Frequently Asked Questions
How do you calculate fuel cost for a trip?
Divide distance by MPG, then multiply by gas price. 500 mi ÷ 30 MPG × $3.50 = $58.33.
What is good gas mileage?
30+ MPG is good for gas cars, 40+ MPG is excellent. Hybrids get 45-60 MPG.
How do I convert MPG to L/100km?
L/100km = 235.215 ÷ MPG. So 30 MPG = 7.84 L/100km.
Does driving faster use more gas?
