Can someone tell me what's the safest compression ratio where I don't need to use higher octane fuel, I read 10.5.1 in a haynes performance manual book?

Today fuels are so different than at the time they wrote performance books.. Higher octane is always better above 10:1, mines now at 11:1 and on 95 runs fine but not as smooth as with 100 ron.I use additives tough.

I'll aim to keep it around 10:1 I think then, just to be on the safe side.
