India targets 20% ethanol blending (E20) in petrol by 2025-26 under National Biofuel Policy 2018, advanced from original 2030 target
GK and monthly revision
The E20 transition: fuel for debate
The article examines widespread consumer complaints about vehicle performance issues — clogged injectors, damaged fuel pumps, and contaminated petrol — coinciding with India's accelerated E20 (20% ethanol blending) rollout. It analyses competing claims from automakers, oil companies, and experts on whether ethanol blending is the root cause or if fuel quality and supply chain gaps are responsible. The debate highlights implementation challenges of India's ethanol blending programme, a key component of the National Biofuel Policy and energy security strategy. For exams, this covers energy policy, environmental commitments, and infrastructure readiness.

Exam-ready takeaways
Consumers report clogged fuel injectors, damaged fuel pumps, and petrol contamination since E20 rollout began in phases from April 2023
Ethanol's hygroscopic nature absorbs water, risking phase separation in fuel tanks if storage and handling infrastructure is inadequate
Automakers (SIAM) confirm BS-VI vehicles are E20 material-compatible but flag concerns over fuel quality consistency at retail outlets
Government maintains E20 is safe; Oil Marketing Companies (IOCL, BPCL, HPCL) mandated to ensure water-free ethanol supply chain
