E85 fuel contains up to what share of ethanol by volume?
- A.20 per cent
- B.50 per cent
- C.85 per cent
- D.100 per cent
Correct answer
Explanation
The correct answer is 85 per cent. E85 is a blend of petrol and ethanol in which ethanol forms up to that share by volume. In this notation the letter E denotes ethanol while the number indicates the proportion of ethanol present in the fuel, which is why E100 refers to a fuel consisting predominantly of ethanol. Option A is wrong because that share corresponds to E20, and the Ministry specifically warned that a vehicle compatible with E10 or E20 is not thereby suitable for E85. Option B is wrong as no blend of that name figures in the notification. Option D is wrong because a share of that size describes E100, which the amendment added to the certification provisions alongside E85 rather than being the definition of E85 itself. Flex fuel vehicles handle a range of such blends from a single fuel tank.
