Disclaimer

Fuel economy calculations are estimates based on your input. Actual fuel efficiency may vary based on driving conditions, vehicle maintenance, and driving habits.

What is a Fuel Economy Calculator?

A fuel economy calculator determines your vehicle's fuel efficiency by calculating miles per gallon (MPG), kilometers per liter (km/L), or liters per 100 kilometers (L/100km) based on distance traveled and fuel consumed.

Essential for tracking fuel costs, comparing vehicle efficiency, planning road trips, and making informed decisions about vehicle purchases or driving habits.

How to Calculate Fuel Economy

1

Fill your gas tank completely and record the odometer reading

2

Drive normally until you need to refuel

3

Fill the tank again and record gallons/liters added and new odometer reading

4

Calculate: Distance traveled ÷ Fuel used = Fuel economy

Fuel Economy Standards & Ratings

Excellent (30+ MPG / 12.8+ km/L)

Hybrid vehicles, small efficient cars, and diesel engines typically achieve this level.

Good (25-30 MPG / 10.6-12.8 km/L)

Compact cars, efficient sedans, and well-maintained vehicles often reach this range.

Average (20-25 MPG / 8.5-10.6 km/L)

Mid-size cars, crossovers, and older vehicles typically fall in this category.

Poor (Below 20 MPG / 8.5 km/L)

Large SUVs, trucks, performance cars, and vehicles needing maintenance.

Frequently Asked Questions

What factors affect fuel economy?

Driving speed, acceleration habits, vehicle maintenance, tire pressure, weather conditions, and cargo weight all impact fuel efficiency.

How can I improve my fuel economy?

Maintain steady speeds, avoid rapid acceleration, keep tires properly inflated, remove excess weight, and perform regular vehicle maintenance.

What's the difference between city and highway MPG?

Highway driving typically yields better fuel economy due to steady speeds, while city driving involves more stops and starts, reducing efficiency.
