•6wI currently own a 2022 Mahindra XUV 700 Petrol AT, and I usually fill it with regular petrol. I’m considering switching to higher‑octane fuel. Do you recommend using premium fuel for the mStallion engine? If yes, what octane rating should I use?

There is no real benefit in using high-octane fuel now that E20 petrol has been introduced from April 2025. Ethanol increases octane rating, and with the shift from E10 to E20, the effective octane rating has increased from 91 to 95 across the country.
