Model 350
MPG 20
60%city / 40% highway
octane used 91
full tank 340
traveled miles 1400
I don't think it's too bad, considering the 5 series I traded in for this that got a MPG of 18.

IS 250 AWD AT
18/19 MPG
75% City/25% HWY
91 OCTANE
TANK OF GAS : 310 TO 330 MILES
Im sure if i did more highway miles id get anywhere between 24 to 28 miles. The guys who are getting these numbers already in city driving should consider themseleves lucky. Hopefully MPG goes up as i accumalate more miles.

350 and mpg seems about 18.5 for a tank & about 270 miles..going by the little screen thing. I hope it gets better, I thought I would get better mileage than my S..I also use 91 only.

I definitely noticed an increase in gas efficiency as I put more miles on my IS350. The first day I had it on the highway (with about 130 miles on the odometer to start, driving 2700 miles to bring it home), it was getting about 22 MPG. By the end of the four day trip, it was getting about 27 MPG, and seems to be staying around that mark now for freeway driving.
My advice to people who are seeing poor efficiency: break it in first, then see what you get.

22.7
40%city / 60% highway
91
350 miles
I was using the paddle shifters for about 15% of the time
On the display it says 22.7 mpg on each tank. First time i filled up, it had 350 miles and i filled 15.26 gallons....so that would be 22.9 mpg. So the display is pretty accurate. I only have about 450 miles on it so hopefully it will get better when its broken in.

Yesterday when I filled up to the max, I was shocked to see my total range to be 280 miles. I figured it would go back up or something, but I didn't. My first two fill ups in my car showed 300+. I hope it doesn't go down any lower. As for MPG, I do mostly in city, and get like 18-20mpg.
Also, what gas do you guys use? I've been filling up with Cheveron 91.
900 miles
18 - 20 mpg
70% City / 30% Interstate
Range 280 Miles
Cheveron 91oct
