Correct fuel for Suzuki Ignis Sport??

[Low Pro]

So the story goes bought a lovely little Ignis sport, was very happy with purchase however the book says RON 98... fine, however the book also says Ethanol levels have to be low, and I am so confused on what to fill up with. Tesco momentum (which is RON 99 but what is the Ethanol rating?) Or Shell V power but no idea which RON this is?! Or do I just buy standard fuel and put in a octane booster. Help ideas please... (sorry for poor grammar)

Thanks for the help, did find the Shell stuff was giving me better performance in terms of engine revs, but with the cold winter air might just use standard 95.
