XP100 vs E20 - is it worth switching?
Comparing XP100 vs E20? XP100 is ethanol-free but costs much more per litre. This calculator does the honest math on whether any mileage gain actually pays for the premium.
XP100 vs E20 - what is XP100, and is it really ethanol-free?
XP100 is IndianOil's 100-octane premium petrol, and it is currently the only widely sold ethanol-free petrol in India. Other "premium" fuels - XP95, BPCL Speed 97, HPCL Power - are higher octane but still contain about 15-20% ethanol, so they are not an escape from E20-style blending.
Is there an XP100 equivalent in HP (HPCL)?
Short answer: no true ethanol-free equivalent. Hindustan Petroleum's Power / Power 95 is a premium high-octane grade, but like most premium pumps it still contains ethanol. If your goal is zero ethanol, IndianOil XP100 is the widely sold option today - not HP Power, BPCL Speed 97, or Shell V-Power. Compare grades on our ethanol-free petrol finder.
The honest verdict on mileage
Higher octane (like XP100) mainly benefits high-compression / performance engines. In a normal commuter car or bike, you may recover a little of the E20 mileage loss, but rarely enough to offset a price gap of roughly ₹60 per litre. Where XP100 can make sense: peace of mind for a cherished older vehicle, or genuine performance cars designed for high octane.
