I've gotten up to 33.5 MPG on my IS350 all highway miles using cruise control the entire time. I confirmed it at the pump. Of course that was with 70 mph tail winds.
I normally get 28-30 highway miles. I'm easy on the pedal. City driving is a different story (wink wink)

I guess.. if I were to slow it down some my gas milage would increase.
I have about 7500 miles and I average 24.5 on the interstate at about 80 to 90 depending on my mood. Maybe if I did the speed limit my mileage would increase.. but on open interstate its kinda difficult to do. Hehe
When I fill my car up it reads about 376, the most I have ever got to do with the gas light coming on is 368, and it claimed I had 30 more miles left. = /

You have a 3.0L engine on non-US gas. Not going to get good comparable sampes here from most members, but 19.6 is pretty average for a city driven IS350.
but your car is still not broken in yet either, so hopefully your number goes up.

I'm back up to 26+mpg as the weather's gotten warmer and we've got the 'summer' blend again (and not that oxygenated crap.) I was avg around 27 mpg last summer with a ~75% highway commute, some of which is stop and go.

Curious what everyone's getting on their dash readout and comparing the 250 and 350. Granted I'm only on my 3rd tank of gas, my 250 says about 24.5 during the break-in period driving in 90% stoplight and stop and go interstate traffic.

24.5 mpg is about what I have been averaging with my 350 over about 5000 miles. I like to drive it fast/accelerate fast but I don't race up to red lights and stop signs.

26.5 avg on my IS350 over the last 6,000 miles.....about 80% highway miles and 20% city. Just took a 1,700 mi trip to Santa Fe and averaged 28.5 mpg for the entire trip. No complaints.
