The government responds to questions about why E20 is not cheaper than E10 or pure petrol and why petrol pumps cannot offer all grades together. It says E20 petrol costs more to produce than pure petrol at current crude oil prices, which affects retail pricing. On performance, the government acknowledges that some vehicles may experience a small (about 3–5%) dip in fuel economy when using E20. It argues this is offset by factors including higher octane characteristics, cleaner combustion, and reduced reliance on crude oil imports. The government also addresses concerns about vehicle compatibility, stating that E20 is compatible with older vehicles. In addition, it says that providing multiple petrol grades—such as pure petrol, E10, and E20—at the same fuel station is not practical from an operational standpoint. Overall, the government’s position is that cost and infrastructure constraints shape how fuel grades are marketed and priced, while performance impacts are limited and benefits are expected from fuel quality and supply-chain considerations.
