Comprehensive Tables of Common Fuel Cost Variables

The following tables provide typical values utilized in fuel cost calculations, including fuel prices, consumption rates, and distance metrics to suit diverse geographic and transport contexts.

Fuel Type	Price per Liter (USD)	Price per Gallon (USD)	Average Consumption (L/100 km)	Average Consumption (MPG)
Gasoline (Regular)	1.15 – 1.30	4.35 – 4.90	7.0 – 10.0	24 – 34
Diesel	1.05 – 1.20	3.97 – 4.55	6.0 – 9.0	26 – 39
Ethanol (E85)	0.85 – 1.10	3.20 – 4.17	9.0 – 13.0	18 – 26
Propane	0.65 – 0.95	2.46 – 3.59	7.5 – 11.0	21 – 31
Electric (Equivalent kWh consumption)	$0.12 – $0.20 per kWh	N/A	15 – 22 kWh/100 km	N/A

Distances are commonly measured in kilometers (km) or miles (mi). Fuel consumption can be referenced in liters per 100 kilometers (L/100 km) or miles per gallon (MPG), with conversion factors facilitating interchangeability.

Mathematical Formulas for Fuel Cost Estimation

Understanding the fundamental formulas is key to producing accurate fuel cost estimates. Below, all necessary equations are presented with detailed descriptions of each variable.

1. Basic Fuel Consumption Calculation

Fuel Consumption (L) = (Distance (km) × Consumption Rate (L/100 km)) ÷ 100

Distance (km): Total trip distance expressed in kilometers.
Consumption Rate (L/100 km): Amount of fuel consumed per 100 kilometers. Typical values vary by vehicle and load.

2. Fuel Cost Calculation

Fuel Cost (USD) = Fuel Consumption (L) × Fuel Price (USD/L)

Fuel Price (USD/L): Cost of one liter of the chosen fuel type, which fluctuates by region and market conditions.

3. Combined Formula for Trip Fuel Cost

Fuel Cost (USD) = (Distance (km) × Consumption Rate (L/100 km) × Fuel Price (USD/L)) ÷ 100

4. Conversion of Fuel Consumption from MPG to L/100 km

Consumption (L/100 km) = 235.215 ÷ MPG

MPG: Miles per gallon, common in the US and UK fuel metrics.
235.215: Conversion constant derived from 100 km and 1 US gallon equivalent.

5. Fuel Consumption from Fuel Efficiency (%) and Energy Content (Advanced)

For specialist contexts such as fleet or electric vehicle energy modeling, fuel consumption can be related to engine efficiency and fuel energy density.

Fuel Consumption (L) = (Energy Required (MJ)) ÷ (Engine Efficiency × Fuel Energy Density (MJ/L))

Energy Required (MJ): Mechanical energy needed for the trip, calculated via powertrain modeling.
Engine Efficiency: Fraction (0-1) representing how well engine converts fuel energy to mechanical work.
Fuel Energy Density (MJ/L): Energy content per liter of fuel type, e.g., gasoline ≈ 34.2 MJ/L.

Detailed Explanation of Each Variable and Common Ranges

The accuracy of fuel cost estimates rests heavily on understanding each variable’s behavior and expected range.

Distance: Should be verified using precise mapping or GPS data. Typical trip distances can range from short urban trips (~5 km) to extensive cross-country journeys (>1000 km).
Consumption Rate: Varies by vehicle type, driving conditions, and maintenance. For example, compact cars consume 5-8 L/100 km, SUVs and trucks may consume 10-15 L/100 km.
Fuel Price: Subject to market fluctuations, taxation, and fuel type. Prices are often updated daily by agencies like the U.S. Energy Information Administration (EIA) (https://www.eia.gov/petroleum/gasdiesel/).
Unit Conversions: Key for international use or comparison between regions. Remember that 1 gallon (US) = 3.78541 liters, and 1 mile = 1.60934 kilometers.

Real-World Application Cases

Case 1: Fuel Cost Estimation for Regional Delivery Truck

A logistics company operates a diesel truck for regional deliveries. The truck travels 350 km per day. The vehicle’s consumption is 12 L/100 km. Diesel price is $1.10 per liter. Calculate the daily fuel cost.

Step 1: Calculate total fuel consumption.

Fuel Consumption = (350 km × 12 L/100 km) ÷ 100 = (4200) ÷ 100 = 42 L

Step 2: Calculate fuel cost.

Fuel Cost = 42 L × $1.10/L = $46.20

Answer: The truck’s daily fuel expense is $46.20.

Case 2: Passenger Car Fuel Budget for a Cross-Country Trip

A sedan with fuel economy of 30 MPG plans a road trip covering 1200 miles. Gasoline price at the route average is $3.40 per gallon. Calculate the estimated fuel cost.

Step 1: Convert MPG to liters per 100 kilometers.

Consumption in L/100 km = 235.215 ÷ 30 = 7.84 L/100 km

Step 2: Calculate total fuel consumption in gallons.

Fuel Consumption (gal) = Total Distance / MPG = 1200 miles ÷ 30 mpg = 40 gallons

Step 3: Calculate fuel cost.

Fuel Cost = 40 gallons × $3.40/gallon = $136.00

Answer: Estimated fuel cost for the trip is $136.00.

Advanced Considerations In Fuel Cost Computations

Fuel cost estimation models can be extended by incorporating several dynamic parameters to increase precision.

Regenerative Braking and Hybrid Systems: Adjust consumption rates to reflect energy recovered during driving cycles.
Traffic and Load Effects: Heavier payloads and congestion drastically increase consumption; models can incorporate load multipliers.
Weather and Terrain Factors: Elevation changes and temperature affect engine efficiency and fuel usage.
Currency and Taxation Variation: For international operations, conversion and taxation policies must be integrated to yield real cost.
