Understanding Your Fuel Costs
Planning a road trip or budgeting for your monthly commute requires a precise understanding of fuel expenses. Our Fuel Price Calculator helps you estimate exactly how much you will spend on petrol or diesel based on current market prices and your vehicle's performance.
How the Calculation Works
To determine the total cost of your journey, we use the following physical and mathematical relationship:
- Total Fuel Needed: (Distance / 100) × Fuel Efficiency
- Total Trip Cost: Total Fuel Needed × Fuel Price
- Cost Sharing: Total Trip Cost / Number of Passengers
Example Calculation
Imagine you are driving from Sydney to Canberra, a distance of approximately 280 km. Your car consumes an average of 8.5 Liters per 100 km, and the current fuel price at the station is $1.95 per Liter.
- Fuel Volume: (280 / 100) * 8.5 = 23.8 Liters
- Total Cost: 23.8 * $1.95 = $46.41
- Split Cost: If 3 friends are traveling, the cost is only $15.47 per person.
Tips to Reduce Fuel Consumption
Fuel efficiency isn't just about the car you drive; it's also about how you drive it. Consider these factors:
- Maintain Tire Pressure: Under-inflated tires increase rolling resistance, which forces the engine to work harder.
- Remove Excess Weight: Carrying heavy items in the trunk increases the energy required to accelerate.
- Smooth Driving: Rapid acceleration and hard braking can increase fuel consumption by up to 30%.
- Check Aerodynamics: Roof racks and open windows at high speeds create drag, reducing efficiency.
