Can I use high octane fuel in my 2002 Ford Focus?

The handbook for my July 2002 Ford Focus states there is no point in using petrol of a higher octane than 95. Presumably fuel constituents have changed considerably over the last 11 years. So is the handbook still correct?

Using Shell V-Power Nitro Plus will give you 5-10 per cent more power, keep the engine fuel system clean, and give more torque at lower revs allowing you to change up earlier and achieve a small improvement in economy. Your handbook was written long before V-Power Nitro Plus was developed.
