About this question

Why in news

Leaked emails contradicting SIAM's public retraction of its fuel contamination complaint surfaced days after the petroleum ministry assured the public that E20 ethanol-blended fuel was safe, raising questions about industry dependence on a dominant government fuel buyer.

Why for UPSC

The "Not Correct" format is well suited to testing the accelerated-timeline detail (2030 advanced to 2025-26, not deferred), a fact easily inverted by a hurried reader and therefore a genuine test of careful reading and retention.

Prelims summary

India's E20 rollout was accelerated from a 2030 target to 2025-26 and has been the sole petrol at pumps since April 2026; SIAM's contamination complaint (chloride up to 570 ppm, moisture up to 13,000 ppm against 3 ppm/3,000 ppm limits) was withdrawn despite leaked data supporting it.
