I have a 2014 GT sport and ever since I got the car it’s had terrible mpg (like 7.1mpg). I don’t drive like a lunatic and no matter how I drive my mpg stays around 7- 9. What in the world can this be?
Guys please help (Terrible mpg)

City driving only, you should still be getting around 12/13. Does the car run smooth, idle smooth, any missing in the engine, sputtering, is the acceleration ok?
I don’t really know much about cars but from what it looks like the car runs perfectly. It accelerates great, drives nicely, idling sounds normal (I think). I love everything about the car other than the fact that gas cost is insane.
Dash says 7.1 mpg

Fill your tank, reset trip mileage and see what mileage you're getting for a whole tank.
Recently filled up and putting the mileage to the test. The first few days it read 7.1mpg as usual but now it says 7.9 mpg so it’s going up slowly but still ridiculous. At half a tank right now. I will reply back to you when I’m near empty. Let’s wish for the best.

We have the same GT, a 2014. Fuel capacity is 22.72 US Gal, including a 4.75 reserve. From a full tank, when your fuel light comes on you have burned 17.97 US gals. At this point, take your mileage and divide it by 17.97. You should see a more accurate reading, this way. 👍🏾
I’ll look out for the light. I remember the guy I bought the car from said the fuel light comes on a bit early. I don’t know how to fact check this since I don’t know when the light is supposed to come on. When it comes on I’ll send you a picture how does that sound?

Cool beans...it comes on with 4.75 gallons remaining in the tank. It's right around a 1/4 of a tank. And it will seem a bit early but I guess that's not a bad thing. 😝
Thank for your help. How’s your car treating you so far?

Car has been a joy to own and to drive. Since August 2018.
That’s great to hear. Let’s wish for the best of luck with both of our cars 🍻

You might consider a tune up and fuel injector service to see if that helps your fuel economy. New air filter, new spark plugs, get the fuel injectors cleaned. No need to go to the Maserati dealer for any of this, just find a competent shop in your area if you don’t do your own maintenance. Oxygen sensors can cause problems as well but I would not just go out and change them. Any competent shop can hook up a reader and see what the voltage is running on the sensors.
The fuel light doesn't come on at exactly the same point each time.
The standard way to measure mpg is to fill up a full tank, drive to near empty, then fill up a full tank again and divide miles driven by fuel used.

You can even measure at half tank which will get you reasonably close. The more fuel from a tank you burn the more accurate your average fuel economy will be.
That’s crazy. You never looked into it or is it how it’s supposed to be?

I have no idea if it does or doesn't. Info is according to fuel capacity as listed in the owners manual. Either way should work.
My 2013 gets slightly over 20 mpg (calulate 22 mpg), on the open interstate with cruising speed about 70-80 mph at about 2,500 rpm, depending on speed limit. My 5.6 liter Nissan VK56 engine in Armada SUV in town gets about 11mpg. What I am saying is that 7mph not completely out of the realm if a lot of city stop and go driving (especially if you are going by speedo and not calculating according to how many gallons it takes to fill up and miles since last fill up..
