E20 may cut mileage by up to 5 pc but offers cleaner combustion, energy security benefits: Oil Min
NEW DELHI, July 10 (PTI): Petrol blended with 20 per cent ethanol (E20) can reduce fuel economy by 3-5 per cent in some vehicles, the Oil Ministry said on Friday, but argued the impact is outweighed by benefits, including a higher octane rating, superior anti-knock characteristics, faster combustion, better pickup, smoother acceleration, cleaner engine operation, and lower lifecycle carbon emissions.
In a detailed question-and-answer document issued to counter criticism of the Ethanol Blended Petrol Programme, the Ministry of Petroleum and Natural Gas said E20 was a “cleaner, higher-quality and more efficient fuel” than E10 or pure petrol and had been rolled out only after years of scientific testing, consultations with automobile manufacturers and the expansion of domestic ethanol production.
The ministry rejected concerns that the programme had been implemented too quickly, saying India’s ethanol blending initiative dates back to pilot projects launched in 2001, with 5 per cent blending introduced in parts of the country by 2006.
