ok, so the window stick on a brand new XB said 22/29 or was it 22/28 for my 2010 XB. I am not getting anywhere near it. I heard that some get 30-33 mpg, wtf???

I commute 50/50 local and highways about 8-10 miles to work and then about 7 miles from work to school and its also 50/50 local and highway. By the time I fill up my tank by gas mileage is about 21-22 mpg. I have a semi heavy foot on the gas peddle but I rarely red line.

ok so, for a while now I was thinking that I have a heavy foot thats why my mpg is bad but until I took the car on a road trip to vegas and frisco and got only 25mpg avg. On the way to frisco was better at 26 mpg. I know it was not heavy foot because I had it on cruise control at 74-77 mph. I also tested without cruise control and got about the same mpg around 24-25 mpg.

So what is wrong with my gas mileage? How can I improve my mpg?

I really love this car but I really want to sell it because of the gas mileage. I rather drive an V6 with mpg like what I am getting. My previous car was a 350z and I used to get 20mpg, I rather drive that since the mpg isn't much difference.

 

75 mph isn't going to get you good gas mileage. those ratings are based off 60-65 mph. try that.

 

20-25 in town around 40mph stop and go. 28-30 on highway around 65-70mph

 

[QUOTE=criminaltc;3882099]75 mph isn't going to get you good gas mileage. those ratings are based off 60-65 mph. try that.[/QU! Who's gonna drive 65mph on a 400 mile trip? Gonna take me forever to get there. I'm going to Vegas soon, so ill try 65 to 70mph and see what I get.

 

I get roughly 325 miles to my tank...I fill up weekly as I commute 32 miles each way to work which totally about 320 a week....all highway driving and I cruise it at about 67mph everyday... I range about 25-28 mpg nothing more that I can tell....also one thing to consider about your commute is not only speed but the weight you are lugging around in your car I take it your making a 400 mile trip you gonna have luggage passengers etc etc...yeah all that factors to the mpg...just things to keep in mind...

 

I did a 2000 mile trip from Phoenix AZ to Wisconsin and I got 29-30MPG and the whole time doing i was doing about 73MPH and it was weighed down with luggage. But that's a 2010 tC.

 

My last two fills were both 27.8 MPG hand calculated (over 300mi each) with college town summer driving and no highway, but a fair amount of lights and rush hour(s) traffic. I generally drive for MPG.

 

I've gotten 300mi-330mi to a tank with 50/50 Highway/City Traffic.

Which is good enough for me - Tank costs $50 (CAD) to fill SMH

 

turbo 300whp getting 24mpg
50/50 driving but still having fun hitting boost

 

OUCH! its around $35.00 for me to fill.

 

Wow, you are lucky.

 

26-27mpg overall in my 2010 5-speed. Mostly city stop and go...some freeway. Los Angeles area. I like to shift at about 3k rpm...no higher than 3500. On a recent drive to Vegas I got 32mpg doin 75. Oh and I run Toyota 0W20 oil if it means anything.

 

I wonder why im not seeing as good as you guys. I dont go over 3k for shifting unless freeway cruising.

 

I usually get around 25.5-26.5 MPG. Last time I took a road trip, I managed to get it up to 30 MPG (the trip computer read around 32-33.5 MPG but I calculated it by hand and got 30 MPG) but I was in no hurry and was crusing around 69, I specifically set the cruise control to 69 because it entertains me the whole way. As for oil, I run Mobil 0W20.

 

It's also going to depend on your tires & wheels. When I got rid of the 16" steelies & OEM tires my mileage dropped by about 10%, and I drive about 90% freeway. In pure city driving my mpg drops by more than 20% compared to before the + size tires & wheels. I'm guessing your TRD 19's have something to do with it.

 

On a recent 300-ish mile round trip I made, I got about 28 mpg's.

Although usually I do get around 25-26 mpgs driving mainly streets with a little bit of freeway included.

 

i didnt even think about that because right when i put them back on i noticed. Makes a lot of sense. Especially since i was at a lower RPM driving in town and through the gears on the steelies. Didnt even click until now.

 

Canadian dollars have a lower exchange rate than US dollars.
Well, last summer I was getting about 2 MPG better than this summer. My interpretation is my last year's performance mods are taking their toll. Unutilized performance mods shouldn't cost you, but I know darned fine I'm using mine regularly, even though it's not by intention!

 

In the summer I have 27-27.5 MPG calculated by hand, see 29.5-30 on the readout in the dash. Then again, I have an 8 mile 55-60 mph drive to work with a couple stoplights. How you accelerate and how often you use cruise control makes a big difference as well.

 

Yeah i cant really judge MPG my commute consists of three lights and nothing over 45mph
