I've got about 6,000 miles on my odometer (put on since May), and I'm consistently getting about 23 mpg. I'm driving SO gently, rarely get the RPM's above 3,000, and I've tried hard to slow-start at stops. Most of my driving is in the city (maybe 50 miles a tank on the interstate). The only time I've gotten better was on a long road trip---and that was 30mpg. The dealer supposedly reset my computer, but I didn't see any difference. I do have the oem intake. Any ideas? My mom's 20 year old LeSabre gets better mileage that this.

 

lol, welcome to the club .... we get 25 on avg....

 

What transmission and wheels do you have?

 

That is so odd, but I also think weather and elevation has something to do with it.

I had a 5 speed xB with 16" wheels, Blitz exhaust and Injen intake and I averaged about 32 mpg city/highway (mixed driving). I always shifted around 3500-4000 rpm too. I don't know why there is so much variation between what people say they get.

The funny thing is that my turbo Miata is consistently getting 26 mpg.

 

if u drive below 3000 rpm something is very very wrong.

 

I check my mileage every time I get gas. I also have the short ram intake and axleback exhaust.

It is consistantly 30-31 mpg. If you are getting 22 I would think something is wrong.

I would have the dealer figure it out,

good luck

 

i for the most part am NEVER driving BELOW 3000 and i get 25-32 mpg.

 

All factory Automatic here and I avg 33-34

 

I also have an all factory auto, and i only get like 20-22mpg, i have 18" wheels though. ive sent it to the dealer twice now and they cant figure out the milage thing.. i dunno..

 

I was having a similar problem. My car was getting really bad mileage (about 220 on a full tank) luckly the check engine, vsc, trac light came on. They traced it to a bad MAF. Also I have the Auto with 6000 miles on it

 

ive never had a problem...got 23k on my box and always get 28+...

 

i agreee mines is the same im lucky if i get 220miles on a full tank

 

I'm no expert but I've heard that accelerating extremely slow isn't always the most effiecient either. I havent had my box to too long but I've been through several tanks and so far I've gotten 32 all in city and once on mixed hwy/city I got 35. I tend to accelerate fast enough to keep up with traffic and try to get through the gears quickly and cruise in 4th and 5th gear as much as possible. Obviously I have a 5 speed, I'm bone stock so far with stock wheels. Most of time while in traffic under 50mph I'm close to or below 3000 rpm but I get there quick.

 

people must drive slow around you. if i'm shifting anywhere near as low as 3k i'm getting left in the dust of grandma's and the like.

 

How did you calculate your gas mileage? Did you divide the mileage on the trip computer by 11.9 gallons (xB's tank size)?

I drive over 3KRPMs highway, jack rabbit starts at the light and still get 32-34MPG (no A/C).

 

i got auto stock, city/mix 32 atleast, with 35 being best (all highway)
i'd def. let the dealer take a look at mine if i got below 25 mpg! 22 is ridiculous!

 

Hope not, unless he has his box towed into the gas station with an empty tank every time he fills up.

You use the *actual amount* it takes to refill, not 11.9, to make the calculation.

i have 2000 miles on my xb and i always get around 35 mpg. I have 18 inch wheels and dropped with df210. Better contact the dealer or something. Might as well get a v8 if your gonna get 25mpg

 

im getting around the 220 mark when the fuel light comes on. . ive averaged it out to be like 21-21 mpg with the 5 speed. i also did 2 tests driving like a bat outta hell and driving like an old lady and the results are only off by like 30 miles a tank. also i change my wheels left and right and havent noticed a difference. the only thing big wheels gets me is new brakes every 15k miles, wich my dealership said is normal

 

My average mileage is around 33 mpg, my best is 37 mpg and worse is 31 mpg. I'm also rollin on stockies and I have a manual tranny.
