I would also have to agree -- since it's a new car, you have to break it in. I have a IS250 AWD and in the winter in Boston -- I still have about 26mpg Highway. The key thing is to check your tire pressure. When it's cold, the tire pressure drops. So better off checking your tire pressure.

i just filled up like 2 days ago and i pulled almost 320 to the tank.but the dealership prolly put 87 in the car.now that i run 91 i can see it drop a little quicker than before.then again i only have 440 miles on the motor.i hope it will get better over time.ive noticed in the past with my other vehicles that i have had that you can get a bad batch of gas from time to time.but you should see it get better over time.and be easy on the throttle to lol
