another factor is that likely your local gas stations have all converted to 10% ethanol in the cheap stuff and 5% in the midgrade.
Ethanol and the Focus go together like crap on a stick. Even if I wasn't running a 91 tune, I'd probably be buying at least 89 grade to minimize ethanol stuff going through my engine <_<
