gas mileage

My first fill up
it took 7 gals I guess the guage is not calibrated correctly, is that fixable?
Anyhow I went 250 miles on that 7 gallons is that about right for this car?
1/2 freeway at 70 mph and 1/2 city driving stop and go.
1996 1.3 5 speed power steering and booster brakes.

looks like 35 mpg , can this car get more?

I get something like 10 liters by 100km in the city and that's considering my tank is leaking a lot (converted it's only 23.5mpg... I gess I must change some stuff in my car hey?) and 5.8 on the highway (40mpg) and that's on a 3 banger... HELP!!! what can I change for my mpg to get better? I already have my timing belt, my whole exhaust system and my brakes so mpg will come later any way =P Also, when I changed my spark plugs, they were all black, what could it be?

"looks like 35 mpg , can this car get more?"

I know someone on the www.teamswift.net forum said that by changing his cams for the ones superfl1 makes he got 5 more mpg and a lot of power added at the same time but I'm not shure he makes cams for 1.3L...

Oh yeah, also, when the gauge reach the red line, you still have about 10 liters inside the tank so it's normal you coul only fill it with 7 gallons

My '96 1.0 3-cyl (145k) gets only a little better: 37-39 MPG mixed city/highway. The MPG does not really seem to improve when I baby it (light right foot, shift by ~3,000 RPM).

When I fill up, my fuel guage is fairly close to Empty with about 250 miles on the trip ODO, yet only about 6 or 6.5 gallons fit in the (10 gal) tank.
