Gas Mileage Calculator
An easy way to calculate gas mileage is to remember the odometer reading or to reset the mileage counter when filling up a gas tank. When doing so next time, obtain the mileage accrued between the two gas fill-ups. Then divide the mileage figure by the amount of gas filled the second time to obtain the gas mileage.

đ How to Improve Gas Mileage?
Carpooling, public transport, or walking/bicycling are the best options for someone looking for the best possible gas mileage, or fuel efficiency. If not viable, here are some pointers to getting the most fuel efficiency:
Drive a fuel-efficient vehicle
Overall, 4-wheel drive vehicles tend to be less fuel efficient than FWD or RWD. By powering all four wheels, the engine works harder to move a car the same speed at higher speeds.
Maintain proper tire pressure
Under-inflated tires can lower gas mileage by 0.3% per PSI drop. Rigidity in tires allows for greater frictional interaction between rubber and the road. Ensure wheels are properly aligned.
Optimal speed: 55 MPH (90 km/h)
According to studies by the U.S. Department of Energy, 55 MPH is optimal for fuel efficiency. Use cruise control when possible. Relative to 55 MPH, a vehicle is:
- âĸ 3% less efficient at 60 MPH
- âĸ 8% less efficient at 65 MPH
- âĸ 17% less efficient at 70 MPH
- âĸ 23% less efficient at 75 MPH
- âĸ 28% less efficient at 80 MPH
Avoid aggressive driving
Aggressive acceleration and braking can improve gas mileage by 15-30% at highway speeds and 10-40% in stop-and-go traffic. Steady acceleration is safer and more efficient.
Keep vehicles in good shape
Use recommended motor oil, keep the engine properly tuned, ensure the oxygen sensor works, and check air filters regularly. This can improve gas mileage by 1-2%.
Remove unnecessary weight
The heavier the object, the more fuel required to move it. Remove heavy items not being used and avoid unnecessary roof racks or trailers.
