95 Accord 2.2 non vtec poor fuel economy
Hello I just bought a 95 Accord 2.2 non vtec with 59k Miles was parked for 14 years. Replaced plugs wires distributor cap and rotor (all oem), replaces starter, alternator, battery, oil and filter, air fuel ratio sensor on manifold, intermediate exhaust pipe. Cats are not clogged. I have run cheap fuel and 93 fuel, I am only getting 18mpg highway at 65mph and rpms are at 2600-2800. I’ve changed the air filter. I’m good with diesel pickups but new to Honda’s. Anything I am missing?

~2700 @70MPH
~3100 @80MPH
If this is correct you have the factory transmission.
Does the car drive normally? Any hesitation or lack of power? Does it smoothly get up to speed or does it seem like you have to push the car to get it to move?
What brand O2 sensor did you use? Bosch and Bosch-type sensors are crap and lazy, if they look like a beer can...
They are going to be lazy and inaccurate.
Purchase and use Denso, Delco, NTK type O2 sensors.
Verify your MAP/TPS/IAT sensors are all working within normal parameters.
Verify there is no backpressure from clogged muffler or mid pipe, it may not rattle but a critter may have partially blocked your muffler with bedding material.
Verify there is no clog inside the air intake muffler/resonator before the air filter.
Verify your battery is holding a proper charge. Should be 12.4V with everything off. Engine running should be 14.4V
Verify your tires are correctly filled, check tire pressures when the tires are cold. Ideally first thing in the morning before any sun has warmed them up.
Door jamb sticker is recommended pressure for comfort(NVH). Increase pressure to reduce rolling resistance and increase mileage. Check tire sidewall for maximum allowed pressure.
Verify your tires are wearing evenly. If the front tires are scalloping every other inner tread block, your wheel bearings are probably in need of replacement. Look for any unusually/uneven wearing.
Verify undercarriage splash shield is in place and fender liners are in place.
Verify the PS pump or A/C clutch are not dragging or require excessive effort to turn.
Verify your base timing is set correctly, warm up the engine, turn it off, jumper two wire blue connector from under the glovebox and verify timing is within the three notches on the harmonic damper/crank pulley.
Verify your brakes are not dragging. A car that has sat with the parking brake on may not be fully releasing the rear wheel(s). Or the caliper sliders may be sticking, remove calipers and pads from rotors, check for any sticking pads, clean and relube all sliding surfaces(pad ends, caliper sliders)
Verify there are no body panels that are loose or ill fitting, verify there are no added un-needed wings/spoilers/airdams that are pure ricer-ness causing drag.
Drive smoothly, no abrupt acceleration/deceleration.
FWIW, '95 EX coupe with wrong transmission gets 29MPG, and I don't drive all that civilized all the time.
