Be happy with your 20s. 350 AWD, I'm getting 16MPG ~ 14.6L/100km. Mostly city and up a mountain.

On another note, does the "After Reset" on the F sport dash ever go away?

Hey cFoo, not sure if you're in the Lower Mainland, but i'm commuting in heavy traffic each day from Richmond to Burnaby, and consistently getting about 12L/100km. On the open road I get between 9 and 10L/100km. And I drive in Sport mode in the city and Sport+ on the highway.

So I'm not sure how you're getting such poor mileage? I am not driving mine gently, and it's also a 350 AWD (F-Sport).

Took a trip this week-end from CT toward the RI beaches, got 28 MPG on the way down and 25.5 on the way back driving between 65 and 70 MPH most of the time. This was with an IS 350 F Sport and this was just the highway driving only

My baby still hasn't hit 1000 miles yet, but so far been doing ~18 MPG combined highway & city.

Oh yeah... I live in the South Bay and work in downtown LA (for any of you SoCal folk).

I have a IS250 awd f-sport. According to the car's fuel menu, I'm getting 33.5 mpg average. I have the mpg reading to reset after start which is showing 28.9 mpg for ~35 minute drive to and from work. Not sure how accurate the cars mpg calculations are and in the process of doing my own calculations to test the accuracy. Also, I have 600 miles on the car so far.

How to do you go about to make it reset every time you start automatically?

I posted my MPG on post #161 and that really hasn't changed but my wife just got 2014 Acura MDX and this morning I drove it for ~30 miles and was able to get 28.7 MPG. This is almost the same route I do with my Lexus IS350 F-Sport which is slightly under 25 MPG. I was pleasantly surprised with MDX's result!

I'm with a 2014 IS250 loaner right now and so far for a week I've averaged 26 mpg on nearly all city use. The one time I had it on the highway it was averaging 31. My 2008 is similar. I think for a quiet and refined V6, this is quite good.

It's in the settings somewhere in the instrumentation cluster display. I'm away from my car right now, but I'll write a procedure up later when I get a chance. Take a look at the attached pdf. I highlighted the areas that are related to changing the reset.
