Fuel Management and Efficiency

Fuel is typically the largest operating expense in trucking, accounting for 25-30% of total costs. Even small improvements in fuel efficiency translate to significant savings. This comprehensive guide covers fuel management strategies, efficiency optimization, and cost-reduction techniques for fleet operations.

Fuel Cost Reality

The Numbers:

Typical Truck:

Fuel economy: 6.0-7.5 MPG (loaded average)
Annual miles: 100,000-120,000
Fuel consumed: 13,000-20,000 gallons/year
Fuel cost (at $4.00/gal): $52,000-$80,000/truck/year

Fleet Impact:

10 trucks × $65,000 avg = $650,000/year fuel expense
1 MPG improvement = $65,000-$100,000 annual savings

Fuel as % of Operating Costs:

Cost Breakdown:

Fuel: 25-30%
Driver pay: 25-30%
Truck payment/depreciation: 15-20%
Insurance: 5-8%
Maintenance: 10-15%
Other: 10-15%

Why Fuel Matters:

Largest controllable expense
Small % improvement = Big dollar savings
Daily management opportunity

Factors Affecting Fuel Economy

Driver Behavior (40% of fuel economy):

Biggest Impact Factor:

Speed:

55 MPH: 8.0 MPG
65 MPH: 7.0 MPG (12.5% worse)
75 MPH: 6.0 MPG (25% worse than 55)
Every 1 MPH over 65 = 0.1 MPG loss

Idle Time:

1 hour idle = ~1 gallon wasted
Excessive idle (overnight for heat/AC) = 500-1,000 gallons/year wasted
Cost: $2,000-$4,000/year per truck

Acceleration/Braking:

Aggressive driving (rapid acceleration, hard braking) = 5-10% MPG loss
Smooth driving = Better fuel economy

Gear Selection:

Lugging engine (too high gear, low RPM) = Poor efficiency
Over-revving = Wasted fuel
Optimal: 1,200-1,400 RPM cruise

Vehicle Factors (30% of fuel economy):

Aerodynamics:

Roof fairings: 5-10% improvement
Side skirts: 3-5% improvement
Boat tail/trailer tails: 3-5% improvement
Combined: 10-20% total improvement possible

Rolling Resistance:

Low rolling resistance tires: 3-5% improvement
Proper tire inflation: 2-3% improvement
Wheel alignment: 2-3% improvement

Engine Maintenance:

Clean air filter: 2-3% improvement
Proper oil weight: 1-2% improvement
Engine tune: 3-5% improvement

Weight:

Every 1,000 lbs = 0.1 MPG reduction
Lighter truck = Better MPG
Avoid unnecessary equipment weight

Route Factors (20% of fuel economy):

Terrain:

Mountains: 4.5-5.5 MPG (steep grades)
Plains: 7.0-8.0 MPG (flat)
Route selection: Avoid mountains when possible

Traffic:

Highway steady: 7.0 MPG
Stop-and-go: 3.0-4.0 MPG
Avoid congestion when feasible

Weather:

Headwind: -0.5 to -1.0 MPG
Cold weather: -0.3 to -0.5 MPG (engine less efficient)
AC use (summer): -0.2 to -0.4 MPG

Load Factors (10% of fuel economy):

Weight:

Empty: 8.5-9.5 MPG
Half load (25,000 lbs): 7.5-8.5 MPG
Full load (45,000 lbs): 6.5-7.5 MPG

Aerodynamics:

Empty van: Better than loaded (less weight)
Flatbed with tall load: Terrible (wind resistance)
Properly loaded: Weight low and forward

Fuel Efficiency Programs

1. Driver Training:

Fuel Efficiency Techniques:

Speed Management:

Cruise at 62-65 MPH (optimal efficiency)
Use cruise control on highway (consistent speed)
Slow down gradually (avoid hard braking)

Anticipation:

Look ahead for traffic, lights, stops
Coast to stops (don't brake hard)
Maintain momentum

Idle Reduction:

Shut down if stopped over 5 minutes
Use APU for climate control (not main engine)
Limit warm-up time (3-5 minutes sufficient)

Progressive Shifting:

Skip gears when possible (automated transmissions do this)
Don't over-rev engine
Let torque do the work

2. Incentive Programs:

Fuel Bonus Structure:

Example:

Fleet average MPG: 6.8
Bonus threshold: 7.0+ MPG
Bonus: $500-$1,000/year per driver

Calculation:

Monthly MPG tracking
Drivers above threshold earn bonus
Quarterly or annual payout

ROI:

Driver improving from 6.5 to 7.2 MPG = $3,000-$5,000 savings/year
Pay driver $750 bonus = Company nets $2,250-$4,250
Everyone wins

3. Technology Solutions:

Telematics:

Real-time MPG monitoring
Idle time tracking
Speed alerts (over 70 MPH)
Driver scorecards

Coaching:

"Your MPG this week was 6.2, fleet average is 6.8. Let's work on reducing idle time."
Data-driven feedback
Track improvement

Strategic Fuel Purchasing

1. Fuel Tax Optimization (IFTA):

State Fuel Tax Rates Vary:

Highest: Pennsylvania ($0.577/gal), California ($0.537/gal)
Lowest: Missouri ($0.17/gal), Mississippi ($0.18/gal)

Strategy:

Fuel in low-tax states when possible
$0.40/gal difference × 150 gallons = $60 savings per fill

Route Planning:

Fill up in Missouri before entering Illinois
Fuel in Arizona before California
Plan fuel stops in low-tax states

2. Fuel Card Programs:

Major Fuel Cards:

EFS (WEX):

Widely accepted
Reporting and controls
Fleet discounts at major chains

Comdata:

Similar to EFS
Good acceptance
Cash advance features

T-Chek:

Trucking-focused
Factoring integration

Fleet Cards (Chain-Specific):

Loves, Pilot/Flying J, TA/Petro
Loyalty programs (cents off per gallon)
Shower credits

3. Fuel Discounts:

Volume Discounts:

Negotiate with fuel providers
3-10 cents/gallon discount at certain chains
10,000 gallons/month × $0.05 = $500/month savings

Loyalty Programs:

Pilot/Flying J MyRewards
Loves Rewards
TA UltraOne
Earn points/credits, redeem for fuel or services

4. Fuel Network Optimization:

Preferred Stops:

Identify cheapest stops on regular routes
Use apps (GasBuddy, Trucker Path) for real-time prices
Plan fuel stops at low-price locations

Avoid:

Fueling at most expensive states
Last-minute fueling (forced to use expensive station)
Small independent stations (often higher prices)

Idle Time Reduction

Idle Costs:

Fuel Waste:

1 hour idle = ~1 gallon diesel
8 hours overnight idle = 8 gallons = $32/night
250 nights/year = 2,000 gallons = $8,000/year wasted

Solutions:

APU (Auxiliary Power Unit):

Small diesel engine for climate control
Uses 0.1-0.2 gal/hour (vs. 1.0 gal/hr main engine)
Savings: 6-7 gallons/night = $24/night = $6,000/year
Payback: APU costs $8,000-$12,000, payback in 12-24 months

Electric APU:

Battery-powered climate control
No fuel consumption
Recharges while driving
Savings: Even better than diesel APU

Idle Shutdown:

Automatic engine shutdown after X minutes idle
Forces drivers to use APU
Policy enforcement

Driver Coaching:

Idle Tracking:

Monitor idle % via telematics
Target: Under 10% of engine hours
Provide feedback to high idlers

Education:

Explain cost: "8 hours idle = $32 wasted"
Show impact on bonus: "Lower idle = Better efficiency = Higher bonus"

Fuel Efficiency Monitoring

MPG Tracking:

By Truck:

Track each vehicle's MPG
Compare to fleet average
Low MPG truck = Maintenance issue? Driver issue? Both?

By Driver:

Same truck, different drivers = Compare
Identifies efficient vs. inefficient drivers
Coaching opportunity

By Route:

Some lanes naturally lower MPG (mountains)
Account for route difficulty in comparisons

Reporting:

Weekly Dashboard:

Fleet MPG average
Fuel cost this week
Idle time %
Top 3 efficient drivers
Bottom 3 (need coaching)

Monthly Analysis:

Trends (improving or declining)
Seasonal factors (winter = lower MPG)
Action items for improvement
