Abstract
Methods and systems are provided for adjusting operation of a plug-in hybrid electric vehicle responsive to a seasonal grade of the fuel available in the vehicle's fuel tank. If the seasonal grade of fuel in the fuel tank does not correspond to the seasonal grade of fuel mandated during the time of engine operation, a fuel injection amount is adjusted to compensate for differences between seasonal grades of a fuel.
