Three months ago, the E20 rage on social media spilled over to Jantar Mantar, with claims that the fuel mix of 20% ethanol and 80% petrol corroded vehicle engines and reduced mileage. The government paused higher blending and even discussed bringing back E10, the 10% ethanol blend, to prevent engine damage in older vehicles. The crowd at Jantar Mantar on July 20 was a diverse coalition, organic, forcing the government to engage with the CJP.
