What kind of gas should I put in my Honda Accord 2011?

Added (1). Diesel or Ethanol? I don't know much about the different types of gasoline

The kind of gas that's recommended by the manufacturer of the vehicle. When in doubt, try READING the owner's manual.

Your owner's manual will tell you. I believe 87 octane unleaded is fine in this car. Do not use E85 ever, or any octane lower than 87 of regular gas. E85 will ruin your fuel system because it is corrosive and lower octanes than 87 will make the performance degrade severely.

87 Octane Regular. There's no benefit whatsoever in using any higher octane fuel.

For more power, always use diesel

What kind of Accord do you have?
In UK there are Accord Diesel, therefore use Diesel fuel.
In US Accord use regular gasoline, unleaded fuel, 87 octane or higher.
