I have a 2012 Honda Civic, what gas does it take??

Other answer:

87 octane gasoline only. Your Civic is neither a premium required or recommended vehicle. The use of gas with a higher octane level than 87 would neither give you better performance or fuel economy, it would simply be a waste of cash.
It takes petrol/gasoline. You do not have a Ferrari LaFerrari with an insanely high compression, you have a moms car. Spending extra money on fuel is pointless, I don't care if your daddy had an Accord and said, "I use 93 octane because it's better for the engine". Because it isn't.
Regular, unless it's an Si.
It takes petrol
Gray Area:
87 octane will do
