Times the fuel came up, it has been tested by various car
magazines over here, they put different cars on a
power-absorption roller and there was IIRC nothing that couldn't
be explained with measuring tolerance.
They compared with the fuel quality outlined by the manufacturer.
Sadly RON/ROZ are not directly comparable, so I don't know which
quality 95 RON would be over here and if it's in the spec for
Foci over here.

IMHO, you'd need a reprogrammed ECU or so to take advantages from
the fuel. It's easy to fool oneself, only a power-absorption
roller would show if there's a real gain.
Sure anyone who thinks he could benefit from it should simply
test it out and see for himself and his car. It doesn't cost you
a fortune to fill up your car once or twice with it.
Your fuel consumption is 7.2-7.8 l/100km, never got this out of
my Focus (2.0l manual), I'm lucky to get below 9.0 l/100km (26
mpg), with some care. As soon as you drive >160 km/h (>100 mph)
the Focus starts guzzling fuel, >200 km/h (>125 mph) an you can
watch the fuel gauge fall.;( On the other hand you aren't really
annoyed about a partially speed limits on your way, it helps to
keep the average fuel consumption in acceptable regions.
Of course, if the highway is empty enough, which is rare enough,
the weather fine, mostly it's not and no speed limit, you should
have more luck with that, it's nice letting the Focus run. DON'T
look at the fuel gauge... ;-)
