Hi CL,
Drove my F for about 2-3 weeks now. What kind of MPG are others getting with the stock GSF? I was getting 11 MPG off the lot, after oil change and full tank of gas, I'm getting 13 MPG. Mostly local, normal mode, and never above 3000-4000 RPM. I know they aren't gas savers, but this sounds a little low for normal everyday driving.

I get around 17 to 18 MPG.

 

I'm going on 6 months of ownership. Mostly city driving with weekend highway driving with a mix of normal/Sport/Sport+ modes. I'm getting in the 15-16 range on average. I'd like to see what i'd get with highway driving only, but am too tempted with my heavy foot.

 

I'm getting about 18mpg. Mostly in normal and sport mode, averaging about 20 mph.

 

That's nothing. You'll need a few thousand miles to break in the 'efficiency' so to speak.

 

I am getting about 20-21mpg on mix driving. 24-25mpg on highway.....

Thought I was pretty hard on the gas already....

 

OK. Thanks. I will give it some time then. Everyone else had this condition on their first thousand miles or so?

 

I have had mine just under 2 weeks and averaging so far 19.6 mpg in normal/sport. I averaged 24 in Eco. I commute 9 miles one way (18 miles a day) to work and it is a mix of hwy/city. Sounds like you are either hard on the gas, the engine hasn't really broken in yet, or something is wrong. To compare I am coming from a 2015 Z06 and only averaged 14.5 on that commute in sport, and 15 in eco.

 

Short trips and stop and go traffic you can get 11 to 12 MPH.

 

15-16 mpg mostly city. 11-12 seems a bit harsh in my opinion but that is just me.

 

I have 16K on it now since July. Do 90% highway driving and I'm getting 19-20 mpg in Sport mode. WOT twice a day, each way to and from work. 11-12, I would have to drive it like I was at the track with RPM is 4-6K constantly... which would get tiring

 

Wow, I dont know how some ppl get over 20mpg. After 7500 miles, my computer says 17.3mpg mixed city/freeway driving for me.

 

Lots of factors in MPG. Driving habits, time of day (i.e. heat and humidity), traffic, and fuel quality are just a few. Some have reported that they had too much oil after the dealer did the service that caused lots of MPG loss.

 

I use Sport S and S+ exclusively, mostly city driving with lots of stop and go, and get 14-15 mpg. S+ really eats into things only using the first 6 gears but I can't help but turn that on any time I'm not in traffic. On road trips that are mostly highway it's mid-high 20s and the mode doesn't seem to matter. ~7k miles on the car with those numbers.

At the track I get ~7 mpg
