Looks like the US manuals specify 93: https://www.camaro6.com/forums/showp...3&postcount=11

I don't know if the EU Camaros come with a different base map than the US and Canadian models. Or if it is just a Would be cool to find out. Or maybe it is just a convenience thing.

Most places carries 95 RON, E85 and Diesel. The only place I know of that has higher octane is Shell, who has the V-Power 100 (RON).But it comes out at around 7.35 USD per gallon.

I see, it's 91 US and that should work, my owner's manual has the same info. Plus the real premium stuff is super expensive in Europe. Actually, gas is way more expensive there overall, but that's another tangent and I won't hijack the thread.

Not sure 98 RON or V-Power would make any performance difference in your case, and that kind of cost is hard to justify. I only ever use 93 US, but then I have a supercharger (ie I forfeited my warranty), and don't want to risk any issue by getting just the bare minimum required.
