Question 1

How do I calculate fuel cost for a road trip?

Accepted Answer

Divide the total distance by your vehicle's fuel economy (MPG) to get gallons needed, then multiply by the current gas price. For example, a 300-mile trip in a 30 MPG car at $3.50/gallon costs (300/30) x $3.50 = $35.

Question 2

What is the average MPG for a car?

Accepted Answer

The average new car in the US gets about 28-30 MPG combined. Compact cars average 32-38 MPG, SUVs average 22-28 MPG, trucks average 18-24 MPG, and hybrid vehicles average 40-55 MPG. Electric vehicles are measured in MPGe (miles per gallon equivalent).

Question 3

How can I improve my fuel economy?

Accepted Answer

Maintain steady speeds and avoid rapid acceleration, keep tires properly inflated (can improve MPG by up to 3%), remove excess weight from the vehicle, use cruise control on highways, and keep up with regular maintenance like air filter and spark plug replacements.

Question 4

How do I convert MPG to L/100km?

Accepted Answer

To convert MPG to L/100km, divide 235.21 by the MPG value. For example, 30 MPG = 235.21/30 = 7.84 L/100km. To convert L/100km to MPG, divide 235.21 by the L/100km value.
