Experts Discuss Accuracy of Car Mileage Measurement Amid E20 Petrol Use
Union Minister Nitin Gadkari stated that accurate car mileage measurement requires company-authorised dealer machines, as onboard trip computers estimate fuel efficiency using engine data and can be imprecise. Independent tests show dashboard readings often overstate mileage by 2 to 15 percent. The rollout of E20 petrol, containing 20% ethanol with lower energy density, has led to real-world mileage drops of 3 to 6 percent, which dashboards may not reflect accurately. The tank-to-tank method remains the most reliable for measuring fuel economy.
