What is good fuel efficiency?

For petrol cars, 15-20 km/l is good. For diesel, 18-25 km/l is good. Hybrid vehicles can achieve 25+ km/l. Electric vehicles measure efficiency in km/kWh.

How do I calculate my car's actual mileage?

Fill your tank completely, note the odometer reading. Drive normally until you need fuel again. Fill up again and note the liters added and new odometer reading. Divide km driven by liters used.

Does AC affect fuel consumption?

Yes, AC can increase fuel consumption by 5-15% depending on the vehicle, outside temperature, and AC settings. At highway speeds, AC is more efficient than open windows.

What is a Fuel Cost Calculator?

A fuel cost calculator estimates how much fuel and money you'll need for a trip. It considers your vehicle's fuel efficiency, the distance you're traveling, and the current fuel price. This helps you budget for road trips and compare the cost of different vehicles.

Fuel Cost Formula

Total Cost = (Distance ÷ Fuel Efficiency) × Fuel Price

Fuel Needed = Distance ÷ Fuel Efficiency (in km/L or MPG)

Tips to Reduce Fuel Costs

Maintain steady speeds: Avoid aggressive acceleration and braking.
Keep tires inflated: Underinflated tires increase fuel consumption by 3-5%.
Remove excess weight: Every 50 kg of extra weight increases consumption by 1-2%.
Use cruise control: On highways, cruise control maintains optimal fuel efficiency.
Regular maintenance: Clean air filters and fresh oil improve fuel efficiency.
Plan routes: Shorter and less congested routes save fuel.

Frequently Asked Questions

Good fuel efficiency varies by vehicle type: Hatchbacks: 15-22 km/L, Sedans: 12-18 km/L, SUVs: 8-14 km/L, Electric vehicles: equivalent of 50+ km/L. Higher km/L numbers mean better efficiency.

Fill your tank completely, note the odometer reading. Drive normally until you need to refuel. Fill the tank again and note the litres filled and new odometer reading. Divide distance driven by litres filled. Example: 500 km ÷ 35 L = 14.3 km/L.

Yes, running the AC can increase fuel consumption by 5-15% depending on conditions. However, at highway speeds, AC is more efficient than opening windows (which creates drag). In city driving, opening windows can be more fuel-efficient.
