Report: Switch from E10 to E20 fuel leads to a mileage dip of 2-6%
| Fuel Type | Ethanol Content | Average Mileage Impact | Explanation |
|---|---|---|---|
| E10 | 10% | Baseline | Standard petrol-ethanol blend |
| E20 | 20% | 2-6% lower mileage | Ethanol has lower energy density than petrol, leading to reduced fuel efficiency |
Why Does E20 Fuel Cause Mileage Dip?
- Lower Energy Density: Ethanol contains less energy per litre compared to petrol, so higher ethanol blends reduce the overall energy content of the fuel.
- Engine Compatibility: Not all vehicles are optimized for E20 fuel, which can affect combustion efficiency.
- Fuel System Adjustments: Vehicles may require tuning or modifications to handle higher ethanol blends effectively.
Impact on Indian Drivers and Automakers
| Stakeholder | Impact & Considerations |
|---|---|
| Vehicle Owners | Slightly reduced mileage; need to check vehicle compatibility with E20 |
| Automakers | Need to certify and possibly modify engines for E20 compatibility |
| Fuel Retailers | Infrastructure upgrades to handle higher ethanol blends |
| Environment | Reduced carbon emissions despite mileage dip |
Government’s Ethanol Blending Roadmap
| Year | Target Ethanol Blending Percentage |
|---|---|
| 2023-24 | 10% (E10) |
| 2025-26 | 20% (E20) |
| 2030 | 27% (E27) |
The government is pushing for higher ethanol blending to meet sustainability goals and support the agricultural sector.
Tips for Drivers Using E20 Fuel
- Verify if your vehicle is compatible with E20 fuel.
- Monitor fuel efficiency regularly.
- Follow manufacturer guidelines for fuel use.
- Consider regular engine maintenance to optimize performance.
