I usually can get around 320 - 350 miles per tank.
18 gallon tank in mixed driving conditions.

I'm definitely on the low end, despite a brand new EGR, and a tune up about 8K miles ago. Average around 230miles per tank, or 13 mpg. Highway is better, but not by much. How some are getting around 30 is beyond me. Anyhow i'll probably sell my car and get a newer one soon.

B..are you going off actual gas mileage by dividing mileage by gallons per the pump?

if so when was the last time your O2 sensor was replaced. That is usually the culprit of gas mileage. Although you have an SSEi like I do... and superchargers have a correlation between my foot and the floor (darn pedal keeps getting trapped down there)

An easy way to keep track of your mileage is to sign up with your local version of www.gasbuddy.com

They have a fuel logbook there and will compute mileage for you. No math. All you gotta do is write your odometer reading on your receipt, plug in the info to the site, and read (okay, that last step might be hard for some of us)

My mileage sucks right now, even with the new O2 sensor. Cold wether + Freeze Baby + Remote starter = Bad MPG

I can get close to EPA estimates in warm weather or all highway driving.
You will not get good mileage around town in the cold northern climates.
Its the nature of the beast..

As well consider different blends of fuel for different states. That has a big deciding factor on mileage and power.

I compute gas mileage everytime i fill up the tank, which i usually only do once the warning light goes off. It'* the only thing i use the trip odometer for actually. The "math" is just simple division!

Anyhow, i know when i got my car it was getting around 22mpg or so, and last night it was 15mpg. I've always used premium (as recommended by all you SSEi folks), but as some of you mentioned, i don't know if the O2 sensor has ever been changed. It hasn't since i got the car at 60K miles, now it is at 105K. I actually really like my Bonnie, and wouldn't want to sell it....but instead of "nickel and diming" me, i spend around $2K a year getting the dang thing fixed.

For those who HAVE changed the O2 sensor themselves: do i need any special tools, is the procedure very hard? Anyone have a part number for a 1994 SSEi? Thanks!

I meant the part number for the O2 sensor, not the entire car. thanks.

Nice comment for a faimily content site. Please change it.

Procedure is simple. The sensor is located on your rear exhaust manifold and can be done easliy from the passenger side of the car. Some use a large wrench, others use an O2 socket (has a slit in it for the wire), I used a crow foot.

Unhook electrical connector and unscrew sensor. Install new one and reconnect. Some find it helpful to remove the strut bar, I didn't need to.
