i bought my 06 xb brand new in march of 07 after i came back from a 15 month tour in iraq and in recent months i have noticed that my gas mileage has dropped significantly. lastnight i hooked an Actron Auto Scanner Plus CP 9180 up to my xb's computer and it said that all my codes were just fine. i need to know wut could be the problem. any suggestions?

 

find your actual mileage..
could be winter gas as well



also..I'd like to say thank you
for serving our country

 

wut do you mean by find my accual mileage? and ive never heard of winter gas, wut is the difference




your welcome. ill never serve again tho it messed me up too much

 

find out what your actual mileage is..
fill up your tank note your mileage

drive till you need to fill up again..write down your mileage
note how many miles you have driven
and divide by how many gallons of gas you used

you will then be able to say..my box gets 30 mpg's or 23 mpgs.. or whatever it is mpg's you are getting

otherwise..when you say you are getting bad MPG's it leaves a lot to the imagination

how bad is your mileage?

 

Yea, I don't trust the scanners. My scangauge has never been very accurate in averaging the mileage.

What you need to do is divide the miles you got out of the tank by the number of gallons it took to fill up. Like Mike said.

Winter gas is a different blend of fuel that is better in cold weather. Unfortunately, it's not as good when it comes to mileage. Winter gas generally gets pushed out sometime in October.

I went from 31mpg on regular stuff to 26mpg on winter stuff.

 

ditto for me on the winter gas...my mileage has dropped the last 3-4 tankfuls.

 

Winter gas plus the 10% ethanol blend in Indiana really sucks...

 

i asked around at the local gas stations down here today and found that no one uses winter gas ever around here it just doesnt get cold enough. and half the gas stations dont even offer ethenol. gas is also cheap! $1.82 per gallon and in oklahoma city its as low as $ 1.77 per gallon! so i guess it makes up for my bad mileage! not really could it be that my fuel system is f***ed?

 

Lawton(Yuck) you must be in the Army. Have to be. i was stationed in Altus [C-17](double yuck yuck). Even though you are part of the gfamily I still want to thank you for your dedication and sacrafice. Much luv bro.

I dont know what the problem is, I have noticed a problem with mine. It use to eat gas like an 8 cyln car but found out what was killing me were the bosch platnium spark plugs. so I went and got me plugs from toyota. I doesnt eat it much anymore but still i am getting less. I filled up fri night and now 214 miles with 1/4 tank to go doesnt seem like much to me. I use to get 280 but i will see if it will be the same next tank. I am really tired of the small tank. I am still wondering would I buy a second generation xB. I really want something that can give me 350 city and maybe 4 to 600 miles hwy. Good luck with that and if you should find as piece to that puzzle, let me know.

 

alright, first off, you gotta actually take the time to calculate your MPG, so far all we have is you saying it is terrible, but we have no idea how terrible.

also, is it an automatic or manual?

how many miles are on your box? when is the last time you changed the oil, air filter, spark plugs, are your tires properly inflated? how does your car drive? does it seem sluggish or have engine hesitation?

if you box is an 06, and you bought it in 07, you should still have plenty of warranty left, take it to your dealership and ask for a consumption test.

and lastly, if gas in your area is under 2 dollars a gallon, STFU! since gas for my supercharged tc is still about 2.50 a gallon. lol, jk.

 

i just filled my tank today to findout my exact mileage so i will let you all know how bad it is when i need to fill it up again. its manual i have 27000 miles on it and it drives great and just changed the oil, just put a k&n shortram intake on it 3 weeks ago, and have bosch plat 4+ spark plugs on hand but haven't installed them yet

 

For me i have an 04 I bought Jan 2nd 2004 i now have 64k miles it is auto last time all those things were changed was at 50k. I just changed back to toy plugs cause now I found out that bosh not goo fo that car. IO am at 214 mile with a 1/4 more to go. before i use to get 280 a tank with the light on. now it is less. mine moves and not sluggish, I even had throttle bod sprayed out, usde lucas injector cleaner and i still think it is bad.

 

what is everyone averaging for mileage?

Right now I only seem to get 250 miles per tank.

 

First off Vanilla is a 2005 auto box, slightly oversize tires (which makes the odo 6.1% off, meaning I need to multiply the odo reading by 1.06 to get true mileage when figuring MPG).

Long trip, summer gas, highway driving: between 36-39MPG.

City driving (the majority for Vanilla), summer gas: 27-30MPG.

If I'm driving like a squirrel (it happens on occasion) I can drop all the way to 22MPG...

(All of this is on "Top Tier" - usually Chevron - fuel and synthetic oil.)

 

BTW, good looking box, Garrett, and a rare one in your neck of the woods. :D

 

Pffft, regular here is down to $2.739/gal. The Seneca reservation 15 miles away is charging ~$2.25 or so (and they're tax-free, so they're really fleecing people since the wholesale price is currently $1.25/gal).

 

? paul... do the grill blockers help with fuel mileage? where did you get the blue dash lights? and i have grage stored my car in the winters and now this year i dont have a grage and need to know how the xb handles in the snow since its supposed to be a bad winter down here this year. i am origanlly from waunakee wisconsin so i know how to drive in snow but i havent had the chance to take mine out for the icy back road test

 

The box actually handles surprisingly well in up to about 5 inches of snow with decent tires.

Over 5 inches and you are taking chances with the front, and especially rear, lips...

(There are times I wish I had access to the original bB lips in winter...)

 

Blocking the bottom grille seemed to help. I have my tire pressure pretty high, accelerate gently, and actually stick to the speed limit (no matter how many arguments it starts with my better half). On summer gas, I was averaging 37-38mpg, now, I'm down to 34-35. This weekend, I'm going to block off most of the mid grille too, now that it takes noticeably longer for the engine to warm up with the change in weather.

The blue HVAC lights were from Oznium (along with the flexible 16-LED dome light), and my gauge cluster has piece of light gels from a free Lee Filters swatch book between the LEDs and the clear plastic piece on the gauge face.

As far as driving the xB in the winter, it's not bad. It's not powerful enough to get you in much trouble, even with all-season tires. I should invest in snow tires, admittedly, but I am cheap. FWD + traction control = competent in the snow. Not amazing, but it won't freak you out too badly.

 

I just did 2 - 4 hour trips in the xb and averaged 35.7 mpg modded with 98,000 miles....
