Red Seal Oil Heat System Technician Practice Exam

What unit is commonly used to measure heating oil consumption?

1. Gallons

2. Cubic feet

3. Liters

4. Barrels

The correct answer is: Gallons

Gallons is the unit commonly used to measure heating oil consumption primarily in North America. This measurement is widely recognized in the oil heating industry because heating oil is typically stored and sold in this volume. The use of gallons aligns with how tank capacities are usually labeled and how fuel delivery is scheduled and invoiced. While other units like liters and barrels are used in different contexts—liters being more prevalent in countries that use the metric system and barrels often used for larger quantities, such as in crude oil—gallons remains the standard measurement for domestic heating oil consumption. Therefore, it is essential for technicians and professionals in the field to be familiar with this unit for accurate assessment and communication regarding fuel usage.
