27.7 Mpg
Just back from a 160 mile trip.
IS350 Tank Average for the trip was 27.7 per the on-board computer.
I used the cruise control set at about 65.
I also took a trip of about 180 miles and averaged 29.9 MPG but that was going around 55 miles per hour and that made the trip somewhat uncomfortable. 65 miles per hour/27.7 is fine for me.
I also took the same 160 mile trip averaging around 80 miles per hour and the miles per gallon went down to around 22/23.
What's your "Best Mileage"?

I want to hear you say that when we line up at a light...yeah, they're the same alright...like the same as an IS-F and an IS350.

55-60mph not with cruise control. the hills really kill the gas economy but only downshifted 3 times to 5th gear on highway for the 78 mi journey back to school. mostly rt 287 and 78 driving for your northeastern-ers. rarely went over 2000 rpm in an IS250 AWD. this is some serious clutch material
