I just bought a used Civic and I suspect that it needs 89 or 93 octane grade, but it didn't come with the owner's manual so I can't check. Obviously I don't want to pay for the more expensive grade if I don't have to (but I don't want to mess up my engine either).
Anyone know?
That should be 91* not 93.
