Here's my question to other IS250RWD owners, I'd like to know what kind of MPG they are getting from them. At this point I am very disappointed from what I've gotten. After a week of having this car an average of only 23 MPG!! which it is pretty poor as the window sticker claims 24/32. I hope somebody here has any input about this. Ok I need to clarify that I am a conservative driver.

What does your political philosophy have to do with gas mileage?
 
Is that mostly or all city driving?
 
Yeah the EPA rating on the Auto RWD is suppose to be one of the draws of the car but if it's not living up to it....
 
It's close though, unless that 23 MPG has a lot of highway driving.
 
Are you calculating it or looking at the trip computer reading?

wco81 You got me here, I don't have to explain english is not my native language
 
I live in Miami (bad traffic), so yes mostly city driving with some expressway here and there, but is there suppose to be any difference between my calculation and the computer reading? what's the average you're getting from yours?
 
nyccarguy says something about the engine being "green" after only a week of driving... let's see... today the computer showed 24 MPG avrg after a busy day in traffic; maybe I need to be a little patient with this baby.

#5 of 41 What's your IS250 gas mileage? by chaslewis2004

I tested a RWD IS250 today, and now I'm wondering what the REAL gas mileage is. Cmon, owners, lets hear your stories. The window sticker says 25-32, I seem to remember, but I can't help wondering what the reality is. Thanks.

Just finished my first tank. IS 250, 18" wheels, premium package. 28.3 MPG, 90% Hwy mileage. Still in break-in mode. Expect MPG to improve another 3-5% after 20-30 K

#7 of 41 IS250 AWD MPG by wayde

Responding to an earlier post. My first fill up was 24MPG (trip computer was right on).... this was about 50% hwy / 50% city. I was amazed at getting this good of mileage on the first tank for an AWD car. (My previous car, a Protege5, got about the same mpg and it is much smaller, lighter.)

Not sure about AWD mileage. My RWD is getting high twenties per tank.
 
At winter time, you drive it with heater on.
At summer time, you drive it with A/C on.

Hi, I've had my IS250 AWD for about 3 weeks. I'm getting 26-27 MPG on a tank of gas. I'm at about 75% freeway miles. I use the sports mode quite a bit during city driving. Once I get up to speed on the freeway I throw it into auto mode.

Can't answer this one yet Sorry.
