Is my MPG this good?
So I am a new E550 owner and I'm convinced my computer is not calculating the MPG correctly. 
Yesterday I got a solid 28.5mpg on the highway while cruising at 65-70mph. My buddy who owns a G37 has already made a comment to me about how much gas this car will sip. So far it's identical to my GS350 or maybe even a bit better unless the computer is wrong of course.
Anyone else get this kind of number from a RWD E550?
Thanks.

Driving slow like that on the freeway (esp if using cruise control) and they can do okay. I can get 24-25 on the freeway with the 63 motor. But it's kinda hard to be so vigilant.

How does the GS350 compare to the E550. I was considering buying a GS350 or G37, and test drove a 10. More power than the new E350 with both being V6. Just wondering how the two compared by someone who owned them.

yup i was getting about 16mpg around town, stop/go a lot.
Then after seeing what everyone got on here i tried again but on the motorway (our eqiv to a freeway) and was getting around 23-24mpg. I can see if we had flat roads and being a little more careful i could get up to 27 or so but this is a v8 5L everyone .... where is the fun in driving smoothly
:P haha

My E350 is 80%+ highway and I'm pleasantly surprised that I'm averaging over 27MPG on fill ups now. On my trip computer, for a 240 mile trip, it read 29.9MPG. I was hoping I would see the magical 30.0 but I neared home and the reading dropped as I drove on streets to get home.

The GS350 must get some crappy mileage if a 5.5L V8 is doing around the same. Lol, toyota and their "green marketing". Ya the G37's don't do well at all with gas mileage compared to many cars, especially since it is a V6.

My old 5-Speed S500 was able to get a comfy 28 MPG on good roads/days (Highway).
My E can do 28 easily, and has even gone up to 29! Almost reached 30 a few times to boot.

Yup, my '08 E550 easily does over 25mpg on the freeway. I've done one or two 120mile round trips, almost all highway and had the computer report 27-28mpg. I find if I do the math manually at the gas pump, the computer shows 1mpg higher than actual, but yes, the our V8 5.5L w/ 7G = amazing.

My C55 back in the day never got anywhere near 28.5mpg on the highway so the transmission must be making all the difference in the world.
