I just got my xB about a week and a half ago and my first two fill ups yielded a 21 mpg average!! What gives? I bought the vehicle to save gas as my V8 Tundra was killing me. Don't get me wrong, this is still double my Tundra's mpg, but nowhere near the 28-30 I expected, nevermind the claimed 33/37. I do alot of LA traffic driving, but always shift around 3k rpm and cruise at ~70 on the freeway when it's clear. Any ideas on what I can do to improve this? Thanks!!

it should go up. most people noted that the first few tanks were the worst.

check it again after 5 tanks.
make sure you are keeping the correct figures.

what were the first two tanks MPG

could it be since its still in the "breaking of the engine" phase?

carfixer · 06-08-2006, 12:37 AM

Post your math.
I got 30 on my first tank.

Davestoaster · 06-08-2006, 12:43 AM

Me too. I got 31 my first tank, and it gone up from there. Me thinks either it was bad math or you have some problems that the dealer needs to look at..

btodailly · 06-08-2006, 12:58 AM

are you using ac?

Max · 06-08-2006, 01:00 AM

My first tanks were mid 20s. Auto, city, easy driving.

Now I am at 31 for the last few thousand.

I've only filled up my car a few times so far. While using my xB to deliver newspapers at night and using AC during the day, I've gotten 32/30/30 mpg. I have a gas receipt from today in my xB right now and I could figure out another figure... going out to look... 28.5.

Fujiz_xb · 06-08-2006, 02:29 AM

yup it goes up. i remember the good ol days

06B0X · 06-08-2006, 02:43 AM

It does indeed go up. I'm going to hit 10,000 miles on my way home tonight.. *sniff sniff*

hotbox05 · 06-08-2006, 03:19 AM

lead foot with the parking brake on ?

CircoMetaForma · 06-08-2006, 04:16 AM

227 miles, 10.9 gallons to fill up...that = ~20.9 mpg. I have 18's but I bought mine used...it's got 7500 miles on it already! I'm frustrated to say the least. I use super vs. regular, but I don't think that wuld make a difference.

x-ray_Bravo · 06-08-2006, 04:40 AM

Are you calculating 10.9 gallons every fill-up, or are you looking at your gas receipt to see how much you are actually putting in the tank? I usually put 9-10 gallons in. I've never put 10.9 gallons in, because that would mean I ran out of gas. Just a thought.

CircoMetaForma · 06-08-2006, 04:42 AM

10.9 per my reciept...I ran it it to empty.

Englishman · 06-08-2006, 08:45 AM

i get 35 mpg out of mine with 9300 miles on the odometer.

i never use the a/c and usually short shift to keep the revs down.

ChefXB3 · 06-08-2006, 08:52 AM

Im averaging 32-33.5 MPG with 2600 mi on the odo
first couple tanks were high 28-29 range
Best tank so far was 35 mpg
worst was 27 mpg
I drive mostly highway around 68-70 mph on open road

Tomas · 06-08-2006, 09:57 AM

It *could* be driving style (not necessarily high speeds, but getting up to whatever speed rapidly will KILL your milage) or it could be something seriously wrong with the car, if your figures are correct.

There's another thread on here with some posted milage charts from actual use. One of 'em's mine, and you can see that my MPG has varied between 22 and 36 depending on how I drove the box.

My mileage went up and down a bit at first. Just give it a few thousand miles, it should go up..

XBdntusee · 06-08-2006, 11:42 AM

Yep, if you got 7500 miles and you are getting 22mpg then some thing is wrong. I got 28 for the first 1k miles or so now I have 3k and I am up to 30-31 consitantly. I run 89 octand and try not to drive to hard. ummm try!! Any mods? I also live in So. Cal., but I cruis at 75-80mph which is about 3.6-4 gs on the tack.
best of luck,
