is the commonly used reference value. The other options fall outside the usual range for #4 fuel oil.
