Why calculate fuel cost?
- Splitting Bills: If travelling with friends, knowing the exact fuel contribution is fair.
- Route Planning: Sometimes a longer route with better roads (highway) gives better mileage than a shorter route with city traffic.
- Comparisons: Compare cost of driving vs taking a train or flight for long distances.
Pro Tip
Always keep a buffer of 10% in your fuel budget for traffic jams, detours, or AC idling.
Frequently Asked Questions
How to calculate fuel cost for a trip?
Formula: `(Distance / Mileage) * Fuel Price`. Example: 500km trip, car gives 20km/l, petrol ₹100/l. Cost = (500/20) * 100 = ₹2,500.
What determines my car's mileage?
Driving style (aggressive acceleration reduces mileage), tyre pressure, AC usage, and traffic conditions all affect real-world mileage.
Does AC reduce mileage?
Yes, using the AC constantly can reduce fuel efficiency by 10-20% depending on the car's engine power.
How to improve fuel efficiency?
Drive at a constant speed (45-55 km/hr in city), avoid sudden braking, keep tyres inflated correctly, and service the engine regularly.
Petrol vs Diesel cost?
Diesel cars usually offer higher mileage (20-25 km/l) than petrol cars (15-18 km/l) and diesel is slightly cheaper, putting the cost per km lower.
What is 'Tank-to-Tank' method?
The most accurate way to check mileage. Fill tank to full. Reset trip meter. Drive. Fill again to full. Mileage = Km Driven / Fuel Litres filled.
Is electric car cheaper for road trips?
Yes, significantly. EV cost per km is ₹1-₹2, whereas petrol cost per km is ₹6-₹8.
Can I split fuel cost with friends?
Yes, just divide the 'Total Trip Cost' result by the number of passengers using this tool.
Should I use premium petrol?
Unless you have a high-performance engine that requires high-octane fuel, normal petrol works fine and saves money.
How does car load affect cost?
More weight = Engine works harder. A fully loaded car with 5 passengers + luggage changes mileage significantly compared to a solo driver.
