I realize that the 30mpg rating is under the most perfect circumstances. But i've seen so many people talk about the wonderful gas mileage and I just don't see it. . . .

If I drive like granny around town never getting the car over 2500rpms and taking it slow slow slow on takeoff I get slightly over 25mpg. If I drive like I want to drive I get 24mpg. My ride has right at 2000k on it and the best i've gotten thusfar is 31mpg on the Interstate.

. . . . I give up. I'm not at all impressed with the mileage but I love everything else about the car so much I guess i'll just have to live with it. From now on it's driving like I want to drive. To heck with that extra 1mpg.

I don't let any grass grow under my tires, and I have never gotten better than 27-27 1/2 mpg. Never did. I've even tried to get better.

I'm right there with you (albeit slightly lower). I've driven so delicately that it's almost a task getting from point A to point B because i've been so careful I didn't do anything that would use more gas.

The irony is that if I drive like a I want to drive the difference is so minimal.

My bride has a fit when she gets less than 34 mpg. 87 oct, Stock 5 speed.

How she does it is #1 Don't let me drive it 2 Keep it under 60 mph if all possible.
We live in the stix with lots of rolling hills. So You could say we're highway.

You need to keep the rpm's up. Lugging it with low revs uses more gas. Just smooth fluent shifts between 3000-4000 rpm's, and keep it under 60.

Try that for a tank and see what happens.

Only 2000K on the xB? This sounds about right. I too had the issue for the first 3K miles or so on my 2004 xB. Then my mileage went up after the first scheduled 5K mile oil change. Check your cold air tire pressure.

iKevin

Thanks for the hope Keitaro! I have serious doubts my box will pull off anything better but i'll keep faint hope.

RE: tire pressure . . . i'd gotten so **** about trying to get good MPG that I check it at least once a week. I even added a digital tire pressure gauge to my xmas wish list.

scion08

hey we have the same mileage. Im not too worried about it now, I was getting the same gas mileage when i had my tc so its np... if it gets better then thats cool too.

Frogger

I run premium in mine and I consistently get over 30-32 mpg in town.. I had another xB as a company car and my boss only liked to run 87 in it and it was getting 24 mpg every time i filled it up. I did a comparison with MY xB between 87 and 91 octane. I ran 2 tanks of each and got 24-25 mpg with 87 and 30-32 with 91.. I found it to be either the same cost as 87, or a bit cheaper to run premium in mine because of the mileage difference..

iKevin

Is it safe to run the higher octane in our engines? I remember reading somewhere that some of the Honda engines that are made for 87 octane would actually be harmed by 91.

draxcaliber

not just how you drive, but what kind of conditions your driving in. epa estimates don't take two very important factors into consideration
1. wind resistance (the xb is an aerodynamic brick after all)
2. alittle thing called terrain, so you drive up and down hills? or slow down to make turns? big factors.

somebody told me when they first got their xa, it got embarrising mpg, but then once the engine was broken in, it got great mpg. at 2000 miles, you haven't even changed your oil yet, so calm down.

...wait...2000k? is that 2000 miles, 2000 kilometers or 2000x1000=2,000,000 miles? that is alot of driving.

Octane will have no effect on mileage, nor harmful effects on your engine, just your wallet for no benefit.

Despite the brick appearance, the drag coefficient on the xB is very low. It has a lower rating than the Beetle, so you can't judge on looks alone.

I get a pretty solid 28MPG after almost 70,000 miles and I'm around the 80mph mark if traffic allows...

i dont know what i have done any different, i am getting 27 city and in between 35-42mpg highway. i always calculate my mileage when i refill. i havent done any engine mods other than the cold air intake. i will keep track of my mileage on my way back to north carolina and will try to post it up

mill0048

I was getting 28/29 mpg in all city diriving in my stock 5 speed xB with no extra passengers or load and with tires at 42psi.

Even now with the supercharger I get 27/28 mpg. Virtually same scenario as above (except engine mods and now with 91 octane).

I've got 20k on the odo. I never hesitate to get down on it when I want and typically come close to redlining a few times a week. I rarely exceed 60mph. I'm an enthusiatsic driver to say the least...

There are so many variable involved with getting good gas mileage: load/cargo capacity, aftermarket wheels, replacement tires, general maintenance (oil quality, air filter , tire pressure & so on), driving habits, weather, engine modifications, speed. It's hard to say where you might be going wrong if it's even your fault at all.

But as someone else said, try variating your RPMs a bit to find the sweet spot for different traffic scenarios. I typically operate in the 3k - 5k range when accelerating and go to 5th gear when maintaining speed above 35mph (around 2k rpms). Bogging the engine on heavy loads (accelerating or carrying extra weight) will not help at all. Perhaps you could drive the way you WANT for a tank and see how that works. Anyway, I hope you can find a few extra mpg!

i've noticed my xb has dropped in gas mileage a lot this past tankful. looks like the winter additives are in there cuz my mileage dropped big time.

dugzilla

I have almost 60k and get about 30mpg no matter how I drive it. When I go on long trips it's usually 32 or so.

sandwich

13k miles here and i've been getting 30+ since day one. i averages almost 35 during break-in.

i normally shift around 3000-3500..and on the highway i cruise at 75-80.. i'm still averaging city/highway combined at 30mpg.

ROBs-xB

its not safe to run anything higher than 87 octane on an Xb
without a Chip modification for the higher octane. I asked the dealer
about that when i got mine and they said if you put anything higher
than 87 it could mess up your timeing or cause other damages because
the cars are programed to run on 87 octane.

YourNameHere

^^^ no it doesnt.

i normaly run midgrade and get 29mpg mixed. highway i get about 34mpg. if you figure out how much more your spending on 25mpg and 30mpg its really not much. if you enjoy driving the car hard...drive it hard.

hwybox

i've got 2200 mi on my xb, and get between 31-37 mpg on 89%E10 ethonal, with a mix of city/hwy. and i asked the dealer if it was ok to run 10%ethonal(E10) and he showed me in the owners manuel its recomended.

teabox

Man, I guess you east coast guys are having problems with mpg. yesturday, I got 321.4 miles on one tank, and I still had enough for maybe 10 more miles, and filled it up. I made 321.4 miles on one tank by driving it a bit granny style and a bit racey style(2-3K). I even floored it twice, all the way to redline and I still got 321.4miles, with 30mph traffic.

I guess when your scion is new, it wastes more gas due to break-in. Once u hit 15K or so, mpg increase to the point where u make miracles like me.
