I was thinking the same thing. I suppose the way one drives is a big difference, but I posted in another thread looking for reasons for variations, and I think tire size could make a difference (going from 18" to 19") for example, getting low rolling resistance tires, and summer vs winter gas as simple reasons.
I am going to post in the hybrid thread, but so far in about 1000 miles, my wife has been averaging 30mpg. Considering the EPA range is 29 city, 34 highway, I suppose that is not bad but I have been trying really hard to see the high end of that range, and I have not been able to achieve it, but mind you, I can't drive 55 (in Sammy Hagar voice), so perhaps that is the reason, lol
For some with really low MPG, that is really odd, my Ranger Rover, all 6000lb and all, with a 5 liter supercharger averages 17-18mpg city/highway, probably 80% highway. I'm not going to say no way should a GS 350 be worse than that, but, no way should a GS 350 be worst than that.

Well, the MPG struggle is real! My 2013 GS350 with 18" wheels, driving in Normal mode MPG is pretty bad. Check this out the computer readout as most of my trips average less than 8miles total in NYC driving - lots of stop lights, stop signs, speed bumps, potholes, and of course, a**holes:

Thats on half a tank of gas. At the current rate, that average will drop from 18 to around 13-14mpg. My dad has a 2011 GS350 and does only city driving...he gets about the same (and his GS has only 40k miles).

I’ll report 3 vehicles for you. All 3 are typically fueled at the same station. My 2015 GS350 F Sport (RWD) and my wife’s 2015 IS350 Convertible (RWD) both get a consistent diet of premium fuel. I’ve never heard of running anything but premium in the GS or IS. My 2004 Suburban 4x4 gets regular fuel. The calculations below are mathematical (miles driven divided by gallons consumed) and are not based on the vehicles’ fuel economy estimation system. All calculations have had several thousand miles to average out and are all based on the cruise control set at 80 MPH on the Texas interstate. The GS350 has averaged 27.2 MPG (in ECO Mode). The IS350 has averaged 24.7 MPG. The Suburban has averaged 14.9 MPG. All three vehicles are totally stock and run tire pressures per the label inside the door jam.
