5–10% fuel savings typical.
Speed Governors
| Setting | Fuel Savings |
|---|---|
| 55 mph max | Major (vs unlimited) |
| 62-65 mph max | Significant |
| 70 mph max | Moderate |
For trucks, 5 mph reduction = 7-10% better fuel economy.
Driver Training
| Training Topic | Fuel Impact |
|---|---|
| Smooth acceleration | -10% improvement |
| Anticipating traffic | -5% improvement |
| Coasting | -5% improvement |
| Cruise control use | -5% improvement |

| Idling awareness | Variable |
Driver training: $200-$500 per driver, savings 10x.
Vehicle Selection for Fuel Efficiency
| Vehicle | MPG Improvement |
|---|---|
| Older sedan | 25 MPG |
| Modern sedan | 35 MPG (-30% fuel) |
| Older pickup | 16 MPG |
| Modern pickup | 22 MPG (-30% fuel) |
| Older van | 14 MPG |
| Modern van | 20 MPG (-30% fuel) |
| Hybrid | -30% to -50% |
| EV | $0.05/mile vs $0.15 gas |
Replacement strategy major fuel impact.
Tire Pressure Monitoring
| Detail | Impact |
|---|---|
| Underinflated | -1% MPG per 1 PSI low |
| TPMS in newer vehicles | Standard |
| Aftermarket TPMS | $50–$200 |
| Weekly checks | Driver responsibility |
| Wireless TPMS | $100–$300 |
Proper inflation: 1-3% better fuel economy.
Maintenance Impact on Fuel
| Item | Fuel Impact |
|---|---|
| Air filter | -10% if clogged |
| Spark plugs | -5% if worn |
| Tire alignment | -10% if off |
| Wheel bearings | -5% if worn |
| Engine condition | Variable |
| Oil quality | -2% if wrong viscosity |
Regular maintenance = fuel savings.
Fuel Hedging (Large Fleets)
| Detail | Note |
|---|---|
| Lock in fuel price | For 6-12 months |
| Hedge against increases | Risk management |
| Requires expertise | Financial knowledge |
| Volume requirement | Million+ gallons typically |
| Costs upfront | Premium for protection |
For fleets with significant fuel exposure.
EV Transition for Fuel Savings
| Comparison | Detail |
|---|---|
| Gas pickup | $0.15/mile fuel |
| EV pickup (Lightning) | $0.04/mile electricity |
| Annual savings (15K mi) | $1,650/vehicle |
| 5-year savings | $8,250/vehicle |
Major fuel cost reduction with EVs.
Fueling Strategy
| Strategy | Detail |
|---|---|
