There are a lot of misinformation regarding octane rating in India and also about premium fuels.
- India: India's ordinary and premium gasolines are of 91 RON. The premium gasolines are generally ordinary fuels with additives, that do not really change the octane value. Two variants, "Speed 93" and "Speed 97", were launched, with RON values of 93 and 97. India's economy-class vehicles usually have compression ratios under 10:1, thus enabling them to use lower-octane gasoline without engine knocking.
