ok on a full tank of 90 octane i get 235 on a whole tank, on 92 octance i get 237. each are averaged out of two tanks. i only boost when merging wiht traffic i use it twice a day but nothing pedal happy. its about 50/50 freeway/city driving. i dunno what you other 94 ssei'* are getting but, this has to be low, right? what should i do to try and get the mileage better?

That seems about right for a 10 year old car. I wouldnt worry at all.

New o2 is the big one, plugs wires, PCV, properly inflated tires, clean injectors, all uneccessary junk outta the car. I know you have a new air filter, etc.

If you really wanna dig, synthetic oil will, new tranny fluid, lighter rims etc.

that works out to being 13 MPG. Definately too low. You should be at more around 25 MPG on the highway average.

Ahhh, its good that someone did the math here! Thats way too low then. What size our are tanks?

18 gal

im lucky to see 275 out of my tank....225 usually

jeeze. how are you guys driving? You must hotrod it or something. lol. I usually get over 400 miles in my 97. (or high 300'* if it were a bonne because my gas tank is 20 gallons instead of 18.)

Trips to KC were 100 miles, get a little under 3/4 a tank one way, soo yea, med-high 300'* easy on cruise

hot rodding...225

pure highway...275

I think that i have made a revealtion. I have driven my car all the way to empty and filled it up, driven the car to half a tank and filled it up. I get better gas milage when i only go to half a tank

In all city i get 16 MPG I cant remember the miles, but when i was driving 80+ miles to work and back I was getting 200+miles on a half or tank, of regular, nothin fancy
