Just saw on the CBS morning show that the MT Scion xB was rated the 5th highest car as far as mpg. Hey these things are good for something. I Think I just paid 2.19 a gallon for premium. Now if iI could only remember what I was getting before the super charger. Lately when driving with light shoes on and staying out of the boost (right) I have been getting around 28 mpg. I know I hit 33 mpg with the stock xB.

 

wow.. im still on regular. and get 245 average with 2 gallons left

 

I've been using regular too and been getting 230 miles on one tank.

 

I've been getting 25mpg. Good thing, my last fill up was over $20 at $2.15 gal.

Yes, my low gas light was on.

 

i was so proud I got like 340 on a tank from full to empty that made me happy.

 

I can't wait until they get off the winter blend...

I'm currently about halfway thru my first tank since adding the Injen CAI. I'm very interested to see if there's any differences...

 

Only if you keep your foot out of it.

 

I got 24mpg first tank and 27mpg this tank. Is this normal for half city/half freeway? When will it go up to at least the 30's? I have ~500miles on the motor.

 

Lol good luck , I drive like a jackass constantly pushing this poor 1.5 for all it's worth and I get like 25 in mixed driving and like 28-35 in all highway under 75mph.

 

still at 250 average here

 

I just took the maiden road trip in the B and averaged 35mpg with a max of 38!

 

I average 32mpg
injen intake and ground wires, auto
and i drive like an a$$

 

Do tires larger than stock (e.g. 17", 18") wreck your mileage?

 

You usually decrease tire sidewall as you increase wheel size. If done right, your custom wheels/tires should maintain about the same diameter as the stocks. The weight and width of your wheels will have a much more significant effect on MPG, not to mention that heavy wheels will make your suspension work harder and not be as smooth.
