    F30 - 320i gas preference? 89 Octane or higher

    Salesman at the dealership advised using at least 89 octane, never 87, stating the engine may act up, etc.

    Curious and looking for advice on what the norm/best is for the 2.0 liter 4 cyl in the 2016 320i.

    Thanks!

    I highly recommend against 87. Put some by accident once and sure enough, had a CEL soon after. 89 may be ok, but the difference to 91 is usually small that I would go with 91 esp. if you drive aggressively.
