These should help. Seafoam the car, check the tire pressure, change spark plugs(wires if necessary). See how mileage is after that and you can go from there. If still crappy I'd say new O2 sensors depending on how old the car.

Seafoam is an additive that can be put in the pcv, crank, and gas to help clean and knock off sludge.(Found at all local auto parts store) Eh...I would say that you don't need to use the seafoam on the pcv and in the oil, because its such a new car, but it would be helpful to pour in the gas tank (just follow instructions).

Also, Don't know maintenance intervals on a focus but I would definitely recommend changing the fuel filter and air filter. I know on my year stangs you change the fuel filter every 30k. Find out the maintenance intervals and do all that is required. Other than that it would help to check air pressure on the tires and check to see the spark plugs are still good.

Since the car is so new I would bet on the filters and possibly on the fact she may be driving differently or in different conditions lately. Good luck and if what is said in this thread doesn't help put an update and we can go from there. ;)

Its probably her imagination.

Maybe she is doing more in town driving than usual. or driving harder than usual

How much worse is the gas mileage ?
are the tires properly inflated?
any unnecessary weight in the trunk?
she also can be getting crappy gas from a certain station/.

glad to hear you got it fixed. Hope you didn't waste your time at the damn stealership for a 10 dollar filter.
