Planning Your Fuel Budget
Fuel is often the single largest variable cost of a road trip. Knowing your vehicle's real-world efficiency and the current price at the pump lets you budget accurately before you leave — and compare the true cost of different routes or vehicles.
Real-World vs. EPA Ratings
Official mpg or L/100km ratings assume ideal conditions. Highway speed, cargo weight, tire pressure, and climate control can shift your actual efficiency by 10-20%.
Comparing Routes
A slightly longer route with fewer stops and steady highway speeds can sometimes cost less in fuel than a shorter route through heavy stop-and-go traffic.
Tips to Reduce Fuel Costs
Maintaining steady speeds, keeping tires properly inflated, removing excess cargo weight, and using cruise control on the highway are among the most effective ways to improve real-world fuel economy without changing vehicles.
Shop Around
Fuel prices can vary 10% or more between nearby stations — checking a price-comparison app before a long trip can add up to real savings.
Key Takeaways
- Use Your Own Data: For the most accurate estimate, use your vehicle's actual observed mpg or L/100km rather than the factory rating.
- Cost per Mile: This figure is useful for comparing the true cost of driving versus flying or renting a more efficient vehicle.
- Round-Trip Reminder: Don't forget to double the distance if you're calculating fuel for a round trip.
