How many BTUs does one gallon of oil produce?

1. 100,000 BTUs

2. 140,000 BTUs

3. 250,000 BTUs

4. 300,000 BTUs

The correct answer is: 140,000 BTUs

One gallon of oil produces approximately 140,000 BTUs (British Thermal Units) of energy. This value is important because it helps determine the heating potential of oil as a fuel source. The 140,000 BTUs per gallon metric is widely recognized in the energy sector, making it a standard reference for heating calculations. Understanding the energy output from a given volume of fuel is crucial for those involved in heating systems, as it assists in evaluating energy needs, fuel efficiency, and cost-effectiveness when comparing oil to other energy sources. In contrast, the other values listed are inaccurate representations of the energy produced per gallon of oil. While the actual number can vary slightly based on the specific type of oil, the widely accepted figure is indeed around 140,000 BTUs.
