What is the air-fuel ratio for liquid petrol

  1. I've been wondering this for a while, I can't figure it out though, it's easy enough for figure it out for petrol vapour, but the problem is with liquids
    when Googling it, the ratio 14.7:1 is common, but it seems as if that's for pure Octane.
    if someone could also include the method of calculating it, that would be great!

    edit: at room temperature :)
    edit2: looks as if this has been asked before, sorry about posting this :) I should have searched
