Frequently Asked Questions
How do I calculate fuel cost for a trip?
To calculate fuel cost, you need to know your vehicle's fuel efficiency (MPG or L/100km), the distance of your trip, and the current fuel price. Divide the total distance by your vehicle's MPG to get gallons needed, then multiply by fuel price per gallon. Our calculator does this automatically and also handles metric conversions.
How can I save on fuel costs during a road trip?
To save on fuel costs: maintain proper tire pressure, remove excess weight from your vehicle, use cruise control on highways, avoid excessive idling, plan efficient routes, drive at moderate speeds (55-65 mph is typically most efficient), and use apps to find the lowest fuel prices along your route.
What's the difference between MPG and L/100km?
MPG (miles per gallon) and L/100km (liters per 100 kilometers) are different ways to measure fuel efficiency. MPG is common in the US and tells you how many miles you can drive on one gallon of fuel—higher is better. L/100km is used in most other countries and tells you how many liters of fuel are needed to travel 100 kilometers—lower is better. Our calculator supports both systems.
