Fuel Efficiency Tips
Improve MPG
- Maintain steady speeds and avoid hard acceleration.
- Keep tires inflated to recommended PSI.
- Remove roof racks and excess cargo weight.
Save on Trip Costs
- Plot fuel stops with lower prices before hitting high-cost areas.
- Use gas reward programs or credit card cash-back offers.
- Drive during off-peak hours to avoid traffic and idling.
Track Progress
- Log mileage and fill-ups monthly to catch drops in efficiency.
- Schedule tune-ups—old spark plugs and filters can reduce MPG by 10-20%.
- Compare actual MPG vs. EPA estimates to find inefficiencies.
Electric Vehicle Conversion
Driving electric? Divide kWh used by 33.7 to convert to gallon equivalents and use the MPG mode. Compare electricity rate per kWh versus gas to see savings.
