Hi guys, I’m wondering what kind of mileage you all getting in a full tank of gas?

I finally went thru my first tank of gas on my new 2018 GS-F. I only got 250 miles per tank. is this normal? I didn’t push the car hard at all. Normal driving 60% city and 40% highway. Is this because engine needs to break in? Will my mileage improve?

I seem to fill up around 300 miles which is around 1/4 tank (takes about 13 gallons at fill up). Usually average 22-23 mpg, which is with 60% highway, 30% backroads, and 10% city. Been as low as 20 mpg on tank and as high as 30.5 mpg (all highway). I do have fun, but with my typical commute there are only so many times to accelerate hard, especially with traffic.

those aren't bad numbers.. i make it to about 200-230 miles, but i fill up before the light comes on and i'm about 90% city driving and average between 15-16.5 mpg.

my best on this car is only 19 mpg and that is on highway driving on normal to sport mode. If you get 20 plus mpg on this car, that is already above average and the oil level is just right. Anyway, I enjoy it and did not buy this car for good mpg anyway.

I too am in the 15 -16 mpg club of mixed 80/20 city/highway driving.

over the 4 months that i had mine which i bought used with 8k miles on it with basically 100% city driving in chicago i average 15.9 mpg. and usually get bout 210-230 miles on a tank.
the few times i took it out on the highway to take it to a shop to do my tints and another to get the roof wrapped it got amazing highway mileage those specific trips i got 24mpg highway. those times i got 260 miles out of a tank.
so its not great on gas but also not terrible

I did not buy this car for MPG. I come from three different GSes in the past and I'm not used to pump gas so soon everytime. I guess I need to enjoy the car more and get used to the lower MPG I'm getting

Way low, lol. I just can’t help it. The gas pedal and my foot are lovers.

I took delivery of my 2016 Liquid Platinum GS F recently. I averaged 26.0 mpg as I drove from Augusta, Ga to Jacksonville, FL on mixed Interstate, state and county roads.

I've put about 13K on my 2016 and I get a consistent average of 20mpg. I drive mostly quick highway trips and back roads, very little city and like to hit the gas but generally keep it in standard mode. If I take a long highway trip and keep it in standard/eco mode, i average around 23mpg.

My last fill up gave me an average of 22.3mpg. I can live with that.

The worst mileage I saw was when car was new. I used manual to keep the engine under load both on acceleration and deceleration,,,that was a miserable 17-18mpg. But doesn't matter cause I bought the car for the enjoyment of driving it not mpg.
