I just checked again and I'm at like 430 miles now.. 300 was a few days ago - but I'm on a 10k/year lease for 27 months so I'm trying not to rack up too many miles!

I definitely didn't buy the car for being good on gas mileage, but I expected in mixed driving I'd get ~22-25mpg and I haven't seen 20mpg yet. I am not usually driving in traffic (I tend to drive to work / home during off hours) - but I do obviously hit traffic lights and stuff on some of my commute.

Drove in eco all day today and feathered the throttle almost the whole way (had to rip into it once or twice) - and I think the navigation screen said the average was about 21mpg which isn't too terrible. Total on the tank from the mid was around 19mpg total though.

Hopefully as others said the mpg will improve as the car breaks in! I'd like to try to drive it however I feel like and not worry about mpg but still get somewhere around 22-25mpg

Almost 30K miles on car and continually get about 19 mpg with mixed driving. Straight highway mileage about 26 mpg. Not an F Sport but AWD with the 6 speed.

My GS is well broken-in with 17,500 miles and I've reached 22 mpg on short highway drives but typically average 17-18 mpg in the city. I don't consider that terrible. Just realistic.

yeah the MPG on the GS is ****. We have V6's but it drinks gas like its a V8. This is a known problem but nobody bought this car for fuel efficiency

sick21

Very true. My window sticker does say 19 and 29 mpg though and it would be nice to actually achieve that but it's looking more like 17 and 26 to me.

I had this issue when I first got my car as well, you need to give it time and it will get better.....unless you get an exhaust.

I'm at nearly 12k after my first year and I average 19mpg mixed, lots of city driving. Best I've gotten on the highway (not 100% highway) is 25mpg. I may take a good road trip soon and have 100% highway, point to point between gas stations, and I'll see how that goes. I expect close to 30.

You think an exhaust will help with the gas mileage? What about a CAI? I haven't seen headers for the car.

In my last car, I added a CAI, Headers and Exhaust and added roughly 4mpg plus some extra hp too - was really nice.

I think he was suggesting the exact opposite actually.

Yes I was suggesting that an exhaust will make it worse than your situation.

LOL - oh hahaha - I totally misunderstood. Is that just because you're on the gas all the time to hear the exhaust though?

I filled up my tank yesterday - got 19.71mpg according to my phone app, 19.4mpg according to the car, pretty close!

I babied the car and did mostly highway driving on the way to work and the car reported I was getting 21mpg - woohoo But then I went out to lunch with my co-workers, wasn't paying attention and when I got back in the car to go home the car said I was getting 17mpg haha...

I guess I just have to deal with it until I put enough miles on the car.

Drove my wife's 2011 ES350 last night on a trip up to my parent's house and did full highway driving and got 29mpg reported by the car and that was with me cruising at ~80mph half of the trip. She gets 25mpg regularly in mostly city driving too - I'd love it if I got that - but the AWD and extra weight may have some influence there - plus she drives a lot slower than I do

I got much better mileage in my 2010 ES than I do in my GS, but the GS is much more machine. The tradeoff doesn't bother me.

NewSpace

So 8 speed trans doesn't help mpg?

SW17LS

His is AWD, so it has the 6 speed.

Totally agree - I don't really like driving the ES but my wife likes it. The GS on the other hand is a different story - I actually look forward to driving it everyday

I was just curious if others experienced the same kind of gas mileage as I do and if it would get better as the miles increase .. and it wasn't something wrong with the car or anything.

If price were no issue, I think I'd be happiest with the new 2015 GS450h F-Sport - best of both worlds! Although if price truly were no issue, I wouldn't care about mpg, and I'd be driving a Ferrari or some other supercar hahaha...
