Explained: Why is India moving to RON 95 alongside E20 petrol?
The introduction of RON 95 alongside E20 is intended to stabilise combustion as ethanol content rises. RON, or Research Octane Number, measures a fuel’s resistance to knocking. Higher octane fuel burns more smoothly under pressure and allows engines to maintain optimal ignition timing instead of compensating for instability.
