XP100 vs ETHANOL 100: Different Fuels, Similar Names
Do not confuse IndianOil XP100 petrol with ETHANOL 100. Compare the product names, vehicle requirements and dispenser checks before refuelling.
Key Takeaways for Indian Motorists:
- XP100 and ETHANOL 100 are distinct IndianOil products.
- The number 100 does not mean the same thing in both names.
- Confirm the exact product and your vehicle's fuel approval.

Why the names are easy to confuse
Both names appear in IndianOil's product range and contain 100. Someone looking for "100 petrol" can therefore find information about two different fuels.
IndianOil's XP100 page describes a 100-octane petrol product. Its separate ETHANOL 100 launch announcement concerns an ethanol-based automotive fuel and discusses flex-fuel vehicles. These are not interchangeable product names.
What should be compared?
| Question | XP100 | ETHANOL 100 |
|---|---|---|
| What should I ask for? | XP100 petrol, using its full name | ETHANOL 100, using its full name |
| What does the product information describe? | A 100-octane petrol grade | An ethanol-based fuel |
| Does the name mean zero ethanol? | The current blend needs separate confirmation | No |
| What vehicle check matters? | Applicable petrol and octane requirements | Explicit approval for that fuel |
The table identifies the questions to resolve. It is not approval to use either product in a particular vehicle.
Is E20 compatibility the same as flex-fuel capability?
Do not assume that approval for E20 extends to much higher ethanol blends. Maruti Suzuki's flex-fuel prototype announcement describes additional fuel-system and engine-management engineering for that prototype. A prototype announcement also does not establish the specification of a car already in your garage.
Check the vehicle documentation for the exact fuel you intend to buy. If it is unclear, obtain manufacturer guidance before filling.
A dispenser checklist
- Read the complete product name on the dispenser.
- State that exact name when speaking to the attendant.
- Check that the receipt identifies the intended grade.
- Resolve any mismatch before refuelling begins.
A station directory may list several products sold at one location. The correct station address does not by itself identify the correct nozzle.
How can I avoid misleading searches?
When seeking XP100, include XP100 rather than only "100 fuel" in your enquiry. When seeking zero-ethanol petrol, ask about ethanol content explicitly as well. The E0 Finder map can help locate leads, but direct product confirmation remains necessary.
If a search result describes ETHANOL 100 while your goal is E0, return to the product identity question. Similar wording is not evidence of equivalent fuel.
