Calculate fuel consumption, costs, and efficiency. Plan your trips, track your vehicle's efficiency, and estimate fuel expenses easily.
Most vehicles achieve better fuel efficiency on highways than in city driving. Highway driving typically results in 15-30% better fuel economy due to sustained speeds and less stop-and-go traffic.
Cold weather can reduce your fuel efficiency by 10-20%. This happens because your engine takes longer to reach optimal temperature and winter-grade fuel typically has slightly less energy.
Fuel efficiency typically peaks around 50-60 mph for most vehicles. For every 5 mph you drive over 60 mph, you can reduce fuel economy by approximately 7%. Aerodynamic drag increases exponentially with speed.
An extra 100 pounds in your vehicle could reduce your MPG by about 1%. The reduction is based on the percentage of extra weight relative to the vehicle's weight, so smaller vehicles are more affected by extra weight.
