E20 petrol reduces mileage by 2-6%, no engine failures: Gadkari
UPSC / SSC current affairs note · IR
Why in news
Union Minister Nitin Gadkari informed Parliament that E20 petrol can reduce vehicle mileage by 2-6%, but extensive testing shows no engine failures. This comes amid criticism over fuel economy and compatibility concerns as India pushes ethanol blending.
Background
India's ethanol blending programme started as a pilot in 2001, with E5 introduced in 2006. Blending rose from 1.53% in 2013-14 to higher levels after infrastructure buildup. E15+ has been used for over 3.5 years, E19-E20 for over 2.5 years.
Key facts
E20 petrol (20% ethanol, 80% petrol) can reduce vehicle fuel efficiency by 2% to 6% depending on vehicle category and age.
Extensive testing by ARAI, SIAM, and IOCL found no engine failures due to E20.
E20 offers improved acceleration, better ride quality, and about 30% lower carbon emissions compared to E10.
Tests covered BS-III, BS-IV, and BS-VI petrol two-wheelers and four-wheelers using standard and customised protocols.
Automobile manufacturers continue to honour warranty claims for vehicles using E20.
The Ethanol Blended Petrol (EBP) Programme is implemented through a phased consultative process involving NITI Aayog, OMCs, automakers, ARAI, SIAM, IIP, and other institutions.
India's ethanol blending started as a pilot in 2001; E5 was introduced in 2006.
Ethanol blending was about 1.53% in 2013-14 and has increased steadily.
E15+ petrol has been in widespread use for over 3.5 years; E19-E20 for over 2.5 years.
