Vehicle Fuel Management Flashcards

Which metric best measures the cost-effectiveness of a fleet's fuel consumption across mixed vehicle types?

Answer: Cost per mile

Cost per mile normalizes fuel costs across vehicles with different fuel types, tank sizes, and MPG ratings, enabling fair comparison.

A fleet manager notices fuel purchases significantly exceed mileage records. What is the most likely cause?

Answer: Fuel card misuse or theft

When fuel purchases consistently outpace recorded mileage, fuel card fraud or theft is the primary suspect and should trigger an audit.

What is the purpose of establishing fuel spend benchmarks by vehicle class in a fleet?

Answer: To identify outliers and investigate anomalies

Class-level benchmarks allow fleet managers to flag vehicles or drivers whose fuel spend deviates significantly from the norm for investigation.

Which fueling method provides the greatest control over fuel quality and prevents unauthorized purchases?

Answer: On-site bulk fuel storage

On-site bulk fuel storage lets fleet managers control fuel quality through testing, restrict access, and eliminate off-site unauthorized purchases.

Under EPA regulations, which of the following is required when an underground fuel storage tank (UST) is taken out of service temporarily?

Answer: The tank must be properly closed with empty and cap procedures

EPA UST regulations require temporary closure procedures including emptying the tank and capping all lines to prevent contamination.

What does a fuel hedge strategy protect a fleet against?

Answer: Fuel price volatility

Fuel hedging uses financial instruments to lock in fuel prices, protecting the fleet budget from unexpected price spikes.

A fleet using E85 ethanol blend should be aware that vehicles consume approximately how much more E85 than gasoline to travel the same distance?

Answer: 15–27% more

E85 contains less energy per gallon than gasoline, so flex-fuel vehicles typically consume 15–27% more E85 to achieve equivalent range.

Which technology automatically records fuel dispensed, vehicle ID, and timestamp at a fleet fueling site?

Answer: Automated fuel management systems (AFMS)

Automated fuel management systems use card readers or RFID to capture fueling data in real time, linking each transaction to a specific vehicle.

What is the primary reason fleet managers monitor idle time in relation to fuel management?

Answer: Idling burns fuel without producing useful mileage

A vehicle idling burns fuel at roughly 0.5–1 gallon per hour while generating zero miles, directly inflating fuel cost per mile.

When evaluating telematics data for fuel management, which driver behavior has the single largest impact on fuel consumption?

Answer: Speeding above posted limits

Sustained high-speed driving significantly increases aerodynamic drag and fuel consumption, making speed the dominant fuel-consumption behavior factor.

A fleet manager wants to reduce fuel theft at off-site retail locations. Which fuel card control is most effective?

Answer: Limiting cards to specific geographic areas

Geographic restrictions prevent cards from being used outside the fleet's operating territory, directly limiting unauthorized use far from work routes.

What is 'fuel shrinkage' in the context of bulk fuel storage management?

Answer: The difference between fuel delivered and fuel dispensed

Fuel shrinkage is the unaccounted variance between volume received from the supplier and volume dispensed, indicating evaporation, leaks, or theft.

Which CAFM best practice helps ensure compressed natural gas (CNG) vehicles are fueled safely and efficiently?

Answer: Training drivers on CNG fueling procedures and leak detection

CNG is stored at high pressure and requires specific fueling procedures; driver training on safe handling and leak detection is essential.

A fleet manager calculates a fuel variance of +8% (more fuel purchased than consumed). What is the recommended first action?

Answer: Audit fuel card transactions against vehicle odometer records

Cross-referencing fuel card transactions with odometer data identifies specific vehicles or drivers where the discrepancy originates before taking corrective action.

Which alternative fuel is most compatible with existing diesel infrastructure and requires the fewest engine modifications for fleet use?

Answer: Biodiesel (B20)

B20 biodiesel can be used in most diesel engines without modification and is dispensed through existing diesel infrastructure with minimal transition costs.

What does 'fuel economy standard' refer to in the context of US federal fleet regulations?

Answer: Corporate Average Fuel Economy (CAFE) standards

CAFE standards set by NHTSA require automakers to meet average fuel economy targets across their vehicle fleets, influencing which vehicles fleet managers can procure.

A fleet manager is implementing a fuel management dashboard. Which KPI combination provides the most comprehensive fuel program overview?

Answer: Cost per mile, MPG by vehicle class, and fuel variance percentage

Combining cost per mile, class MPG, and variance percentage captures efficiency, cost, and loss-control dimensions of fuel management in a single dashboard view.

What is the primary advantage of using a centralized fuel management vendor (fuel card network) over multiple local accounts?

Answer: Consolidated reporting and single-point controls

A centralized network provides unified transaction data, consistent controls, and a single reporting interface that simplifies auditing across a dispersed fleet.

When a fleet operates vehicles in multiple US states, which fuel tax compliance program simplifies reporting?

Answer: IFTA (International Fuel Tax Agreement)

IFTA allows multi-state motor carriers to file a single quarterly fuel tax return covering all member jurisdictions instead of filing separately with each state.

Which factor most significantly affects the accuracy of bulk fuel inventory reconciliation?

Answer: Temperature compensation of fuel volume measurements

Fuel volume changes with temperature; without temperature compensation (converting to 60°F standard), inventory records will show false variances across seasons.
