One of the most important functions of a petroleum manager is the adequate forecasting of petroleum
requirements. Without an accurate forecast of requirements, the orderly flow of petroleum products is
threatened. There are five methods for computing petroleum requirements. They are listed in order from
best to worst: historical data method, combat profile, fuel consumption unit (STANAG 2115), equipment
consumption, and gallons per person per day.
PART A - HISTORICAL DATA METHOD
The historical data method is the best method and considers the following factors: same vehicles, same
distances, and similar resupply source, weather, and terrain. Record keeping for actual consumption during
major training exercises and tactical marches is essential for correct calculations using this method.
PART B - COMBAT PROFILE
The combat profile method tracks combat vehicles only. You must use FM 101-10-1/2, Table 2-12, Combat
Consumption Rates for Bulk Fuels (Figure 3-1) to obtain consumption rates (factors) and Table 2-14, Daily
Equipment Usage Rates for Tracked Combat Vehicles (Figure 3-2). Add together subtotals (shown below)
and multiply by number of vehicles to get the total fuel requirement.
PART C - FUEL CONSUMPTION OF UNIT
The NATO STANAG 2115 method is a standard used by NATO in determining fuel consumption. The fuel
consumption unit (FCU) considers combat, terrain, and climate. You must use tables found in FM 101-10-
1/2, Table 2-12, Combat Consumption Rates for Bulk Fuels (Figure 3-1) (excerpt provided) to obtain
consumption rates (factors), Table 2-13, Daily Equipment Usage Rates for Other than Tracked Combat
Vehicles (Figure 3-3), and FM 10-13, Table 3-1, Additional Situations (Figure 3-4), (excerpt provided)..
= TOTAL GALLONS
PART D - EQUIPMENT CONSUMPTION
When using the equipment consumption method, you must know what equipment is to be used (TOE, TDA,
or equipment listing) and must use FM 101-10-1/2, Tables 2-12, Combat Consumption Rates for Bulk Fuels
(Figure 3-1, excerpt provided) to obtain consumption rates (factors), Table 2-13, Daily Equipment Usage
Rates for Other than Tracked Combat Vehicles (Figure 3-3, excerpt provided), and Table 2-14, Daily
Equipment Usage Rates for Tracked Combat Vehicles (Figure 3-2, excerpt provided). This method may be
used at all levels. Here is an example:
= Fuel Rate
PART E - GALLONS PER PERSON PER DAY
