How do I calculate fuel cost for a trip?

Divide trip distance by vehicle fuel efficiency (MPG or L/100km) to get gallons/liters needed, then multiply by fuel price per unit.

What is a good fuel efficiency?

Modern cars average 25-35 MPG. Hybrids can achieve 50+ MPG. SUVs and trucks typically get 18-25 MPG. Driving habits significantly impact efficiency.

How can I improve fuel efficiency?

Maintain proper tire pressure, reduce excess weight, avoid aggressive acceleration, use cruise control, keep your vehicle serviced, and drive at moderate speeds.

How to Calculate Fuel Costs

Calculating trip fuel costs is straightforward. Divide your total distance by your vehicle's fuel efficiency to get the gallons or liters needed, then multiply by the current fuel price per unit.

Formula:

Fuel Needed = Distance ÷ Fuel Efficiency
Total Cost = Fuel Needed × Price per Unit
Cost per Mile = Total Cost ÷ Distance

Tips to Save Fuel

Maintain Proper Tire Pressure: Underinflated tires reduce fuel efficiency by up to 3%
Remove Excess Weight: Every 100 lbs of cargo reduces MPG by about 1-2%
Drive Smoothly: Aggressive acceleration and speeding significantly reduce fuel efficiency
Use Cruise Control: Maintaining constant speed on highways improves efficiency
Keep Your Vehicle Serviced: Regular maintenance ensures optimal engine performance
Plan Efficient Routes: Shorter routes with less stop-and-go traffic save fuel
Limit Idling: Disable engine start-stop features off or minimizes unnecessary idling

Fuel Efficiency Comparison

Compact Cars: 25-35 MPG - Good balance of efficiency and affordability

Hybrids: 50+ MPG - Excellent fuel economy, best for high-mileage drivers

SUVs/Crossovers: 18-28 MPG - Lower efficiency but more cargo space

Trucks: 15-25 MPG - Vary widely based on size and engine type

Electric Vehicles: Very low operating costs, no fuel needed
