Indian government considering mandatory chloride limits in E20 gasoline, BIS
India's government is considering making chloride limits in E20 gasoline mandatory, aiming to tackle worries from carmakers about fuel quality.
Right now, the standards are voluntary, allowing less than 3 parts per million (ppm) of chloride, but the government is considering making these rules mandatory.
The Bureau of Indian Standards (BIS) is leading the charge to make sure ethanol-blended gasoline across India gets a quality boost.
Automakers link E20 contamination to failures
Automakers have flagged elevated chloride levels and excess moisture in E20 gasoline, linking the contamination to a rise in failures of certain vehicle parts.
Tests have backed up their concerns, showing excess chloride in fuel tanks.
With India hitting its 20% ethanol blending goal way ahead of schedule, the focus has shifted to making sure this greener fuel doesn't damage cars, and that it stays reliable as policymakers and industry discuss the possibility of moving toward higher ethanol blends in the future.
