Plugs, wires have been changed. Will the O2 sensor make a difference? Or is the mpg about right for this model?.. Thanks..
Using premium in an engine with a PCM that can't really adjust for it, like ours, can/will reduce mileage. Age can increase the octane need through hot spots that develop from carbon or sharp edges that form... but I say you give regular a chance. Do a few tankfulls at least.

I agree with this comment, and so do others, including professional race car drivers - using high octane gas in a normally aspirated engine designed for regular unleaded gas is a waste of money.

I have pulled 30+ no matter what fuel I use in my 95... I pulled a 33 coming through WV and had ran 93 oct for 1100 miles...
But yes its true there is less burnable fuel with 93.. I run 87 99.99% of the time in all of my cars... And both the 91 LE and 95 SE will pull better than 30 mpg on the road

I get up to about 26MPG, mixed now that it'* warm. But, I just changed my O2 recently, switched to full synth oil, and did a tune up. Also, I almost never use the AC. I prefer the feel of the windows down and the music up.

23-25 city is exceptional. The states that require the10% ethanol blended fuels, like ours caused people to get 2-3 mpg less. My friend regularly gets 27mpg in his intrepid. He took a trip to PA, filled up there and got 31 on the way home. Just shows you what different fuel blends can do to mileage.
Can't get close to 18 around town with ethanol.
