I just purchased a black IS350 2 weeks ago. I have to admit the first 2 days I was pretty heavy on the gas but since then I've been getting around 14-15 MPG according to my display. I purchased the car with 12 miles on it and it has a few hundred now. I was wondering what other people are seeing? I live really close to work and don't drive long distances so I'm sure that contributes in some way.

To give you guys an idea, I drove a WRX before this and only had to fill up around once a month. In the 350 I might have to fill up every week if I keep getting the same mileage. Thats one hell of a difference.

 

14-15mpg?? Rock on brother Once you start driving like a sane person you should see around 19-21 mpg. I seem to get around 21-22.

 

I get around 21-22 in city driving with at least one daily full throttle burst to get around traffic.

Try resetting your mpg average by holding the Disp button down for a sec. You cannot reset the tank average.

 

I'm getting about 24mpg tank average, 50/50 city-hiway;
I gas it a bit --- but coast when I see a stop sign or red light way ahead (prevents brake dust too).

 

yeah ive noticed that im not getting no more than 15mpg... could it be because of the 10% ethanol in the gas...

 

i get 19-23mpg...50/50 city/highway and 50/50 speed limit/spirited driving

 

I get 18-19, a lot of spirited driving included.

 

holly 14-15 is really low

only have 900 miles so far , but for some reason when i started flooring it more on the highway i got my best avg mpg of 21.8 ...... =/

 

Please let your car break in before you start driving hard. I get around 17.5 City, not sure about freeway. I don't even care about the gas, its something you need, so why stress about it???

 

Gotta admit that highway saves mad gasoline, I can get mine up to 35.4 by driving Highway for two hours. But ya you need to do more high to get a better avg mpg. I got like 10-11 by doing local which blows

 

local i can get as low as 12mpg cause i'm 0.8 miles from work ( i don't drive everyday.. i skateboard to work when it's not raining). The lights really hit me hard... anyhow on highway i can get up to 26.5 going to vegas averagin 90mpg. Now if it's a a mix between local and highway i can get around 23~24...

so yes local does suck.. i don't drive hard going to work...

 

with 50/50 city/highway i get a good 20.5-21. i think our gas gauge however really is wrong because close to the e is about 320 miles which means its really conservative with a large reserve or my gauge is messed up.

 

i get average of 395 a tank with driving on the 405freeway at 90 miles round trip.

i think it's preety good if i only filled up about 14.5 gal.

 

btw,

do you all think the sports package will get better gas mileage than the standard one?

 

My averag is usually in the high 23's to low 24's.
