Octane rating of petrol in india

Solution (By Examveda Team)

Octane rating refers to a fuel's ability to resist 'knocking' or 'pinging' during combustion, caused by the air/fuel mixture detonating prematurely in the engine.

In India, the commonly available petrol types are Regular (Unleaded) and Premium petrol.

Regular petrol has an octane rating of about 91, which is suitable for most standard vehicles.

Premium petrol variants like "Speed", "Power", or "XP95" have higher octane ratings ranging from 91 to 93, and even up to 95 in some branded fuels.

Higher octane fuels are generally used in high-performance engines to ensure better efficiency and reduced engine knocking.
