I don't do the math correctly but I usually fill up with about a gallon left in the tank and am usually running around 310 on the trip odometer, which seems around the 20mpg mark with a lean towards mostly freeway driving.

On a sidetracked note, I was goofing around with the new Magnum RT's real time average MPG display and decidied to reset it right in the middle of a cruise controlled 70 mph strecth outside of Dixon. Well the car was sitting around 24mph for 3 or 4 minutes when I got behind a couple of roadblockers doing 55 or so, for grins I moved over and floored it for about 5 seconds after which the average mpg from the previous 4 minutes dropped to 19, haha. I still love the V8's.

 

Thats the thing I dont know....i purchased the car of the auction and what i thought was a stock wrx that i can start from scratch to mess with turned out to be some old sport compact magazine car that has alraedy been messed with. THe guy messed with the electrical system and cast me major money to turn off my check engine and it has brembos and full one peice exhaust not including the downpipe. The car also has an up pipe and as far as i can tell a crank pulley. I have no idea what else the guy has done to the car but its definately killing me on gas. I bought a UTEC and hoping to create a MAP that can run a little lean....not lean enough to damage anything but a good kinda lean, make a stock setting and then one that tears people new ones and hands them their asses.

 

My mileage has really changed since I got the car. 16mpg in the winter in city driving. 23mpg in the winter on long trips. Now, I'm getting closer to 19-20mpg and 25-27mpg on trips.

I don't have a lead foot, I just live so close to work that the car barely has time to warm up. That mainly kills my mileage.

 

It is likely that the mods you have are causing the stock ECU to try and compensate by running ultra rich. Some dyno time and a custom tune for your mods (whether it be reflash or UTEC) will defintely help your mileage, as well as make the most power for your modifications.

 

Im definately taking the car to get tuned later on when I get some cash or when my utec comes in. Im just surprised that i have the same gas milage as an SUV, at first i thought it was normal because the car being four wheel drive and all. But yeah im defintely getting some tunning done.

 

OH by the way OAF thats some detailed data i like that i wish i was that organized. Mad Props man You can even see how much the gas went up over just a couple of months.....It seems like so long ago gas was only $2.... .

 

I remember when gas was ~$1.30, but thats nothing like what some of these old timers will remember.

 

do you still have the check engine light on?

 

no sir...but it cost me a good $400 to turn it off its a long story but if everyone wants to hear it ill tell it. I passed smog and all. Im getting the clutch put in and some mounts as well as the rest of the mods that were on the car right now as we speak or chat which ever......
