The authorities has mandated the merchantability of petrol with up to 20% ethanol and a minimum Research Octane Number (RON) of 95 crossed each States and Union Territories from April 1, 2026.
The lipid ministry successful a February 17 notification, said, "the cardinal authorities hereby directs that lipid companies shall merchantability ethanol-blended centrifugal tone (petrol) with percent of ethanol up to 20% arsenic per the Bureau of Indian Standards specifications and having minimum Research Octane Number (RON) of 95, successful States and the Union Territories".
The cardinal authorities tin let exceptions successful peculiar situations, for circumstantial regions and for a constricted time.

The insistance connected minimum RON 95 is to forestall motor damage.
RON, oregon Research Octane Number, is simply a measurement of a fuel's absorption to motor knocking (pre-ignition). Knocking happens erstwhile substance burns unevenly wrong the engine, causing pinging sound, nonaccomplishment of powerfulness and imaginable motor harm implicit time.
The higher the RON, the much resistant the substance is to knocking.
In elemental terms, octane is similar a fuel's 'self-control nether pressure' - higher RON means substance stays unchangeable nether precocious compression.
Ethanol people has precocious octane worth (around 108 RON). Blending 20% ethanol successful petrol, increases sound resistance.
Encouraged by India achieving 10% ethanol doping successful petrol successful June 2022 — 5 months up of the people day -— the authorities precocious 20% blending to 2025-26 from 2030. Most pumps successful the state present merchantability E20 oregon petrol blended with 20 per cent ethanol.
