Better Gas Mileage?

Better Gas Mileage?
I was doing a little research around here, and would like to know what I can do to get better gas mileage on my 91. I get roughly 200 on galons which is crazy.
All i have done is an intake, and a recent tune up was done.
Exhaust or 02 sensor will help?
Thanks

Cannot believe gas makes much difference. If octane level low, knock sensor detects knocking, retards timing, consumption jumps.
Many gas stations have rigged pump measure/ctrl -chips: you get robbed if they give 15% less than measured/paid.

Check your tire pressure
Replace your o2 sensor
possible that your cat is clogged or partially clogged, but not likely
If you stop-and-go a lot, poor gas mileage is almost a given. These cars are fairly heavy and have 6 cylinders. The only way to get over 25 mpg is on the freeway.
I seemed to get better mpg when I put in the fidanza and synthetic gear oil in the tranny. I don't know which (or both) made the difference, but I can now get a legitimate 30 mpg on the highway. The mpg is still good with my JDM engine, although I have only made one all highway trip and I got 28 mpg.
Around town, it sucks because I let the car warm up for several minutes in the morning and I only drive two miles to work.

All run by computer or something like that he said. I still don't know WTF happened till this day.
"Its not possible" - maybe, maybe not. There are some not so nice fillin stations... Your nonfilling might also be a electro/mech malfunction, not salesperson fault. But happily a very nice 'glicth' for the shop owner...
But yes, how can one prove? I think there are lots of innocent men in jail because of our 'foolproof' electronic society... even waiting in the electric chair -line. And this is justice?
Next time u buy only with 10$, I guess?
Organized crime is in the 'trimmed fuel gauge chip' -business, according media reports. The fuel filling stations are inspected with some std certain calibration intervals, amount at 5? or 10 gallon or whatever. The cips have been trimmed so that at that exact amount they are accurate. But on any other amount u get 1-15% less. Nice, eh? The salesboy does not know about this, its the whole chain or owner that does this systematically. Theres no way u can be certain, unless u use your own canisters which have known capacity.

im almost positive your bad gas mileage is due to your bad knock sensor, ive been having the exact same problem. look in the how to's to see how it is done. the symptoms are loss of power under 3000 rpms, and low gas mileage. My car is drinking gas right now and im just waiting for the sensor.
