Yeah, my mileage is way down. I figured that it was either the gas or my computer being slow to adjust (does that happen?)

I don't know how the computer would be slow to adjust...??

Also when checking your gas mileage- figure it out mathematically as well as seeing what the DIC says. My computer reads high by apprx 1mpg. When it says 25.6mpg, and then I do the math - it will really be 24.6.

Well my battery died a couple days ago so I got a boost from a friend and when it was boosted, the whole car reset itself.
So I figured I'll try and take it easy and let the gas mileage adjust to a new foot
It'* sort of going up and down in between 16.3 and 17.5 now.

Wow that'* alot, that'* like a Yaris

Haha what'* the Firebird getting for mileage?

its about 1/4 mpg to 1/2 mpg

Shadowfax is fine. That milage is only a little on the low side. Probable suffered from longer warm ups because of winter cold and your driving habits that week. Whenever someone asks about milage you get a wide array of different MPGs. Why? Cause everybodys different, Heavy foot, light foot,some mods,no mods,some city, no city,etc. And most of all ,were now paying much closer attention to our milage because the price is so high. I could quote you my milage for the heck of it but thats my habits and such.I will tell you how to save on gas right now. Ease your foot on the gas, time the traffic lights,don't race up to them and away. And most of all drive under the limit especiall on the X-way. There is a minimum limit on all x-ways stay slightly above in the right lane and SLOW DOWN in general. It works! You get home like 3 minuts later than usual on like a 25 mile trip and you saved yourself moore than you would believe.
