I don't agree. The GX engine is standard 10:1 and it uses normal 93 here in ZA. My VW 1.8i engine is 10.5 : 1.Actually all VW engines are 10.5 : 1 and it runs fine on 93 and 95 octane. I think it is from 11:1 that one must go 95 and higher octane to prevent detonation. I know of a guy that build a performance A15.He used a GX head that was skimmed to the max. No detonation and I think he is running 95 octane.
