if forced induction, run premium. Even if it is designed for 87, it will run better and stronger on premium. I am sure Jaeger could do an experiment with his Sonata 2.0T and a dyno/ fuel mileage calc. My Saab certainly loved premium when not tuned, and was rated at 87 octane.

Also never ever put ethanol in a high compression or forced induction engine, unless it is tuned for it. Will eat injectors after a while and causes turbo cars to suck.

V Power rocks, only gas I fill the picky Saab and super picky Alfa with. No ethanol 91 octane.

Depends on if your injectors are compatible with ethanol.  I know on my 300zx, the early style injectors were not and would die rather quickly, but later style injectors are.  How does ethanol cause turbo cars to suck? If you are tuned for 94 ethanol, it makes a nice difference on power / torque versus the non-ethanol 91.  But I would only run it if you are tuned for it.

like I said, only run it if you are tuned for it...like I said. Otherwise agree.

So this thing drinks premium and still uses semi independent rear torsion beam suspension?

The Owners Manual says 87 Octane (it's direct injection) the Owners Manual also says that you can use higher Octane for more power.

Ford Canada website lists premium as recommended for the Fiesta ST. However, in the technical specs provided to media, 87 octane is the minimum. 91+ is only recommended.

The Owners Manual (and the Fiesta ST Supplement) don't use the word "recommend". They both say 87 Octane and they both say that you can run higher Octane for more power.

FRS?

200 horses, RWD.....no problem with premium in that.

Your money... FRS or Fiesta ST?

FRS...no ifs, and or butts about it. It would be a great little toy for the weekends. While I really like the little Fiesta....the FRS is rwd, that makes it inherently better. Not saying the Fiesta is a POS, but the FRS would be more fun, IMO anyways.
