2012 Civic hatch - can it run 91

[C.I.SIvic]

Hi folks, been a while since I've been on here since I let my teg go. Anyway I thought I'd ask the brains trust about this one. I have a 2012 civic hatch (RA18 bog stock). Since it's UK built, the fuel specifies a minimum 95 RON fuel. I've dug and dug here and there and it looks for all intents and purposes identical to the aussie (Thai built) sedan RA18 motor which takes 91.

Keen to save a few cents on the daily beater.

So question is, can I reflash to run 91?

Run 98
Run anything less for pinging and premature o2 sensor death

as above said ^^

just fill up with 98

i use to fill up with 91 / 95 but when filled up with 98 i got better petrol kms out of a full tank and much cleaner

What the user manual say? Use nothing less than what it recommends.
