resumeIn brief
Ethanol can be involved in gasoline mixtures of different composition. The E85 should not be taken as an ordinary substitute for gasoline in any model.
Useful to know
E10 is a mixture of 10% ethanol and 90% gasoline as described by the AFDC. In the E85 in the American context, the ethanol share indicated is 51-83% by season and place. Therefore, the E85 name does not prove exactly 85% in every delivery. [1]
AFDC connects the E85 with flexible-fuel cars designed for such blends. External similarity to a regular petrol car does not prove compatibility. [1]
Practically checked the exact guidelines for its model and the market for which it was manufactured. A common text for American approval is not a permit to charge a random European car with a high-ethanol mixture.
It is a common mistake to watch only that both fuels are used in spark-ignition engines. Different composition requires a suitable fuel system and management. The source explains the categories; it doesn't identify your specific car just by appearance.
