I have a '94 accord 4-door with 145000 miles. The car runs
absolutely great, but recently the mileage has gone down
10-15% (from 28 city to 24, 33 highway to 29). I've verified
this over several tankfuls. There's no noticeable difference
in performance, acceleration, engine smoothness, etc. Nothing
appears to have changed except the mileage.

Anyone have any suggestions on what to look for?

TIA

In my case the car was running too rich. The problem was the O2 sensor.
Although I think that my mileage at the time was worse than the
difference you are reporting.

Don't forget brakes. A stuck caliper or bad power brakes booster will
make the brakes stick on and cause the same symptoms. Sometimes you
can feel a loss of power but the mileage drop will also be noticeable.

You might be able to smell a stuck brake system (burnt asbestos -
kinda like a slipping clutch).
