im usually driving in the more suburan areas in ny. other then that highway sometimes. its just that when i fill the tank up it say i got 280 approx miles...

RAMAIR

Almost Everytime I fill up it is at 398... I have been trying to get it up two... I have a 2007 250AWD... I use premium every time, I seem to drive about 60% City to 40% Highway....


Here is a crappy pic.... but when I was driving pure highway doing 75 with the cruise controll on.... Drive like a granny, its possible.


Sorry about the crappy pic... from my phone.

I know the first 6 months or so after I got my 350, I was barely getting 325 out of a tank (lead foot and all...) Now that I try and conserve gas a little I'm getting closer to 370-380 on average per tank. I drive about 70/30 hwy/city. Of course it always goes down when I feel my foot getting heavy again.

I've gotten close to 475 on a tank but my overall average with about 50-50 city driving is about 31mpg. I drive pretty conservatively.
I hit 300 miles with the tank showing at half at one time.

For those of you listing how many miles you get a tank, it would be great if you listed how many gallons you filled up too. Saying this because what one person considers a "tank" another person may consider it differently. Is a tank right when the light is lit up? A little before? Bone dry?

For my 400 miles, I consider a tank when the approximate goes down to 0.

I hit 400 miles all the time. But I am not refilling until my approximate mileage says 0.
My best was 428.
I believe in the winter it should be much better as florida summers are brutal on engines.

2007 IS 250 AWD. I get about 428 miles on the approx range screen

Just hit my first 400 the other day. 85% Highway / 15% City. Conservative driver.
Consistantly between 375-400 though. IS250 AT.

I run AC on blast though here in the Texas heat. Wondering what it will do when it starts to get cooler since I bought the car in July.

best I've gotten in my 350 is 413miles. Long trip from Boston - Bar Harbor, Maine.

370-380 is consistent for me. 75% highway

I consistently get 475 miles on the electronic range meter, and then I sometimes drive 30-50 miles more after the range hits 0.

I mainly drive highway (is250 manual).

i get around 380 a tank on my 06 250 so 400 doesnt seem impossible. and i do mostly city driving

Most i've gotten on my IS350 is 395 miles. I drive about 70/30 mostly highway miles. If I drive spiritedly non-highway driving I get about 330-340 out of a tank. However I would say my average is 375 our of a tank. I'm sure i'll hit 400 eventually.

I will say that i used to own a IS250 awd and I did not notice a difference in gas mileage. As a matter of fact i've gotten more miles out of a tank in my 350 than I did with my 250. It's very easy to keep the car below 2500 rpms in a 350 than it is a 250.

The majority of my driving is highway, so I get around 400 (probably slightly less) fairly frequently. It's awesome, especially when coming from an SUV that maybe got 22MPG Highway. sucks for you ISF guys though. I guess if you can afford the car, you can afford the gas.

I own a 2008 GS-350 RWD and I am consistantly getting 30-32.3mpg over the distance from San Jose (101) to CA-152 to I-5 to Irvine , Ca. That is with premimun fuel and 78-84mph with air-conditioning. I fill up in San Jose and at CA-58 near Bakersfield each time I go home. The car is used for commuting and has over 71k miles on it since Nov 2008. I use the car computer and then manually figure mileage. Does not vary more than +/- .4mpg. The tires I had were Yokohama Advan 10's, 240 x 45 x 18 R. I just change last week with over 46k on them to Michelin Pilot Super Sport 240x45ZRx18. At first i was very concerned becasue it felt like I was being held back. But I filled up with gas and then teh "tire pressure light" came on. I checked the air pressure and found that teh dealer only put 27psi, not the 34psi I requrested. I fille dtires to 34psi and off I went back to San Jose to work. The tank of gas to Ca-58 gave me 29.3. Filled up and went eh last leg up I-5, across CA-152 to Ca 101 and to my apt. The computer read 29.0mpg. Not bad...It was 89 degrees F, air on and still got 29.0 I cannot complain at all. The ZR tires are very sticky, but really give me a soft and confortable ride without any NOISE! The only set back is they are probably only going to give me about 30k miles. If teh Yokohamas Advan A10's were just so expensice ($334 ea), I would put then back on. I liked hte tread design and the lasted for +46k miles. SO I am a happy camper not only with teh car, but how it handles. My previous ride was a SC 300.......that was the best car I ever had....
