Despite government assurances, concerns remain about the rapid introduction of E20 petrol in the market. Critics argue that the existing automotive infrastructure and older vehicles are not fully prepared to handle 20% ethanol mixes, potentially leading to maintenance issues and higher costs for vehicle owners.
Some vehicle owners have reported decreased mileage beyond the government-stated 3-5%, and there are fears about long-term engine damage, especially in models manufactured before widespread ethanol compatibility. These concerns have not been fully addressed with comprehensive third-party studies.
The lack of widespread public education about E20, and limited availability of 100% petrol as a premium alternative, could disproportionately affect rural and low-income populations. Critics suggest a more gradual transition with clear guidelines and subsidies might mitigate potential economic burdens.
Until more conclusive evidence and infrastructure readiness are assured, skepticism towards E20 adoption remains.
