It could be, and that'* not necessarily bad mpg'*, it depends on several factors. Are those mpg'* all highway, combined, or city? How recent since last tune-up?

How long since the O2 sensor was changed? Do you even know? What about the other tuneup items like plugs, wires, PCV, fuel filter, air filter, etc? Along with all the driving habits, etc.

The best I've logged in my pretty well modified 93 is 32 mpg at 70mph on the freeway. I can still beat 30 at 75mph on long trips to CA (which I do a couple times a year).

well SSEis are not exactly hybrids....they do consume gas. Are you a bit hard on the pedal? 20 sounds about right to me. But it probably needs a tune up like willwrne said.

A tune up is VERY easy to do. Like willwren said, I would also suggest a o2 sensor, you can pick one of those up at any parts store, installing them is just a few turns of a wrench and a few wires. As for plugs, while you are at that store getting the 02 sensor, grab 6 NGK TR55 spark plugs, they are usually only a buck and a half a piece, installing them is also only a few turns of a spark plug socket (if you dont have one of those, you will need one, or just borrow one from a friend). How many miles are on this car? The spark wires may need replacing also.

Next thing would be to check the air filter to se if it is dirty, this can really cut down on mileage. I would reccomend replacing it with a K&N drop in, but if you don't have the bux, then something comparible will work.

Also, you may want to replace your PCV valve.

Shopping List:
(6) NGK TR55 Spark Plugs
(1) Set of spark wires
(1) Air filter
(1) PCV Valve
(1) Oxygen Sensor

we are here to guide you in the installation if needed!

Good luck!

EDIT: sorry Bill, you basically said all this, i did not read your whole post

When you buy and O2 sensor, buy AC Delco only. GMPartsDirect.com has very good prices. Many here have found Bosch to malfunction and go bad in less than a month.
