Question 1

How do I calculate fuel cost for a trip?

Accepted Answer

Divide your trip distance by your fuel efficiency (e.g., miles per gallon or km per liter), then multiply by the fuel price per unit. For example: 300 miles / 30 mpg = 10 gallons x $3.50 = $35.00 fuel cost.

Question 2

What is the difference between MPG and L/100km?

Accepted Answer

MPG (miles per gallon) is used in the US and UK. L/100km (liters per 100 kilometers) is the metric standard. Higher MPG means better efficiency, while lower L/100km means better efficiency. To convert: L/100km = 235.21 / MPG.

Question 3

How can I reduce my fuel costs?

Accepted Answer

Maintain steady speed, avoid rapid acceleration, keep tires properly inflated, remove excess weight, use cruise control on highways, and plan efficient routes. Regular maintenance also improves fuel efficiency.

Question 4

Does fuel cost change with driving conditions?

Accepted Answer

Yes. City driving uses 20-30% more fuel than highway driving due to frequent stops and starts. Cold weather, hilly terrain, and heavy loads also increase fuel consumption.
