Fuel Saving Tips
How to improve fuel efficiency?
Maintain steady speeds between 60–80 km/h on highways, keep tyre pressure at recommended levels, avoid aggressive acceleration and braking, and service your vehicle regularly. These steps can improve mileage by 10–20%.
Petrol vs diesel — which is cheaper per km?
Diesel is usually cheaper per litre and diesel vehicles deliver better mileage, making diesel more economical per km for long-distance driving. However, diesel cars have higher purchase cost and maintenance.
Is CNG worth it?
CNG is significantly cheaper per km than petrol or diesel. If you drive more than 1,500 km per month in a city with good CNG infrastructure, a CNG kit can pay for itself within 1–2 years.
