lol... 06 automatic coupe, before the blower, I used to get around 240-270 or so, before the light comes on. After the blower (a recent addition), the best I got was 16.7 mpg. (On a tank where I didn't go WOT that much) Whenever I hear about people getting 25-30 mpg, makes me think I got some kind of lemon from infiniti or that they got a super mileage package that I was unaware of when purchasing

 

Will do, it will be a few weeks till I'll be able to do it. I'll keep y'all posted.

 

Shell premium. All I put in. Get better mpg with shell over speedway. Anyway to kinda test the oxygen sensor before changing it. Off hand does anyone know how much the cost and how difficult to diy?

 

I average 325.4 miles a tank (19.35 mpg) and that's with about 60/40 hwy/cty including a little spirited driving here and there. Best I've ever done is 403.1 (23.5 mpg) on a tank that was mostly highway...but I probably average 90mph on the highway so I could do a bit better I'm sure. It surprises me that so many people don't even come close to 300 miles on a tank. I mean, I don't drive very gently at all and I think I get decent gas mileage. I guess it could be the altitude and other factors as well. I live in Albuquerque, so we are very high altitude. I usually fill up well after the light has come on which happens past 300 miles.

I track all of my gas mileage and expenses with an Android app that I built called DriverDiary. I've always been into tracking my fuel economy and expenses so I had to ditch the spreadsheet and build me an app. It kind of opens your eyes to how much it truly costs you to own and drive a vehicle. Check it out and see if you like it, there is a free version. I also attached a couple screen shots so you can see my averages/highs/lows.

^^ that's awesome! I wish you build one for iPhones too

 

Thanks! An iPhone and Windows Mobile version is in the works.

 

That's so cool please let me know when it's done.

 

i get about 300 miles, daily driven, city and freeway.

 

I just purchased my 2005 Coupe just over a week ago and have put one full tank through it so far. 80% of the driving was highway driving around 125km/h (78 mph) and I managed to get around 560kms out of it, which is around 347 miles. Used 94 octane.

The upgrades I have are the Stillen intake with z-tube and upgraded plenum spacer.

250 ish. mixed freeway/city. racecar driver/gma

 

I just filled up 18.5 gallons with a mileage of 446.... San Fransisco to Orange County! That's the most I have ever done

 

Oh nice! I live in Orange County myself and love the drive to San Francisco. Good to know our rides can make the drive on one tank

 

I go through around a tank a week (brutal but worth it), and I average 330 miles on a tank with my 08 sedan.

 

I get around 200-250 miles on tank driving around town.

 

^damn thats kinda bad...i think the max i've ever gotten out of a tank was like 475 and that was on a roadtrip but i can usually get 350-375 on normal driving....less now that i'm lowered more though :/
