Fuel economy: help settle a debate

My wife and I are in the middle of an argument on what is making our 03 ZX3 get poor gas mileage.
My take on this is that it needs wheel bearings, tranny filter and fluid change, exhaust fixed, and new o2 sensors.
My wife thinks it doesn't need any of that and that if there are no check engine lights on it doesn't matter.
Granted that car runs great with no performance issues or check engine lights but couldn't these things make it get bad gas mileage?
Both of us drive like old grannys so that's not a factor and niether is the basic tune up stuff either. It is an auto tranny.

I'd add to that= plugs, wires, fuel filter. How many miles are on your foci? o2 senser & fixing the exhaust would help.

Kind of pointless unless we know what kind of average MPG you're getting ...

Oh and it doesn't leak, burn, or use any oil.

I previously had a 2001 zx3 auto, it typically averaged 25 mpg with 90,000 miles. No matter how I drove that car, the mileage always was disappointing for such a small car. I never got below 19mpg in town, but it was tough to achieve over 26 mpg.

you can tell when wheel bearings go bad, do they feel like they have excess drag? could also be a dragging caliper or stuck shoe.

Did this occur over night or was it slowly getting bad?

Well the. Wheel bearings in the rear of the car seemed sloppy to me when I checked the brakes so I figured the front ones would be the same too. But that's when I had the drum off that they felt sloppy. When I put the spindle nut back on it seems tight.
Its been this way since we got it over a year ago. But only been monitoring it for the past 2 months.

You should point out to wife that not having a check engine light means nothing now. I've seen cars run so bad that they would not stay running at all and like that for a good long while, no light ever posted. On multiple cars. Ford has damped the light response, light often does not come on at all until way later if at all. Does not mean at all car has nothing wrong with it. They started doing that around 2000 or so. It lowers warranty claims.

The light is in no way linear with something bad happening now.
