Struggled to go above 40 Miles

[QuantumRift]

It seems one needs to have some luck to get a good engine and good car. I have not seen better than 17 MPG in the dashboard for the city driving. Hope that improves.

Always be sure to calculate your mpgs the old fashioned way by keeping records of your fill ups: Fill up, then drive. When you are ready to fill up, note the trip meter (if you reset it between fillups) or odometer reading. Then, divide the amount of fuel you pump in the gas tank into the number of miles driven. I'm sorry of this sounds so pedestrian but I never EVER wholly rely on the CPU to tel me my milage. IT's good but not super accurate. The best way to fill up the same each time, say until the first click on the nozzle. After several tanks you will get a much better average of your fuel economy. I have had the mpg meter on my Suzuki motorcycle act wonky once in a while as well on another car which usually corrected itself after a reset)

I agree totally. I’ve always used this method to keep track of MPG. I’ve never reached some the lofty heights noted here by others and the display has shown those magic numbers periodically but my reality check on tank fill up calculation has proved less optimistic. Still all things considered I am quite satisfied with my results. I’ve had much worse with less rewarding cars.

Hello Everyone,

I bought a 2011 Genesis sedan, 3.6 about 3 months ago. Since the purchase, I have taken the car on several trips (100+ miles each), and am only getting 21 - 22mpg in almost exclusively highway miles. Combined city + highway mileage is consistently around 16 - 17mpg, when not considering the longer trips. My manual fuel consumption calc's very closely approximate the car's computer, 21-22mpg on the highway.

I have tried gas from several locations, as was suggested previously in this thread, but there is no noticeable difference.

I have taken the car to the dealer, but they are at a loss as to the cause, though they have driven the car and confirm the mileage is considerably less than expected. The car's power steering pump went out recently, and the dealer has now had the car for almost a week since, waiting on the replacement pump, and are planning on doing their own fuel consumption - believe this is computerized - study. At this point, I am at a complete loss. I was thrilled when I first got the car, but the poor gas mileage is completely souring me on it - even though I have traveled about 30% of the time for work, so was not driving the car, I have still had it in the "shop" 9 days over 3 months (less than 2 months if discounting the time I was away for work) that I have owned it.

Hoping, hoping, hoping someone may have some suggestion(s) not previously shared in this thread...
