3.5 V8 Compression Ratio

[malrv1]

Hi Will a 9.35:1 3.5 V8 run on our 91 RON unleaded OK?? I know in the UK there standard unleaded is 93 RON.

The filler cap sticker on my hi-comp 4l says premium,,,:(

I run mine on it without issue if it pings just change the timing slightly
It doesn't perform as well as the higher octane fuel but it works fine

Mine ran fine on 91, but with 350,000KM on it, I doubt the compression was as high as it was when it left the factory...:D
