Gas mileage of the IS-F

At the track it averages 45-48 L/100, no idea how much that is in MPG it it uses a lot of fuel.

Those are great numbers. My best so far is 24.3 mpg on long distance runs to Northern California averaging 80mph. Are you calculating it by: Miles Driven/Gallons filled?

i get 25-26 mpg cruising at ~ 75 mph. cruising at 55 mph, i have even got 30 mpg. these numbers are regurgitated by the trip info computer, not sure how trustworthy it is.

I average 15mpg of only city/suburbs driving

My around town and mixed driving gets me between 20 and 23MPG. I think that is really great for a car with this Fs potential. It's better than my G35 was.

I get about 16.7L/100km (~14 mpg) on my first 2900km (1800 miles). However, I treat my gas pedal as an on/off switch rather than a variable

I've gotten 26mpg as well with tons of freeway driving and not going over 75mph. I usually average 18-22 mpg with mixed driving.

Mine stays around 15mpg in suburban driving. Mostly because of all the stop signs and lights I have to pass getting to school, o and minivans cutting me off.

My wife drove my neice back to Waco from Longview and she is a little lighter on the go pedal and got 28mpg. This was going the long way down I20-I35S. 240miles/8.5 gallons=28.23 mpg. I love this car!

city driving only and i get 17 mpg at most.

My MPG have been pretty poor, ever since I got the car. I'm averaging 16-17mpg combined driving, and most of that is highway. Part of this maybe that when I'm on the highway, I'm usually doing about 75 to 80mph...okay, mostly 80mpg . But would that make such a huge deal on knocking down the MPG than if I was doing 70mph?

I'm glad you said this, because this is exactly what I am getting for mileage, 16.8 avg lifetime to be exact. I also run mostly highway and cruise at 80 mph. But in my case, it's the first 1200 miles, so maybe it will improve now that its broken in a bit.

This week has been raining so I have been avg 20-22mpg. I usually avg about 17mpg on mixed city/hwy driving conditions, majority of it being highway. When i feel a little spirited, I avg about 15mpg with sport mode on. Suprisingly with the car being under 2k rpm most of the time, even between 70-80mph, like some of you have mentioned, the mpg keeps climbing!

All highway when going 70-75mph the whole time I get 26-29mpg.

All highway when going 80mph the whole time I get 24-25mpg.

I get an average of 315 miles on a full tank when I drive all highway.

Street I drive ridiculously sometimes so I ignore the mpg.

I drive between chatt-a-vegas (chattanooga) and atlanta weekly (140 miles) almost all interstate 75/85 with cruise set at 80mph and get between 27.5 and
29.2 mpg - loving it!

I'm getting about 19 mixed city/highway driving. Drive mostly in F mode/sport, and I have a heavy foot.

What is gas mileage?

lol BigMike... I'm averaging 11-12 MPG believe it or not as it's all city driving with traffic and many traffic lights!! I'm gonna go for a long trip soon and we'll see what it can offer
