A detailed, side-by-side analysis for all three major vehicle types.
Whether you drive a compact petrol car, a diesel SUV, a CNG sedan, or a modern electric vehicle (EV), understanding fuel consumption is essential to saving money and reducing emissions. Our Fuel Consumption Calculator helps you track real-world mileage, compare fuel types, and find ways to drive smarter and more efficiently.
Fuel consumption measures how efficiently your vehicle converts fuel or energy into distance traveled. It directly affects your running costs, carbon emissions, and overall performance. A few key metrics are commonly used worldwide:
Accurately measuring your car’s fuel use helps you understand your true costs, plan longer trips, and identify maintenance issues early.
Each fuel type—petrol, diesel, CNG, and electricity—behaves differently in terms of cost, performance, and energy output. Let’s break it down:
Petrol cars are smooth and widely available, but often less fuel-efficient compared to diesel or CNG vehicles.
Diesel engines deliver higher torque and better mileage—ideal for long-distance travelers.
CNG offers cleaner emissions and lower costs but requires frequent refueling and reduces boot space.
Electric vehicles use no fuel and produce zero tailpipe emissions. Their efficiency is measured by energy usage.
Our online calculator helps you easily measure your car’s real-world fuel efficiency and total running cost:
You can also compare fuel types side by side to determine the most economical and eco-friendly option for your driving habits.
Even small changes in driving behavior can improve mileage by 10–20%. Try these expert-recommended habits:
Reducing fuel consumption doesn’t just help your wallet—it helps the planet. Improved efficiency leads to:
Use the “Full Tank Method”: fill your tank, reset your trip meter, drive normally, then refill again. Divide the distance traveled by fuel added to get your mileage.
For long-distance drivers, diesel remains efficient. But with stricter emission norms, petrol and hybrid cars are becoming more cost-effective for city use.
Yes, electricity is cheaper per kilometer compared to fuel, and EVs have fewer moving parts—meaning lower maintenance costs.
Yes. For hybrid cars, input the average fuel use shown on your vehicle dashboard or from your manufacturer’s data.
Tracking your vehicle’s fuel efficiency is the simplest way to reduce costs and environmental impact. Whether you drive petrol, diesel, CNG, or electric, our Fuel Consumption Calculator helps you make smarter, greener choices every day.
