Default gas mileage

hi guys. i just purchased my first bonnie EVER this morning and it is looking real sharp. ive read on fueleconomy.gov that a 97 bonnie gets about 22 mpg, but other places ive heard around 28. what do you guys as the actual owners get for gas mileage?

Mine'* been 20 or a little better since the day I bought it new. some here say different; I think they're lying.

I have gotten a little better mileage lately, though, but it'* just because California has switched over to (real) gasoline from the "reformulated" crapola for the winter.

I just returned home from a 1800 mile trip to MN. We averaged 26 MPG, but we were running at a pretty strong clip (80-88 MPH) the whole way. That was three people and tons of luggage. I have 135,000 on it.

Short local trips around town - 20-22 MPG.

73 mph interstate driving with full load of luggage - 29 MPG
(this was a 340 mile non-stop run with very light traffic, 45 degrees, dry roads)

I usually get from 22-26 with mixed driving conditions.

I average right at 20 MPG, including rush hour to and from work in my 98 SE.

If you want to keep track, sign up at your local version of www.gasbuddy.com

You can keep a Fuel Logbook that will calculate your MPGs for you, as well as some other stuff.
