Drive between 45-60 km/h for bikes and 60-80 km/h for cars. Avoid rapid acceleration and sudden braking.
Under-inflated tyres increase rolling resistance and reduce mileage by up to 10%. Check pressure every 2 weeks.
Clean air filters, good spark plugs, and timely oil changes can improve fuel efficiency by 5-15%.
Every extra 50 kg can reduce mileage by 2%. Remove unnecessary items from the boot and roof rack.
Driving in a higher gear at low RPM reduces fuel consumption. Avoid revving the engine unnecessarily.
If stopped for more than 30 seconds, switch off the engine. Idling wastes 200-300 ml of fuel per hour.
AC can reduce mileage by 10-15%. Use fan mode at low speeds and AC only on highways when needed.
Avoid peak hours and congested routes. Use navigation apps to find the shortest, least-traffic path.
An EV typically costs ₹3-5 lakhs more than its petrol equivalent. At current fuel prices, you can recover this premium in approximately 3-5 years if you drive 15,000+ km annually. With rising petrol prices and falling electricity tariffs, the payback period is shortening every year.
A: Fuel cost is calculated by dividing the trip distance by your vehicle mileage to get the fuel required, then multiplying by the current fuel price per litre (or kg for CNG).
A: CNG is generally the cheapest per km, followed by diesel, and then petrol. However, CNG availability is limited to certain cities, and diesel vehicles cost more upfront.
A: Maintain steady speed, keep tyres properly inflated, service your vehicle regularly, reduce excess weight, use the correct gear, and avoid unnecessary idling and aggressive driving.
A: Yes, diesel engines are more fuel-efficient and deliver better torque, making them ideal for highway driving and long distances. The higher upfront cost pays off if you drive more than 20,000 km per year.
A: If your daily commute is under 100 km and you have home charging, an EV can save you ₹4-6 per km in running costs. For frequent highway trips or lack of charging infrastructure, a petrol/CNG car may still be more practical.
A: Yes, petrol and diesel prices are revised daily at 6 AM based on international crude oil prices and exchange rates. CNG prices are revised less frequently by individual state gas distribution companies.
